                          DESCRIPTION OF THE FUND
GENERAL
        The Fund is intended to be a funding vehicle for variable annuity
contracts ("VA contracts") and variable life insurance policies ("VLI
policies") to be offered by the Participating Insurance Companies. The Fund
currently does not foresee any disadvantages to the holders of VA contracts
and VLI policies arising from the fact that the interests of the holders of
such contracts and policies may differ. Nevertheless, the Fund's Board
intends to monitor events in order to identify any material conflicts which
may arise and to determine what action, if any, should be taken in response
thereto. The VA contracts and the VLI policies are described in the separate
prospectuses issued by the Participating Insurance Companies over which the
Fund assumes no responsibility.
        Individual VA contract holders and VLI policy holders are not the
"shareholders" of the Fund. Rather, the Participating Insurance Companies and
their separate accounts are the shareholders (the "shareholders"), although
such companies may pass through voting rights to their VA contract holders
and VLI policy holders.
INVESTMENT OBJECTIVE

        The Fund's investment objective is to provide investment results that
correspond to the price and yield performance of publicly traded common
stocks in the aggregate, as represented by the Standard & Poor's 500
Composite Stock Price Index* (the "Index"). It cannot be changed without
approval by the holders of a majority (as defined in the Investment Company
Act of 1940, as amended (the "1940 Act")) of the Fund's outstanding voting
shares. There can be no assurance that the Fund's investment objective will
be achieved.
MANAGEMENT POLICIES
        The Fund attempts to duplicate the investment results of the Index,
which is composed of 500 selected common stocks, most of which are listed on
the New York Stock Exchange. Standard & Poor's ("S&P") chooses the stocks to
be included in the Index solely on a statistical basis. The Fund attempts to
be fully invested at all times in the stocks that comprise the Index and
stock index futures as described below and, in any event, at least 80% of the
Fund's net assets will be so invested. Inclusion of a stock in the Index in
no way implies an opinion by S&P as to its attractiveness as an investment.
The Fund uses the Index as the standard performance comparison because it
represents approximately 70% of the total market value of all common stocks
and is well known to investors. An investment in the Fund involves risks
similar to those of investing in common stocks.
   
        The weightings of stocks in the Index are based on each stock's
relative total market capitalization; that is, its market price per share
times the number of shares outstanding. Because of this weighting, as of
November 29, 1996, approximately 46.3% of the Index was composed of the 50
largest companies. The Advisers generally select stocks for the Fund's
portfolio in the order of their weightings in the Index beginning with the
heaviest weighted stocks. With respect to the Fund's assets invested in the
stocks in the Index, the percentage of such assets invested in each stock is
approximately the same as the percentage it represents in the Index.
    
        No attempt is made to manage the portfolio in the traditional sense
using economic, financial and market analysis. The Fund is managed using a
computer program to determine which stocks are to be purchased or sold to
replicate the Index to the extent feasible. From time to time, administrative
adjustments may be made in the Fund's portfolio because of changes in the
composition of the Index, but such changes should be infrequent.
        The Fund believes that the indexing approach described above is an
effective method of substantially duplicating percentage changes in the
Index. It is a reasonable expectation that there will be a close correlation
between the Fund's performance and that of the Index in both rising and
falling markets. The Fund will attempt to achieve a correlation between the
performance of its portfolio and that of the Index of at least 0.95, without
taking into account expenses. A correlation of 1.00 would indicate perfect
correlation, which would be achieved when the Fund's net asset value,
including the value of its dividends and capital gains distributions,
increases or decreases in exact proportion to changes in the Index. The
Fund's ability to correlate its performance with the Index, however, may be
affected by, among other things, changes in securities markets, the manner in
which the

                                    Page 4

Index is calculated by S&P and the timing of purchases and redemptions. In
the future, the Fund's Board, subject to the approval of shareholders, may
select another index if such a standard of comparison is deemed to be more
representative of the performance of common stocks.
        The Fund's ability to duplicate the performance of the Index also
depends to some extent on the size of the Fund's portfolio and the size of
cash flows into and out of the Fund. Investment changes to accommodate these
cash flows are made to maintain the similarity of the Fund's portfolio to the
Index to the maximum practicable extent.
        From time to time to increase its income, the Fund may lend
securities from its portfolio. See "Appendix _ Investment Techniques." When
the Fund has cash reserves, the Fund may invest in money market instruments
consisting of U.S. Government securities, time deposits, certificates of
deposit, bankers' acceptances, high-grade commercial paper, and repurchase
agreements. See the Statement of Additional Information for a description of
these instruments. The Fund also may purchase stock index futures in
anticipation of taking a market position when, in the opinion of the Advisers,
available cash balances do not permit an economically efficient trade in the
cash market. The Fund also may sell stock index futures to terminate existing
positions it may have as a result of its purchases of stock index futures.
See also "Investment Considerations and Risks" and "Appendix _ Investment
Techniques" below, and "Investment Objective and Management Policies" in the
Statement of Additional Information.
INVESTMENT CONSIDERATIONS AND RISKS
   
GENERAL -- The Fund's net asset value per share should be expected to
fluctuate. Investors should consider the Fund as a supplement to an overall
investment program and should invest only if they are willing to undertake
the risks involved. See "Investment Objective and Management Policies" in the
Statement of Additional Information for a further discussion of certain
risks.
    
EQUITY SECURITIES -- Equity securities fluctuate in value, often based on
factors unrelated to the value of the issuer of the securities, and such
fluctuations can be pronounced. Changes in the value of the Fund's
investments will result in changes in the value of its shares and thus the
Fund's total return to investors.
   
FOREIGN SECURITIES -- Since the stocks of some foreign issuers are included
in the Index, the Fund's portfolio may contain securities of such foreign
issuers which may subject the Fund to additional investment risks with
respect to those securities that are different in some respects from those
incurred by a fund which invests only in securities of domestic issuers. Such
risks include possible adverse political and economic developments, seizure
or nationalization of foreign deposits or adoption of governmental restrictions
which might adversely affect or restrict the payment of principle and
interest on the foreign securities to investors located outside the country
of the issuer, whether from currency blockage or otherwise.
    
   
USE OF DERIVATIVES -- The Fund may invest, to a limited extent, in
derivatives ("Derivatives"). These are financial instruments which derive
their performance, at least in part, from the performance of an underlying
asset or index. The Derivatives the Fund may use include stock index futures.
While Derivatives can be used effectively in furtherance of the Fund's
investment objective, under certain market conditions, they can increase the
volatility of the Fund's net asset value, decrease the liquidity of the
Fund's portfolio and make more difficult the accurate pricing of the Fund's
portfolio. See "Appendix _Investment Techniques _ Use of Derivatives" below
and " Investment Objective and Management Policies _ Management Policies _
Derivatives" in the Statement of Additional Information.
    
NON-DIVERSIFIED STATUS -- The classification of the Fund as a
"non-diversified" investment company means that the proportion of the Fund's
assets that may be invested in the securities of a single issuer is not
limited by the 1940 Act. A "diversified" investment company is required by
the 1940 Act generally, with respect to 75% of its total assets, to invest
not more than 5% of such assets in the securities of a single issuer. Since a
relatively high percentage of the Fund's assets may be invested in the
securities of a limited number of issuers, some of which may be within the
same economic sector, the Fund's portfolio may be more sensitive to the
changes in market value of a single issuer or industry. However, to meet
Federal tax requirements, at the close of each quarter the Fund may not have
more than 25% of its total assets invested in any one issuer and, with
respect to 50% of total assets, not more than 5% of its total assets invested
in any one issuer. These limitations do not apply to U.S. Government
securities.
                                    Page 5

SIMULTANEOUS INVESTMENTS -- Investment decisions for the Fund are made
independently from those of the other investment companies or accounts
advised by Dreyfus or Mellon Equity. If, however, such other investment
companies or accounts desire to invest in, or dispose of, the same securities
as the Fund, available investments or opportunities for sales will be
allocated equitably to each. In some cases, this procedure may adversely
affect the size of the position obtained for or disposed of by the Fund or
the price paid or received by the Fund.
MANAGEMENT OF THE FUND
   
ADVISERS -- Dreyfus, located at 200 Park Avenue, New York, New York 10166,
was formed in 1947 and serves as the Fund's manager. Dreyfus is a
wholly-owned subsidiary of Mellon Bank, N.A., which is a wholly-owned
subsidiary of Mellon Bank Corporation ("Mellon"). As of January 31, 1997,
Dreyfus managed or administered approximately $85 billion in assets for
approximately 1.7 million investor accounts nationwide.
    
        Dreyfus supervises and assists in the overall management of the
Fund's affairs under a Management Agreement with the Fund, subject to the
authority of the Fund's Board in accordance with Maryland law.
   
        Dreyfus has engaged Mellon Equity, located at 500 Grant Street,
Pittsburgh, Pennsylvania 15258, to serve as the Fund's index fund manager.
Mellon Equity, a registered investment adviser formed in 1957, is an indirect
wholly-owned subsidiary of Mellon and, thus, an affiliate of Dreyfus. As of
December 31, 1996, Mellon Equity and its employees managed approximately
$11.3 billion in assets and served as the investment adviser of 14 other
investment companies.
    
        Mellon Equity, subject to the supervision and approval of Dreyfus,
provides the day-to-day management of the Fund's investments, as well as
statistical information, under an Index Management Agreement with Dreyfus,
subject to the overall authority of the Fund's Board in accordance with
Maryland law.
   
        Mellon is a publicly owned multibank holding company incorporated
under Pennsylvania law in 1971 and registered under the Federal Bank Holding
Company Act of 1956, as amended. Mellon provides a comprehensive range of
financial products and services in domestic and selected international
markets. Mellon is among the twenty-five largest bank holding companies in
the United States based on total assets. Mellon's principal wholly-owned
subsidiaries are Mellon Bank, N.A., Mellon Bank (DE) National Association,
Mellon Bank (MD), The Boston Company, Inc., AFCO Credit Corporation and a
number of companies known as Mellon Financial Services Corporations. Through
its subsidiaries, including Dreyfus, Mellon managed more than $233 billion in
assets as of December 31, 1996, including approximately $86 billion in
proprietary mutual fund assets. As of December 31, 1996, Mellon, through
various subsidiaries, provided non-investment services, such as custodial or
administration services, for more than $1.046 trillion in assets, including
approximately $57 billion in mutual fund assets.
    
   
        For the fiscal year ended December 31, 1996, the Fund paid Dreyfus a
monthly management fee at the annual rate of .245 of 1% of the value of the
Fund's average daily net assets, and Dreyfus paid Mellon Equity an index
management fee at the annual rate of .095 of 1% of the value of the Fund's
average daily net assets. Under the Index Management Agreement, Mellon Equity
has agreed to pay for the provision of custody services to the Fund by Boston
Safe Deposit and Trust Company.
    
   
    
   
        The imposition of the Fund's management fee, as well as other
operating expenses, will have the effect of reducing investors' return and
will affect the Fund's ability to track the Index exactly. Dreyfus has
undertaken that, until such time as it gives shareholders at least 180 days
notice to the contrary, if in any fiscal year the aggregate expenses of the
Fund (excluding brokerage commissions, transaction fees and extraordinary
expenses) exceed .40 of 1% of the value of the Fund's average net assets for
the fiscal year, the Fund may deduct from the payment to be made to Dreyfus,
or Dreyfus will bear, such excess expense. In addition, from time to time,
Dreyfus may waive receipt of its fees and/or voluntarily assume certain
expenses of the Fund, which would have the effect of lowering the expense
ratio of the Fund and increasing yield to investors. The Fund will not pay
Dreyfus at a later time for any amounts Dreyfus may waive, nor will the Fund
reimburse Dreyfus for any amounts Dreyfus may assume.
    
   
        In allocating brokerage transactions, the Advisers seek to obtain the
best execution of orders at the most favorable net price. Subject to this
determination, the Advisers may consider, among other things, the  receipt of
research services and/or the sale of shares of the Fund or other funds
advised by Dreyfus or Mellon Equity as
                                    Page 6

factors in the selection of broker-dealers to execute portfolio transactions
for the Fund. See "Portfolio Transactions" in the Statement of Additional
Information.
    
   
        The Dreyfus Corporation, from time to time, may make payments from
its own assets to Participating Insurance Companies in connection with the
provision of certain administrative services to the Fund and/or to purchasers
of VA contracts or VLI policies.
    
   
DISTRIBUTOR -- The Fund's distributor is Premier Mutual Fund Services, Inc.
(the "Distributor"), located at 60 State Street, Boston, Massachusetts 02109.
The Distributor's ultimate parent is Boston Institutional Group, Inc.
    
TRANSFER AND DIVIDEND DISBURSING AGENT AND CUSTODIAN -- Dreyfus Transfer,
Inc., a wholly-owned subsidiary of Dreyfus, P.O. Box 9671, Providence, Rhode
Island 02940-9671, is the Fund's Transfer and Dividend Disbursing Agent (the
"Transfer Agent"). Boston Safe Deposit and Trust Company, an indirect
subsidiary of Mellon, One Boston Place, Boston, Massachusetts 02108, is the
Custodian of the Fund's investments.
                             HOW TO BUY SHARES
   
        FUND SHARES CURRENTLY ARE OFFERED ONLY TO SEPARATE ACCOUNTS OF
PARTICIPATING INSURANCE COMPANIES. INDIVIDUALS MAY NOT PLACE PURCHASE ORDERS
DIRECTLY WITH THE FUND.
    
   
        Separate accounts of the Participating Insurance Companies place
orders based on, among other things, the amount of premium payments to be
invested pursuant to VA contracts and VLI policies. See the prospectus of the
separate account of the applicable Participating Insurance Company for more
information on the purchase of Fund shares.
    
        If an order is received by the Fund or its agent by the close of
trading on the floor of the New York Stock Exchange (currently 4:00 p.m., New
York time) on a business day, Fund shares will be purchased at the net asset
value determined as of such close of trading on the day the order is
received. Otherwise, Fund shares will be purchased at the net asset value
determined as of the close of trading on the floor of the New York Stock
Exchange on the next business day.
        Fund shares are sold on a continuous basis. Net asset value per share
is determined as of the close of trading on the floor of the New York Stock
Exchange on each day the New York Stock Exchange is open for business. For
purposes of determining net asset value, futures contracts will be valued 15
minutes after the close of trading on the floor of the New York Stock
Exchange. Net asset value per share is computed by dividing the value of the
Fund's net assets (i.e., the value of its assets less liabilities) by the
total number of shares outstanding. The Fund's investments are valued based
on market value, or where market quotations are not readily available, based
on fair value as determined in good faith by the Fund's Board. For further
information regarding the methods employed in valuing the Fund's investments,
see "Determination of Net Asset Value" in the Statement of Additional
Information.
                           HOW TO REDEEM SHARES
   
        Fund shares may be redeemed at any time by the separate accounts of
the Participating Insurance Companies. INDIVIDUALS MAY NOT PLACE REDEMPTION
ORDERS DIRECTLY WITH THE FUND. When the Fund or its agent receives a request
in proper form by the close of trading on the floor of the New York Stock
Exchange (currently 4:00 p.m., New York time), the Fund will redeem the
shares at the net asset value determined as of the close of such trading on
the day the request is received. To maximize the Fund's ability to track the
Index, separate accounts of Participating Insurance Companies are urged to
transmit redemption requests so that they may be received by the Fund or its
agent prior to 12:00 noon, New York time, on the day upon which separate
accounts of Participating Insurance Companies want their redemption requests
to be effective. The value of the shares redeemed may be more or less than
their original cost, depending on the Fund's then-current net asset value. No
charges are imposed by the Fund when shares are redeemed.
    
        The Fund ordinarily will make payment for all shares redeemed within
seven days after receipt by the Transfer Agent of a redemption request in
proper form, except as provided by the rules of the Securities and Exchange
Commission.
                                    Page 7

        Should any conflict between VA contract holders and VLI policy
holders arise which would require that a substantial amount of net assets be
withdrawn, orderly portfolio management could be disrupted to the potential
detriment of such contract and policy holders.
                          SHAREHOLDER SERVICES PLAN
        The Fund has adopted a Shareholder Services Plan pursuant to which
the Fund reimburses Dreyfus Service Corporation, a wholly-owned subsidiary of
Dreyfus, an amount not to exceed an annual rate of .25 of 1% of the value of
the Fund's average daily net assets for certain allocated expenses with
respect to servicing and/or maintaining shareholder accounts.
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
        The Fund ordinarily declares and pays dividends from net investment
income quarterly, and automatically reinvests them in additional Fund shares
at net asset value or, at the shareholder's option, pays them in cash. The
Fund makes distributions from net realized securities gains, if any, once a
year, but may make distributions on a more frequent basis to comply with the
distribution requirements of the Internal Revenue Code of 1986, as amended
(the "Code"), in all events in a manner consistent with the provisions of the
1940 Act. The Fund will not make distributions from net realized securities
gains unless capital loss carryovers, if any, have been utilized or have
expired. If all shares in an account are redeemed at any time, all dividends
to which the shareholder is entitled will be paid along with the proceeds of
the redemption. An omnibus accountholder may indicate in a partial redemption
request that a portion of any accrued dividends to which such account is
entitled belongs to an underlying accountholder who has redeemed all shares
in his or her account, and such portion of the accrued dividends will be paid
to the accountholder along with the proceeds of the redemption. All expenses
are accrued daily and deducted before declaration of dividends to investors.
   
        Section 817(h) of the Code requires that the investments of a
segregated asset account of an insurance company be "adequately diversified''
as provided therein or in accordance with U.S. Treasury Regulations, in order
for the account to serve as the basis for VA contracts or VLI policies.
Section 817(h) and the U.S. Treasury Regulations issued thereunder provide
the manner in which a segregated asset account will treat investments in a
regulated investment company for purposes of the diversification requirements.
 If the Fund satisfies certain conditions, a segregated asset account owning
shares of the Fund will be treated as owning multiple investments consisting
of the account's proportionate share of each of the assets of the Fund. The
Fund intends to satisfy these conditions so that the shares of the Fund owned
by a segregated asset account of a Participating Insurance Company will be
treated as multiple investments. Further, the Fund intends to satisfy the
diversification standards prescribed under Section 817(h) for segregated
accounts. By meeting these and other requirements, the Participating
Insurance Companies, rather than VA contract holders or VLI policy holders,
should be subject to tax on distributions received with respect to Fund shares.
The tax treatment on distributions made to a Participating Insurance
Company will depend on the Participating Insurance Company's tax status.
    
   
        Notice as to the tax status of dividends and distributions will be
mailed to shareholders annually. Dividends derived from net investment
income, together with distributions of net realized short-term securities
gains, generally are taxable as ordinary income whether received in cash or
reinvested in additional Fund shares. Distributions from net realized
long-term securities gains generally are taxable as long-term capital gains
whether received in cash or reinvested in additional Fund shares. Since the
Fund's shareholders are the Participating Insurance Companies and their
separate accounts, no discussion is included herein as to the Federal income
tax consequences to VA contract holders and VLI policy holders. For
information concerning the Federal income tax consequences to such holders,
see the prospectus for such contract or policy.
    
   
        Management of the Fund believes that the Fund has qualified for the
fiscal year ended December 31, 1996 as a "regulated investment company" under
the Code. The Fund intends to continue to so qualify if such qualification is
in the best interest of its shareholders. Qualification as a regulated
investment company relieves the Fund of any liability for Federal income
taxes to the extent its earnings are distributed in accordance with
                                    Page 8

applicable provisions of the Code. The Fund is subject to a non-deductible 4%
excise tax, measured with respect to certain undistributed amounts of taxable
investment income and capital gains.
    
        Participating Insurance Companies should consult their tax advisers
regarding specific questions as to Federal, state or local taxes.
                            PERFORMANCE INFORMATION
        For the purpose of advertising, performance is calculated on the
basis of average annual total return and/or total return.
        Average annual total return is calculated pursuant to a standardized
formula which assumes that an investment in the Fund was purchased with an
initial payment of $1,000 and that the investment was redeemed at the end of
a stated period of time, after giving effect to the reinvestment of dividends
and distributions during the period. The return is expressed as a percentage
rate which, if applied on a compounded annual basis, would result in the
redeemable value of the investment at the end of the period. Advertisements
of the Fund's performance will include the Fund's average annual total return
for one, five and ten year periods, or for shorter time periods depending
upon the length of time during which the Fund has operated.
        Total return is computed on a per share basis and assumes the
reinvestment of dividends and distributions. Total return generally is
expressed as a percentage rate which is calculated by combining the income
and principal changes for a specified period and dividing by the net asset
value per share at the beginning of the period. Advertisements may include
the percentage rate of total return or may include the value of a
hypothetical investment at the end of the period which assumes the
application of the percentage rate of total return.
        Performance will vary from time to time and past results are not
necessarily representative of future results. Performance information, such
as that described above, may not provide a basis for comparison with other
investments or other investment companies using a different method of
calculating performance.
        The Fund's average annual total return and total return should not be
compared with other funds that offer their shares directly to the public
since the figures provided do not reflect charges of Participating Insurance
Companies. In addition, the Fund's total return should be distinguished from
the rate of return of a separate account or investment division of a separate
account of a Participating Insurance Company, which rate will reflect the
deduction of additional charges, including mortality and expense risk
charges, and therefore will be lower. VA contract holders and VLI policy
holders should consult the prospectus for such contract or policy.
        Comparative performance information may be used from time to time in
advertising or marketing the Fund's shares, including data from Standard &
Poor's 500 Composite Stock Price Index, Standard & Poor's MidCap 400 Index,
Lipper Analytical Services, Inc., the Dow Jones Industrial Average, Money
Magazine, Morningstar, Inc. and other industry publications. The Fund may
cite in its advertisements or in reports or other communications to
shareholders, historical performance of unmanaged indices as reported in
Ibbotson, Roger G. and Rex A. Sinquefield, Stocks, Bonds, Bills and Inflation
(SBBI), updated annually in the SBBI Yearbook, Ibbotson Associates, Chicago.
In its advertisements, the Fund also may cite the aggregate amount of assets
committed to index investing by pension funds and/or other institutional
investors, and may refer to or discuss then current or past economic or
financial conditions, developments or events.
                             GENERAL INFORMATION
        The Fund was incorporated under Maryland law on January 24, 1989, and
commenced operations on September 29, 1989. On May 1, 1994, the Fund, which
is incorporated under the name Dreyfus Life and Annuity Index Fund, Inc.,
began operating under the name Dreyfus Stock Index Fund. The Fund is
authorized to issue 200 million shares of Common Stock, par value $.001 per
share. Each share has one vote. In accordance with current law, the Fund
anticipates that a Participating Insurance Company issuing a VA contract or
VLI policy that participates in the Fund will request voting instructions
from contract and policy holders and will vote shares in proportion to the
voting instructions received. For further information on voting rights, see
the applicable prospectus of the Participating Insurance Company.
                                    Page 9

        Unless otherwise required by the 1940 Act, ordinarily it will not be
necessary for the Fund to hold annual meetings of shareholders. As a result,
Fund shareholders may not consider each year the election of Board members or
the appointment of auditors. However, pursuant to the Fund's By-Laws, the
holders of at least 10% of the shares outstanding and entitled to vote may
require the Fund to hold a special meeting of shareholders for purposes of
removing a Board member from office and the holders of at least 25% of such
shares may require the Fund to hold a special meeting of shareholders for any
other purpose. Fund shareholders may remove a Board member by the affirmative
vote of a majority of the Fund's outstanding voting shares. In addition, the
Fund's Board will call a meeting of shareholders for the purpose of electing
Board members if, at any time, less than a majority of the Board members then
holding office have been elected by shareholders.
        The Transfer Agent maintains a record of shareholder ownership and
sends confirmations and statements of account.
        Owners of policies and contracts issued by a Participating Insurance
Company for which shares of the Fund are an investment vehicle will receive
from the Participating Insurance Company unaudited semi-annual financial
statements and audited year-end financial statements certified by the Fund's
independent public accountants. Each report will show the investments owned
by the Fund and the market values thereof and will provide other information
about the Fund and its operations.
        Shareholder inquiries may be made by writing to the Fund at 144 Glenn
Curtiss Boulevard, Uniondale, New York 11566-0144, or by calling toll free
1-800-645-6561. In New York City, call 1-718-895-1206; outside the U.S. and
Canada, call 516-794-5452.

makes no representation or warranty, express or implied, to the owners of the
Fund or any member of the public regarding the advisability of investing in
securities generally or in the Fund particularly or the ability of the S&P
500 Index to track general stock market performance. S&P's only relationship

INVESTMENT TECHNIQUES
BORROWING MONEY -- The Fund is permitted to borrow money only for temporary
or emergency (not leveraging) purposes, in an amount up to 5% of the value of
its total assets (including the amount borrowed) valued at the lesser of cost
or market, less liabilities (not including the amount borrowed) at the time
the borrowing is made.
USE OF DERIVATIVES -- The Fund may invest in the types of Derivatives
enumerated under "Description of the Fund -- Investment Considerations and
Risks -- Use of Derivatives." These instruments and certain related risks are
described more specifically under "Investment Objective and Management
Policies -- Management Policies -- Derivatives" in the Statement of
Additional Information.
   
        Although the Fund will not be a commodity pool, certain Derivatives
subject the Fund to the rules of the Commodity Futures Trading Commission
which limit the extent to which the Fund can invest in such Derivatives. The
Fund may invest in stock index futures contracts for hedging purposes without
limit. However, the Fund may not invest in such contracts for other purposes
if the sum of the amount of initial margin deposits, other than for bona fide
hedging purposes, exceeds 5% of the liquidation value of the Fund's assets,
after taking into account unrealized profits and unrealized losses on such
contracts.
    
   
LENDING PORTFOLIO SECURITIES -- The Fund may lend securities from its
portfolio to brokers, dealers and other financial institutions needing to
borrow securities to complete certain transactions. The Fund continues to be
entitled to payments in amounts equal to the interest, dividends or other
distributions payable on the loaned securities which affords the Fund an
opportunity to earn interest on the amount of the loan and on the loaned
securities' collateral. Loans of portfolio securities may not exceed 30% of
the value of the Fund's total assets, and the Fund will receive collateral
consisting of cash, U.S. Government securities or irrevocable letters of
credit which will be maintained at all times in an amount equal to at least
100% of the current market value of the loaned securities. Such loans are
terminable by the Fund at any time upon specified notice. The Fund might
experience risk of loss if the institution with which it has engaged in a
portfolio loan transaction breaches its agreement with the Fund.
    
        NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATIONS OTHER THAN THOSE CONTAINED IN THIS PROSPECTUS AND IN THE
FUND'S OFFICIAL SALES LITERATURE IN CONNECTION WITH THE OFFER OF THE FUND'S
SHARES, AND, IF GIVEN OR MADE, SUCH OTHER INFORMATION OR REPRESENTATIONS MUST

          INVESTMENT OBJECTIVE AND MANAGEMENT POLICIES

     The following information supplements and should be read in conjunction
with the sections in the Fund's Prospectus entitled "Description of the
Fund" and "Appendix."

Portfolio Securities

     Money Market Instruments.  The Fund may invest, in the circumstances
described under "Description of the Fund - Management Policies" in the
Fund's Prospectus, in the following types of money market instruments.

U.S. Government Securities.  Securities issued or guaranteed by the U.S.
Government or its agencies or instrumentalities include U.S. Treasury
securities that differ in their interest rates, maturities and times of
issuance.  Some obligations issued or guaranteed by U.S. Government agencies
and instrumentalities are supported by the full faith and credit of the U.S.
Treasury; others by the right of the issuer to borrow from the Treasury;
others by discretionary authority of the U.S. Government to purchase certain
obligations from the agency or instrumentality; and others only by the
credit of the agency or instrumentality.  These securities bear fixed,
floating or variable rates of interest.  While the U.S. Government provides
financial support for such U.S. Government-sponsored agencies and
instrumentalities, no assurance can be given that it will always do so since
it is not so obligated by law.
   
Repurchase Agreements.  In a repurchase agreement, the Fund buys, and the
seller agrees to repurchase, a security at a mutually agreed upon time and
price (usually within seven days).  The repurchase agreement thereby
determines the yield during the purchaser's holding period, while the
seller's obligation to repurchase is secured by the value of the underlying
security.  The Fund's custodian or sub-custodian will have custody of, and
will hold in a segregated account, securities acquired by the Fund under a
repurchase agreement.  Repurchase agreements are considered by the staff of
the Securities and Exchange Commission to be loans by the Fund.  In an
attempt to reduce the risk of incurring a loss on a repurchase agreement,
the Fund will enter into repurchase agreements only with domestic banks with
total assets in excess of $1 billion, or primary government securities
dealers reporting to the Federal Reserve Bank of New York, with respect to
securities of the type in which the Fund may invest, and will require that
additional securities be deposited with it if the value of the securities
purchased should decrease below resale price.  Repurchase agreements could
involve risks in the event of a default or insolvency of the other party to
the agreement, including possible delays or restrictions upon the Fund's
ability to dispose of the underlying securities.
    
Bank Obligations.  The Fund may purchase certificates of deposit, time
deposits, bankers' acceptances and other short-term obligations issued by
domestic banks, foreign subsidiaries or foreign branches of domestic banks,
domestic and foreign branches of foreign banks, domestic savings and loan
associations and other banking institutions.  With respect to such
securities issued by foreign subsidiaries or foreign branches of domestic
banks, and domestic and foreign branches of foreign banks, the Fund may be
subject to additional investment risks that are different in some respects
from those incurred by a fund which invests only in debt obligations of U.S.
domestic issuers.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period
of time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time (in no event longer than seven
days) at a stated interest rate.

     Bankers' acceptances are credit instruments evidencing the obligation
of a bank to pay a draft drawn on it by a customer.  These instruments
reflect the obligation both of the bank and the drawer to pay the face
amount of the instruments upon maturity.  The other short-term obligations
may include uninsured, direct obligations bearing fixed, floating or
variable interest rates.

Commercial Paper.  Commercial paper consists of short-term, unsecured
promissory notes issued to finance short-term credit needs.  The commercial
paper purchased by the Fund will consist only of direct obligations which,
at the time of their purchase, are (a) rated at least Prime-1 by Moody's
Investors Service, Inc. ("Moody's") or A-1 by Standard & Poor's Ratings
Group ("S&P"), (b) issued by companies having an outstanding unsecured debt
issue currently rated at least Aa by Moody's or at least AA- by S&P, or (c)
if unrated, determined by the Advisers to be of comparable quality to those
rated obligations which may be purchased by the Fund.

Management Policies

     Lending Portfolio Securities.  In connection with its securities
lending transactions, the Fund may return to the borrower or a third party
which is unaffiliated with the Fund, and which is acting as a "placing
broker," a part of the interest earned from the investment of collateral
received for securities loaned.

     The Securities and Exchange Commission currently requires that the
following conditions must be met whenever portfolio securities are loaned:
(1) the Fund must receive at least 100% cash collateral from the borrower;
(2) the borrower must increase such collateral whenever the market value of
the securities rises above the level of such collateral; (3) the Fund must
be able to terminate the loan at any time; (4) the Fund must receive
reasonable interest on the loan, as well as any dividends, interest or other
distributions payable on the loaned securities, and any increase in market
value; (5) the Fund may pay only reasonable custodian fees in connection
with the loan; and (6) while voting rights on the loaned securities may pass
to the borrower, the Fund's Board must terminate the loan and regain the
right to vote the securities if a material event adversely affecting the
investment occurs.

     Derivatives.  The Fund may invest in Derivatives (as defined in the
Fund's Prospectus) in anticipation of taking a market position when, in the
opinion of the Advisers, available cash balances do not permit an
economically efficient trade in the cash market.  Derivatives may provide a
cheaper, quicker or more specifically focused way for the Fund to invest
than "traditional" securities would.

     Derivatives can be volatile and involve various types and degrees of
risk, depending upon the characteristics of the particular Derivative and
the portfolio as a whole.  Derivatives permit the Fund to increase or
decrease the level of risk, or change the character of the risk, to which
its portfolio is exposed in much the same way as the Fund can increase or
decrease the level of risk, or change the character of the risk, of its
portfolio by making investments in specific securities.

     Derivatives may entail investment exposures that are greater than their
cost would suggest, meaning that a small investment in Derivatives could
have a large potential impact on the Fund's performance.

     If the Fund invests in Derivatives at inappropriate times or judges
market conditions incorrectly, such investments may lower the Fund's return
or result in a loss.  The Fund also could experience losses if its
Derivatives were poorly correlated with its other investments, or if the
Fund were unable to liquidate its position because of an illiquid secondary
market.  The market for many Derivatives is, or suddenly can become,
illiquid.  Changes in liquidity may result in significant, rapid and
unpredictable changes in the prices for Derivatives.

Stock Index Futures.  A stock index future obligates the Fund to pay or
receive an amount of cash equal to a fixed dollar amount specified in the
futures contract multiplied by the difference between the settlement price
of the contract on the contract's last trading day and the value of the
index based on the stock prices of the securities that comprise it at the
opening of trading in such securities on the next business day.  The Fund
purchases and sells futures contracts on the stock index for which it can
obtain the best price with consideration also given to liquidity.

     Using futures in anticipation of market transactions involves certain
risks.  Although the Fund intends to purchase or sell futures contracts only
if there is an active market for such contracts, no assurance can be given
that a liquid market will exist for any particular contract at any
particular time.  In addition, the price of stock index futures may not
correlate perfectly with the movement in the stock index due to certain
market distortions.  First, all participants in the futures market are
subject to margin deposit and maintenance requirements.  Rather than meeting
additional margin deposit requirements, investors may close futures
contracts through offsetting transactions which would distort the normal
relationship between the index and futures markets.  Secondly, from the
point of view of speculators, the deposit requirements in the futures market
are less onerous than margin requirements in the securities market.
Therefore, increased participation by speculators in the futures market also
may cause temporary price distortions.  Because of the possibility of price
distortions in the futures market and the imperfect correlation between
movements in the stock index and movements in the price of stock index
futures, a correct forecast of general market trends still may not result in
a successful hedging transaction.

     In connection with its futures transactions, the Fund may be required
to establish and maintain at its custodian bank a segregated account
consisting of permissible liquid assets in an amount equal to the market
value of the underlying commodity less any amount deposited as margin.

Investment Restrictions

     The Fund has adopted the following investment restrictions as
fundamental policies, which cannot be changed without approval of the
holders of a majority (as defined in the Investment Company Act of 1940, as
amended (the "1940 Act")) of the Fund's outstanding voting shares.  The Fund
may not:
   
     1.   Purchase securities of any company having less than three years'
continuous operations (including operations of any predecessors) if such
purchase would cause the value of the Fund's investments in all such
companies to exceed 5% of the value of its total assets.
    
     2.   Purchase securities of closed-end investment companies, except (a)
in the open market where no commission other than the ordinary broker's
commission is paid, which purchases are limited to a maximum of (i) 3% of
the total outstanding voting stock of any one closed-end investment company,
(ii) 5% of the Fund's net assets with respect to the securities issued by
any one closed-end investment company and (iii) 10% of the Fund's net assets
in the aggregate, or (b) those received as part of a merger or
consolidation.  The Fund may not purchase the securities of open-end
investment companies other than itself.

     3.   Invest in commodities, except that the Fund may invest in futures
contracts as described in the Prospectus and Statement of Additional
Information.

     4.   Purchase, hold or deal in real estate, or oil and gas interests,
but the Fund may purchase and sell securities that are secured by real
estate or issued by companies that invest or deal in real estate.

     5.   Borrow money or pledge, mortgage or hypothecate its assets, except
as described in the Fund's Prospectus and the Statement of Additional
Information and in connection with entering into futures contracts.
Collateral arrangements with respect to initial or variation margin for
futures contracts will not be deemed to be pledges of the Fund's assets.
   
     6.   Lend any funds or other assets, except through the purchase of
debt securities, bankers' acceptances and commercial paper of corporations
and other entities.  However, the Fund may lend its portfolio securities in
an amount not to exceed 30% of the value of its total assets.  Any loans of
portfolio securities will be made according to guidelines established by the
Securities and Exchange Commission and the Fund's Board.
    
     7.   Act as an underwriter of securities of other issuers or purchase
securities subject to restrictions on disposition under the Securities Act
of 1933 (so-called "restricted securities").  The Fund may not enter into
repurchase agreements providing for settlement in more than seven days after
notice or purchase securities which are not readily marketable, if, in the
aggregate, more than 10% of the value of the Fund's net assets would be so
invested.  The Fund will not enter into time deposits maturing in more than
seven days and time deposits maturing from two business through seven
calendar days will not exceed 10% of the Fund's total assets.

     8.   Invest in the securities of a company for the purpose of
exercising management or control, but the Fund will vote the securities it
owns in its portfolio as a shareholder in accordance with its views.

     9.   Purchase, sell or write puts, calls or combinations thereof.

     10.  Invest more than 25% of its assets in investments in any
particular industry or industries (including banking), except to the extent
the Index also is so concentrated, provided that, when the Fund has adopted
a temporary defensive posture, there shall be no limitation on the purchase
of obligations issued or guaranteed by the U.S. Government, its agencies or
instrumentalities.

     In addition to the investment restrictions adopted as fundamental
policies set forth above, the Fund operates with certain non-fundamental
policies which may be changed by vote of a majority of the Board members at
any time.  The Fund may not:  (i) engage in arbitrage transactions,
(ii) purchase warrants (other than those acquired by the Fund in units or
attached to securities), (iii) sell securities short, but reserves the right
to sell securities short against the box, and (iv) invest more than 10% of
its total assets in the securities of any single issuer or invest in more
than 10% of the voting securities of any single issuer.  In addition, the
Fund intends to:  (i) comply with the diversification requirements under
Section 817(h) of the Internal Revenue Code of 1986, as amended (the
"Code"), and (ii) comply in all material respects with relevant insurance
laws and regulations applicable to investments of separate accounts of
Participating Insurance Companies.

     If a percentage restriction is adhered to at the time of investment, a
later change in percentage resulting from a change in values or assets will
not constitute a violation of such restriction.

     The Fund may make commitments more restrictive than the restrictions
listed above so as to permit the sale of Fund shares in certain states.
Should the Fund determine that a commitment is no longer in the best
interests of the Fund and its shareholders, the Fund reserves the right to
revoke the commitment by terminating the sale of Fund shares in the state
involved.

with the section in the Fund's Prospectus entitled "Management of the Fund."

     Management Agreement.  Dreyfus provides management services pursuant to
the Management Agreement (the "Management Agreement") dated November 13,
1995, with the Fund, which is subject (after May 14, 1997) to annual
approval by (i) the Fund's Board or (ii) vote of a majority (as defined in
the 1940 Act) of the outstanding voting securities of the Fund, provided
that in either event the continuance also is approved by a majority of the
Board members who are not "interested persons" (as defined in the 1940 Act)
of the Fund or Dreyfus by vote cast in person at a meeting called for the
purpose of voting on such approval.  The Management Agreement was approved
by shareholders on November 3, 1995 and was last approved by the Fund's
Board, including a majority of the Board members who are not "interested
persons" (as defined in the 1940 Act) of any party to the Management
Agreement, at a meeting held on August 9, 1995.  The Management Agreement is
terminable without penalty, on 60 days' notice, by the Fund's Board or by
vote of the holders of a majority of the Fund's shares, or, upon not less
than 90 days' notice, by Dreyfus.  The Management Agreement will terminate
automatically in the event of its assignment (as defined in the 1940 Act).

data processing, bookkeeping and internal auditing and certain other
required services to the Fund.  Dreyfus also may make such advertising and
promotional expenditures, using its own resources, as it from time to time
deems appropriate.

     Index Management Agreement.  Mellon Equity provides investment advisory
assistance and day-to-day management of the Fund's investments pursuant to
the Index Management Agreement (the "Index Management Agreement") dated
November 13, 1995 between Mellon Equity and Dreyfus.  The Index Management
Agreement is subject (after May 14, 1997) to annual approval by (i) the
Fund's Board or (ii) vote of a majority (as defined in the 1940 Act) of the
Fund's outstanding voting securities, provided that in either event the
continuance also is approved by a majority of the Fund's Board members who
are not "interested persons" (as defined in the 1940 Act) of the Fund or
Mellon Equity, by vote cast in person at a meeting called for the purpose of
voting on such approval.  The Index Management Agreement was approved by
shareholders on November 3, 1995, and was approved by the Fund's Board,
including a majority of Board members who are not "interested persons" of
any party to the Index Management Agreement, at a meeting held on August 9,
1995.  The Index Management Agreement is terminable without penalty (i) by
Dreyfus on 60 days' notice, (ii) by the Fund's Board or by vote of the
holders of a majority of the Fund's shares on 60 days' notice, or (iii) by
Mellon Equity on not less than 90 days' notice.  The Index Management
Agreement will terminate automatically in the event of its assignment (as
defined in the 1940 Act) or upon the termination of the Management Agreement
for any reason.

     The following persons are executive officers and/or directors of Mellon
Equity:  Phillip R. Roberts, Chairman of the Board; William P. Rydell,
President and Chief Executive Officer; and W. Keith Smith, Director.

     Mellon Equity provides day-to-day management of the Fund's investments
in accordance with the stated policies of the Fund, subject to the
supervision of Dreyfus and approval of the Fund's Board.  All purchases and
sales are reported for the Board's review at the meeting subsequent to such
transactions.  Mellon Equity has agreed to pay for the custody services
provided to the Fund by Boston Safe Deposit and Trust Company.

     Expenses.  All expenses incurred in the operation of the Fund are borne
by the Fund, except to the extent specifically assumed by Dreyfus and/or
Mellon Equity.  The expenses borne by the Fund include:  organizational
costs, taxes, interest, loan commitment fees, interest and distributions
paid on securities sold short, brokerage fees and commissions, if any, fees
of Board members who are not officers, directors, employees or holders of 5%
or more of the outstanding voting securities of Dreyfus or Mellon Equity or
any of their affiliates, Securities and Exchange Commission fees, state Blue
Sky qualification fees, advisory fees, transfer and dividend disbursing
agents' fees, certain insurance premiums, industry association fees, outside
auditing and legal expenses, costs of independent pricing services, costs of
maintaining the Fund's existence, costs attributable to investor services
(including, without limitation, telephone and personnel expenses), costs of
preparing and printing prospectuses and statements of additional information
for regulatory purposes and for distribution to existing shareholders, costs
of shareholder's reports and meetings, and any extraordinary expenses.
   
     As compensation for Dreyfus' services, the Fund has agreed to pay
Dreyfus a monthly fee at the annual rate of .245 of 1% of the value of the
Fund's average daily net assets.  As compensation for Mellon Equity's
services, Dreyfus has agreed to pay Mellon Equity a monthly fee at the
annual rate of .095 of 1% of the value of the Fund's average daily net
assets.  All fees and expenses are accrued daily and deducted before
declaration of dividends to shareholders.  For the period November 13, 1995
(effective date of the Management Agreement and Index Management Agreement)
through December 31, 1995 and for the fiscal year ended December 31, 1996,
the Fund paid Dreyfus management fees of $94,372 and $1,278,312,
respectively, and Dreyfus paid Mellon Equity index management fees of
$36,593 and $498,160, respectively.
    
   
     From April 4, 1990 to November 13, 1995, Wells Fargo Nikko Investment
Advisers ("WFNIA") served as the Fund's index fund manager.  Pursuant to
prior index management agreements with WFNIA, the Fund agreed to pay a
monthly fee at the annual rate of .15 of 1% of the value of the Fund's
average daily net assets.  For the fiscal year ended December 31, 1994 and
for the period January 1, 1995 through November 12, 1995 (termination date
of the prior index management agreement), the index management fees payable
to WFNIA amounted to $116,361 and $223,935, respectively, which fees were
reduced by $63,576 and $28,973, respectively, pursuant to undertakings by
WFNIA, resulting in net fees being paid to WFNIA of $52,785 in fiscal 1994
and $194,962 in fiscal 1995.
    
   
     Prior to November 13, 1995, Dreyfus served as the Fund's administrator
pursuant to an administration agreement with the Fund.  As compensation for
its administrative services, the Fund agreed to pay Dreyfus a monthly fee at
the annual rate of .15 of 1% of the value of the Fund's average daily net
assets.  For the fiscal year ended December 31, 1994 and for the period
January 1, 1995 through November 12, 1995 (termination date of the prior
administration agreement), the administration fees payable to Dreyfus
amounted to $116,361 and $223,934 respectively, which amounts were reduced
by $63,577 and $28,972, respectively pursuant to undertakings by Dreyfus,
resulting in net fees being paid to Dreyfus of $52,784 in fiscal 1994 and
$194,962 in fiscal 1995.
    
     Dreyfus (and to a limited extent, Mellon Equity) have agreed that if in
any fiscal year the aggregate expenses of the Fund (including fees pursuant
to the Management Agreement, but excluding taxes, brokerage, interest on
borrowings and, with the prior written consent of the necessary state
securities commissions, extraordinary expenses) exceed the expense
limitation of any state having jurisdiction over the Fund, the Fund may
deduct from the fees to be paid to Dreyfus, and Dreyfus may deduct from the
fees paid to Mellon Equity or Dreyfus and Mellon Equity will bear, such
excess expense in proportion to their management fee and index management
fee, to the extent required by state law.  Such deduction or payment, if
any, will be estimated daily and reconciled and effected or paid, as the
case may be, on a monthly basis.

     The aggregate fees payable to Dreyfus and Mellon Equity is not subject
to reduction as the value of the Fund's net assets increases.



                       PURCHASE OF SHARES

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "How to Buy Shares."

     The Distributor.  The Distributor serves as the Fund's distributor on a
best efforts basis pursuant to an agreement which is renewable annually.
The Distributor also acts as distributor for the other funds in the Dreyfus
Family of Funds and for certain other investment companies.
   
                   SHAREHOLDER SERVICES PLAN
    
     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Shareholder Services
Plan."

     The Fund has adopted a Shareholder Services Plan (the "Plan") pursuant
to which the Fund reimburses Dreyfus Service Corporation for certain
allocated expenses with respect to servicing and/or maintaining shareholder
accounts.

     A quarterly report of the amounts expended under the Plan, and the
purposes for which such expenditures were incurred, must be made to the
Fund's Board for its review.  In addition, the Plan provides that material
amendments of the Plan must be approved by the Board and by the Board
members who are not "interested persons" (as defined in the 1940 Act) of the
Fund and have no direct or indirect financial interest in the operation of
the Plan, by vote cast in person at a meeting called for the purpose of
considering such amendments.  The Plan is subject to annual approval by such
vote of the Board members cast in person at a meeting called for the purpose
of voting on the Plan.  The Plan is terminable at any time by vote of a
majority of the Board members who are not "interested persons" (as defined
in the 1940 Act) of the Fund and have no direct or indirect financial
interest in the operation of the Plan.
   
     For the fiscal year ended December 31, 1996, $9,218 was charged to the
Fund under the Plan.
    

                      REDEMPTION OF SHARES

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "How to Redeem Shares."

     Redemption Commitment.  The Fund has committed to pay in cash all
redemption requests by any shareholder of record, limited in amount during
any 90-day period to the lesser of $250,000 or 1% of the value of the Fund's
net assets at the beginning of such period.  Such commitment is irrevocable
without the prior approval of the Securities and Exchange Commission.  In
the case of requests for redemption in excess of such amount, the Fund's
Board reserves the right to make payments in whole or part in securities or
other assets of the Fund in case of an emergency or any time a cash
distribution would impair the liquidity of the Fund to the detriment of the
existing shareholders.  In such event, the securities would be valued in the
same manner as the Fund's portfolio is valued.  If the recipient sold such
securities, brokerage charges would be incurred.

     Suspension of Redemptions.  The right of redemption may be suspended or
the date of payment postponed (a) during any period when the New York Stock
Exchange is closed (other than customary weekend and holiday closings), (b)
when trading in the markets the Fund ordinarily utilizes is restricted, or
when an emergency exists as determined by the Securities and Exchange
Commission so that disposal of the Fund's investments or determination of
its net asset value is not reasonably practicable or (c) for such other
periods as the Securities and Exchange Commission by order may permit to
protect the Fund's shareholders.


                DETERMINATION OF NET ASSET VALUE

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled  "How to Buy Shares."

     Valuation of Portfolio Securities.  The Fund's portfolio securities are
valued at the last sale price on the securities exchange or national
securities market on which such securities are primarily traded.  Securities
not listed on an exchange or national securities market, or securities in
which there were no transactions, are valued at the average of the most
recent bid and asked prices.  Bid price is used when no asked price is
available.  Any securities or other assets for which recent market
quotations are not readily available are valued at fair value as determined
in good faith by the Fund's Board.  Expenses and fees, including the index
management and administration fees (reduced by the expense limitation, if
any), are accrued daily and taken into account for the purpose of
determining the net asset value of Fund shares.

     New York Stock Exchange Closings.  The holidays (as observed) on which
the New York Stock Exchange is closed currently are:  New Year's Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving and Christmas.


               DIVIDENDS, DISTRIBUTIONS AND TAXES

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Dividends, Distributions
and Taxes."
   
     Taxation of the Fund.  Management of the Fund believes that the Fund
qualified for the fiscal year ended December 31, 1996 as a "regulated
investment company" under the Code.  The Fund intends to continue to so
qualify so long as such qualification is in the best interests of its
shareholders.  Qualification as a regulated investment company relieves the
Fund from any liability for Federal income taxes to the extent its earnings
are distributed in accordance with the applicable provisions of the Code.
Among the requirements for such qualification is that less than 30% of the
Fund's gross income must be derived from the gain on the sale or other
disposition of securities held for less than three months.  The term
"regulated investment company" does not imply the supervision of management
or investment practices or policies by any government agency.
    
   
     If, however, the Fund does not qualify as a "regulated investment
company," it would be subject to the general rules governing the Federal
income taxation of corporations under the Code.  As such, the Fund's taxable
income could be subject to a maximum tax rate of 35% thereby reducing the
amount of cash available for distribution to shareholders.  Moreover,
distributions to shareholders would not be deductible in computing the
Fund's taxable income. Shareholders in receipt of distributions from the
Fund generally would be required to treat such amounts as ordinary dividend
income to the extent attributable to each such shareholder's share of the
Fund's current and accumulated earnings and profits.  Amounts received in
excess of the Fund's current and accumulated earnings and profits would
constitute a return of capital to the extent of the shareholder's basis in
Fund shares.  Any excess received over basis would constitute capital gain.
Certain corporate shareholders would be entitled to a dividends received
deduction under Section 243 of the Code to the extent amounts distributed
from the Fund constituted ordinary dividend income.
    
     Section 817(h) of the Code requires that the investments of a
segregated asset account of an insurance company be "adequately diversified"
as provided therein or in accordance with U.S. Treasury Regulations in order
for the account to serve as the basis for VA contracts or VLI policies.  The
Fund intends to comply with the applicable requirements so that the Fund's
investments are "adequately diversified" for this purpose.  Upon
satisfaction of these requirements, shares of the Fund owned by a segregated
asset account of a Participating Insurance Company will be treated as
multiple investments.

     If, however, the Fund were not to satisfy these conditions, a
segregated asset account of a Participating Insurance Company owning
shares of the Fund would be required to treat such shares as a single
investment asset (and, accordingly, would not be able to treat its
proportionate interest in the Fund's assets as being directly owned) for
purposes of determining whether the segregated asset account is
"adequately diversified" within the meaning of Section 817(h) of the Code.
This, in turn, would make it more difficult for any such segregated asset
account to satisfy the diversification standards of the Code.  If a
segregated asset account is not adequately diversified, it may not serve as
the basis for VA contracts or VLI policies.
   
     Ordinarily, gains and losses realized from portfolio transactions will
be treated as capital gain or loss.  In addition, all or a portion of the
gain realized from engaging in "conversion transactions" may be treated as
ordinary income under Section 1258.  "Conversion transactions" are defined
to include certain forward, futures, option and "straddle" transactions,
transactions marketed or sold to produce capital gains, or transactions
described in Treasury regulations to be issued in the future.
    
     Under Section 1256 of the Code, gain or loss realized by the Fund from
certain financial futures transactions will be treated as 60% long-term
capital gain or loss and 40% short-term capital gain or loss.  Gain or loss
will arise upon the exercise or lapse of such futures as well as from
closing transactions.  In addition, any such futures remaining unexercised
at the end of the Fund's taxable year will be treated as sold for their then
fair market value, resulting in additional gain or loss to the Fund
characterized in the manner described above.

     Offsetting positions held by the Fund involving futures may constitute
"straddles."  Straddles are defined to include "offsetting positions" in
actively traded personal property.  The tax treatment of straddles is
governed by Sections 1092 and 1258 of the Code, which, in certain
circumstances, overrides or modifies the provisions of Section 1256.  As
such, all or a portion of any short-or long-term capital gain from certain
"straddle" and/or conversion transactions may be recharacterized to ordinary
income.

     If a Fund were treated as entering into straddles by reason of its
futures transactions, such straddles could be characterized as "mixed
straddles" if the futures transactions comprising such straddles were
governed by Section 1256 of the Code.  The Fund may make one or more
elections with respect to "mixed straddles."  Depending upon which election
is made, if any, the results to the Fund may differ.  If no election is
made, to the extent the straddle rules apply to positions established by the
Fund, losses realized by the Fund will be deferred to the extent of
unrealized gain in any offsetting positions.  Moreover, as a result of the
straddle and the conversion transaction rules, short-term capital loss on
straddle positions may be recharacterized as long-term capital loss, and
long-term capital gain may be recharacterized as short-term capital gain or
ordinary income.

     Shareholder Taxation.  Since the shareholders of the Fund are the
separate accounts of Participating Insurance Companies, no discussion is
included herein as to the Federal income tax consequences at the level of
the holders of the VA contracts or VLI policies.  For information concerning
the Federal income tax consequences to such holders, see the prospectuses
for such VA contracts or VLI policies.


                     PORTFOLIO TRANSACTIONS

     The Advisers assume general supervision over placing orders on behalf
of the Fund for the purchase or sale of portfolio securities.  Allocation of
brokerage transactions, including their frequency, is made in the best
judgment of the Advisers and in a manner deemed fair and reasonable to
shareholders.  The primary consideration is prompt execution of orders at
the most favorable net price.  Brokers also are selected because of their
ability to handle special executions such as are involved in large block
trades or broad distributions, provided the primary consideration is met.
Portfolio turnover may vary from year to year, as well as within a year.
High turnover rates are likely to result in comparatively greater brokerage
expenses.  The overall reasonableness of brokerage commissions paid is
evaluated by the Advisers based upon their knowledge of available
information as to the general level of commissions paid by other
institutional investors for comparable services.

     For its portfolio securities transactions for the fiscal years ended
December 31, 1994, 1995 and 1996, the Fund paid total brokerage commissions
of $36,780, $43,661 and $116,347, respectively, none of which was paid to
the Distributor.  No spreads or concessions were paid by the Fund for such
fiscal years.


                    PERFORMANCE INFORMATION

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Performance
Information."
   
     The Fund's average annual total return for the 1, 5 and 7.258 year
periods ended December 31, 1996 was 22.54%, 14.64% and 13.69%, respectively.
Average annual total return is calculated by determining the ending
redeemable value of an investment purchased with a hypothetical $1,000
payment made at the beginning of the period (assuming the reinvestment of
dividends and distributions), dividing by the amount of the initial
investment, taking the "n"th root of the quotient (where "n" is the number
of years in the period) and subtracting 1 from the result.
    
   
     The Fund's total return for the period September 29, 1989 (commencement
of operations) through December 31, 1996 was 153.50%.  Total return is
calculated by subtracting the amount of the Fund's net asset value per share
at the beginning of a stated period from the net asset value per share at
the end of the period (after giving effect to the reinvestment of dividends
and distributions during the period), and dividing the result by the net
asset value per share at the beginning of the period.
    

                   INFORMATION ABOUT THE FUND

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "General Information."

                            APPENDIX
   
     Description of S&P A-1 Commercial Paper Rating:
    
     The rating A is the highest rating and is assigned by S&P to issues
that are regarded as having the greatest capacity for timely payment.
Issues in this category are delineated with the number 1, 2 or 3 to indicate
the relative degree of safety.  Paper rated A-1 indicates that the degree of
safety regarding timely payment is either overwhelming or very strong.
Those issues determined to possess overwhelming safety characteristics are
denoted with a plus (+) sign designation.
   
     Description of Moody's Prime-1 Commercial Paper Rating:
    
     The rating Prime-1 (P-1) is the highest commercial paper rating
assigned by Moody's.  Issuers of P-1 paper must have a superior capacity for
repayment of short-term promissory obligations, and ordinarily will be
evidenced by leading market positions in well established industries, high
rates of return on funds employed, conservative capitalization structures
with moderate reliance on debt and ample asset protection, broad margins in
earnings coverage of fixed financial charges and high internal cash
generation, and well established access to a range of financial markets and
assured sources of alternate liquidity.

Dreyfus Stock Index Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS

NOTE 1--Significant Accounting Policies:
  Dreyfus  Stock  Index Fund (the  "Fund") is  registered  under the  Investment
Company Act of 1940 ("Act") as a non-diversified  open-end management investment
company, that is intended to be a funding vehicle for variable annuity contracts
and variable life insurance  policies to be offered by the separate  accounts of
life  insurance  companies.  The  Fund's  investment  objective  is  to  provide
investment  results  that  correspond  to the  price and  yield  performance  of
publicly  traded  common  stocks as  represented  by the Standard and Poor's 500
Composite Stock Price Index. The Dreyfus  Corporation  ("Dreyfus") serves as the
Fund's manager and Mellon Equity Associates  ("Mellon Equity"),  an affiliate of
Dreyfus,  serves as the Fund's  index  manager.  Boston  Safe  Deposit and Trust
Company, an affiliate of Dreyfus,  is the Fund's custodian.  Dreyfus is a direct
subsidiary of Mellon Bank, N.A.  Premier Mutual Fund Services,  Inc. acts as the
distributor of the Fund's shares, which are sold without a sales charge.

  The Fund's  financial  statements  are prepared in accordance  with  generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

  (a)  Portfolio  valuation:  Investments  in  securities  (including  financial
futures) are valued at the last sales price on the securities  exchange on which
such securities are primarily  traded or at the last sales price on the national
securities  market.  Securities  not  listed  on an  exchange  or  the  national
securities  market,  or  securities  for which there were no  transactions,  are
valued at the average of the most recent bid and asked prices. Bid price is used
when no asked price is available.  Investments denominated in foreign currencies
are translated to U.S. dollars at the prevailing rates of exchange.

  (b) Securities transactions and investment income: Securities transactions are
recorded  on a  trade  date  basis.  Realized  gain  and  loss  from  securities
transactions  are  recorded on the  identified  cost basis.  Dividend  income is
recognized  on the  ex-dividend  date  and  interest  income,  including,  where
applicable,  amortization  of  discount on  investments,  is  recognized  on the
accrual basis.

  (c) Dividends to shareholders: Dividends are recorded on the ex-dividend date.
Dividends from investment income-net are declared and paid on a quarterly basis.
Dividends  from  net  realized  capital  gain  are  normally  declared  and paid
annually, but the Fund may make distributions on a more frequent basis to comply
with the distribution requirements of the Internal Revenue Code. This may result
in  distributions  that are in excess of investment  income-net on a fiscal year
basis.  To the extent that net  realized  capital  gain can be offset by capital
loss  carryovers,  if any, it is the policy of the Fund not to  distribute  such
gain.

  (d) Federal income taxes:  It is the policy of the Fund to continue to qualify
as a  regulated  investment  company,  if  such  qualification  is in  the  best
interests of its  shareholders,  by complying with the  provisions  available to
certain investment companies,  as defined in applicable sections of the Internal
Revenue Code, and to make  distributions of taxable income sufficient to relieve
it from  substantially all Federal income and excise taxes.

NOTE 2--Bank Line ofCredit:
  The Fund  participates  with other  Dreyfus  managed  funds in a $100  million
unsecured  line of credit  primarily to be utilized  for  temporary or emergency
purposes,  including  the financing of  redemptions.  Interest is charged to the
Fund at rates which are related to the Federal  Funds rate in effect at the time
of  borrowings.  For the period ended December 31, 1996, the Fund did not borrow
under the line of credit.

NOTES TO FINANCIAL STATEMENTS (continued)

NOTE 3--Management Fee and Other Transactions With Affiliates:
  (a) Pursuant to an Investment Advisory Agreement with Dreyfus,  the investment
advisory  fee is  computed  at the annual rate of .245 of 1% of the value of the
Fund's average daily net assets,  and is payable monthly.  Dreyfus has agreed to
pay Mellon  Equity,  a monthly fee at the annual rate of .095 of 1% of the value
of the Fund's average daily net assets.  Dreyfus has currently  undertaken  from
January 1, 1996 until December 31, 1996 and thereafter until such a time as they
give  shareholders  at least 180 days notice to the contrary that if in any full
fiscal year the Fund's aggregate expenses  (exclusive of brokerage  commissions,
transaction fees and extraordinary  expenses) exceed an annual rate of .40 of 1%
of the value of the Fund's  average  daily net assets,  the Fund may deduct from
the payments to be made to Dreyfus,  or Dreyfus will bear,  such excess expense.
There was no expense reim bursement for the period ended December 31, 1996.

  (b) Pursuant to the Fund's  Shareholder  Services  Plan,  the Fund  reimburses
Dreyfus Service Corporation, a wholly-owned subsidiary of Dreyfus, an amount not
to exceed an annual rate of .25 of 1% of the value of the Fund's  average  daily
net assets for certain  allocated  expenses  with  respect to  servicing  and/or
maintaining shareholder accounts. During the period ended December 31, 1996, the
Fund was charged an aggregate  of $9,218  pursuant to the  Shareholder  Services
Plan.

  The Fund compensates Dreyfus Transfer,  Inc., a wholly-owned subsidiary of the
Manager,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities to perform  transfer agency services for the Fund. Such  compensation
amounted to $362 during the period ended December 31, 1996.

  (c) Each  director  who is not an  "affiliated  person"  as defined in the Act
receives from the Fund an annual fee of $2,500 and an attendance fee of $500 per
meeting.  The  Chairman  of  the  Board  receives  an  additional  25%  of  such
compensation.

NOTE 4--Securities Transactions:
  (a) The  aggregate  amount of purchases  and sales of  investment  securities,
excluding  short-term  securities,  during the period  ended  December  31, 1996
amounted to $424,886,551 and $51,539,693, respectively.

  The Fund may invest in financial  futures  contracts in order to gain exposure
to or protect against changes in the market.  The Fund is exposed to market risk
as a result of changes in the value of the underlying financial instruments (see
the Statement of Financial  Futures).  Investments in financial  futures require
the Fund to "mark to market" on a daily basis,  which reflects the change in the
market  value of the contract at the close of each day's  trading.  Accordingly,
variation margin payments are received or made to reflect daily unrealized gains
or losses. When the contracts are closed, the Fund recognizes a realized gain or
loss. These investments require initial margin deposits with a custodian,  which
consist of cash or cash  equivalents,  up to  approximately  10% of the contract
amount.  The amount of these  deposits is determined by the exchange or Board of
Trade on which the contract is traded and is subject to change.  Contracts  open
at December 31, 1996 and their related  unrealized  market  depreciation are set
forth in the Statement of Financial Futures.

  (b)  At  December  31,  1996,  accumulated  net  unrealized   appreciation  on
investments  was  $114,124,770,  consisting  of  $121,757,907  gross  unrealized
appreciation and $7,633,137 gross unrealized depreciation.

  At December 31, 1996, the cost of investments  for Federal income tax purposes
was substantially the same as the cost for financial reporting purposes (see the
Statement of Investments).

   We  conducted  our audits in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
December 31, 1996, by  correspondence  with the custodian and brokers.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.
   In our opinion, the financial statements and financial highlights referred to
above  present  fairly,  in all material  respects,  the  financial  position of
Dreyfus Stock Index Fund as of December 31, 1996, the results of its operations,
the  changes in its net assets,  and the  financial  highlights  for the periods
referred to above, in conformity with generally accepted accounting principles.
