Dear Shareholder:


     We are pleased to provide you with the semi-annual report for the Zenix
Income Fund Inc. ("Fund") for the period ended September 30, 1997. Over the past
six months the Fund paid income dividends totaling $0.37 per common share.
During September 1997, the Fund raised its monthly income dividend to $0.063
from $0.061 per common share. The table below shows the annualized distribution
rate and six-month total return for the Fund based on its September 30, 1997 net
asset value ("NAV") per share and its New York Stock Exchange ("NYSE") closing
price.

</TABLE>

     The Fund generated a total return on NAV of 14.80% for the six-month period
ended September 30, 1997. The Fund outperformed the six-month average total
return for closed-end high yield funds of 11.50% for the same time period, as
reported by Lipper Analytical Services, Inc. ("Lipper"), largely due to the
Fund's use of leverage. (Lipper is an independent fund-tracking organization.) A
full discussion of the past six-month's economic and market conditions as well
as the investment strategy employed by the Fund during this time follows.

*This distribution rate assumes monthly dividends at the current rate of $0.063
per share for twelve months.

Market and Economic Overview

     The U.S. bond markets have generated respectable total returns over the
past six months with interest rates modestly lower so far in 1997. The high
yield bond market generated the strongest total returns in the domestic fixed
income arena as a result of both strong technical market conditions as well as
very positive fundamental conditions.

     Despite a considerable amount of new high yield bond issuance, there
continues to be significant demand from both institutional investors and retail
mutual funds. We have seen a record amount of new issuance (i.e., more than $90
billion) during the first nine months of this year and we expect this trend to
continue over the remainder of the year.

     There has been more than adequate demand to absorb the heavy new issue
supply. Increasing amounts of capital are flowing into the high yield market
from a variety of sources. The open-end high yield mutual funds have had over
$15 billion of cash inflows over the first nine months of 1997. More
importantly, the high yield market has continued to broaden and mature into a
more widely accepted investment alternative among more traditional institutional
investors. Pension funds are allocating larger percentages of their investment
portfolios to the high yield bond market. For example, the State of Florida
recently allocated $900 million of its pension assets to the high yield bond
market.

     During the past twelve months, there has been a meaningful increase in the
number of structured transactions incorporating high yield securities, which has
coincided with the increased investor demand for high yield securities. In the
past two years, a number of institutions, particularly insurance companies and
institutional money managers, have begun creating Collateralized Bond
Obligations ("CBOs") which use high yield securities as collateral. These
instruments are similar to Collateralized Mortgage Obligations ("CMOs") in
structure except they utilize high yield bonds instead of mortgage pass through
securities as their collateral. The CBOs sponsor not only receives a management
fee to manage the CBOs portfolio, but also takes an equity stake in the CBOs to
enhance returns even further. Given the intense demand for current yield over
the past year from many bond investors, there has been a significant increase in
the creation of CBOs. Put simply, the amount of capital being deployed into the
high yield market has risen to record levels.

- --------------------------------------------------------------------------------

     Given record investor demand and with the significant amount of capital
invested into the market, many high yield bonds have appreciated to fully valued
levels. For example, yield premiums over U.S. Treasuries have narrowed
approximately 100 basis points tighter than their historical averages. In
addition to the above technical factors, there are a number of positive
fundamental factors affecting the valuations of high yield bonds. Economic
conditions remain generally supportive with moderate growth and low inflation.
The stock market, with its higher valuations, has enabled a number of high yield
companies to issue stock to further bolster their balance sheets. In addition,
the banking system remains highly liquid, allowing it to accommodate many high
yield borrowers. Consequently, high yield bond default rates have been at the
low end of their historical range, at approximately 1.5% per year so far during
1997. As long as the overall economic and market conditions remain relatively
favorable, we believe high yield bond spreads should remain at the narrow end of
their historical range.

     Because of these positive fundamental factors, we do not believe the high
yield market is becoming increasingly speculative. However, we are naturally
becoming more sensitive to the possibility of disappointment and
underperformance among select individual issues. This has happened in the stock
market throughout the year. Given the high valuation levels of many financial
markets, we will continue to be more selective and cautious with respect to our
investments.

Portfolio Strategy

     Little has changed in the Fund since our last quarterly report. In this
moderate growth environment, we still expect the stronger high yield companies
to outperform and these companies tend to be in industries that stand to benefit
from new technology. We continue to find a number of attractive opportunities in
the telecommunications, media, cable TV and oil and natural gas industries, and
the Fund remains heavily weighted in these areas. Some of the issues that we
continue to favor include Time Warner, Cablevision Systems Corp., Nextel
Communications Inc., Rogers Cablesystems, Teleport Communications, Pride
Petroleum and Parker Drilling to name a few. All of these companies are
generating improving results either through increased market share and/or
improved internal cost controls.

     We firmly believe that over a full economic cycle the better quality
high-yield issues offer superior risk-adjusted returns and lower default risk
relative to lower-quality issues. We continue to maintain a meaningful
percentage of stronger BB-rated issues in the Fund. We are also maintaining an
intermediate average maturity in order to limit the Fund's interest rate
sensitivity. Considering the trend toward greater industry competition and
little pricing power in most sectors of the U.S. economy, we believe our prudent
and conservative approach to high yield bond investing should generate
consistent positive returns for shareholders over a full economic cycle. We
therefore will continue to avoid sectors of the economy that are not growing
fast or are facing intense industry competition, such as general retailers and
restaurants.

Market Outlook

     We remain optimistic about the total return prospects for the high yield
market for the remainder of 1997. At the very least, we expect a narrow trading
range for general interest rates over the fourth quarter, especially if U.S.
economic activity remains moderate and inflation stays subdued. We still believe
the U.S. economy could grow more slowly over the next several months with modest
inflation. Given our expectations, we have focused on maintaining sound credit
quality in the Fund.

     In closing, thank you for investing in the Zenix Income Fund Inc. We look
forward to continuing to help you pursue your investment goals. If you have any
questions about your investment in the Fund, please call First Data Investor

================================================================================

All ratings are by Standard & Poor's Ratings Service ("Standard & Poor's"),
except those identified by an asterisk (*) are rated by Moody's Investors
Service, Inc. ("Moody's"). The definitions of the applicable rating symbols are
set forth below:

Standard & Poor's -- Ratings from "BBB" to "CCC" may be modified by the addition
of a plus (+) or minus (-) sign to show relative standings within the major
rating categories.

BBB    --   Bonds rated "BBB" are regarded as having an adequate  capacity to 
            pay interest and repay  principal.  Whereas they normally exhibit 
            adequate protection parameters, adverse economic conditions or 
            changing circumstances, are more likely to lead to a weakened 
            capacity to pay interest and repay principal for bonds in this 
            category than in higher rated categories.

BB     --   Bonds rated "BB" have less near-term vulnerability to default
            than other speculative issues. However, it faces major ongoing
            uncertainties or exposure to adverse business, financial, or
            economic conditions which could lead to inadequate capacity to
            meet timely interest and principal payments.

B      --   Bonds rated "B" have a greater vulnerability to default but
            currently have the capacity to meet interest and principal
            payments. Adverse business, financial, or economic conditions will
            likely impair capacity or willingness to pay interest and repay
            principal. The "B" rating category is also used for debt,
            subordinated to senior debt, that is assigned an actual or implied
            "BB" or "BB-" rating.

CCC    --   Bonds rated "CCC" have a currently identifiable vulnerability
            to default, and are dependent upon favorable business, financial,
            and economic conditions to meet timely payment of interest and
            repayment of principal. In the event of adverse business,
            financial, or economic conditions, it is not likely to have the
            capacity to pay interest and repay principal. The "CCC" rating
            category is also used for debt, subordinated to senior debt, that
            is assigned an actual or implied "B" or "B-" rating.

Moody's -- Numerical modifiers 1, 2 and 3 may be applied to each generic rating
from "Baa" to "B," where 1 is the highest and 3 the lowest ranking within its
generic category. 

Baa    --   Bonds that are rated "Baa" are considered as medium grade 
            obligations, i.e., they are neither highly protected nor poorly 
            secured. Interest payments and principal security appear adequate 
            for the present but certain protective elements may be lacking or
            may be characteristically unreliable over any great length of 
            time. Such bonds lack outstanding investment characteristics and 
            in fact have speculative characteristics as well.

Ba     --   Bonds that are rated "Ba" are judged to have speculative
            elements; their future cannot be considered as well assured. Often
            the protection of interest and principal payments may be very
            moderate and thereby not well safeguarded during both good and bad
            time over the future. Uncertainty of position characterizes bonds
            in this class.

B      --   Bonds that are rated "B" generally lack characteristics of
            desirable investments. Assurance of interest and principal
            payments or of maintenance of other terms of the contract over any
            long period of time may be small.

NR     --   Indicates that the bond is not rated by Standard & Poor's or
            Moody's.

     1.   Significant Accounting Policies

     Zenix Income Fund Inc. ("Fund"), a Maryland corporation, is registered
under the Investment Company Act of 1940, as amended, as a diversified,
closed-end management investment company.

     The significant accounting policies followed by the Fund are: (a) security
transactions are accounted for on trade date; (b) securities traded in the
over-the-counter market, including listed securities for which the primary
market is believed to be over-the-counter, are valued at the mean between the
most recently quoted bid and ask prices provided by the principal market makers;
any security for which the primary market is an exchange is valued at the last
sale price on such exchange on the day of valuation or, if there was no sale on
such day, at the last bid price quoted. Securities and assets for which market
quotations are not readily available are valued at fair value as determined in
good faith by or under the direction of the Board of Directors of the Fund
including references to valuations of other securities which are considered
comparable in quality, interest rate and maturity; (c) securities maturing
within 60 days are valued at cost plus accreted discount, or minus amortized
premium, which approximates value; (d) the accounting records of the Fund are
maintained in U.S. dollars. All assets and liabilities denominated in foreign
currencies are translated into U.S. dollars based on the rate of exchange of
such currencies against U.S. dollars on the date of valuation. Purchases and
sales of securities, and income and expenses are translated at the rate of
exchange quoted on the respective date that such transactions are recorded.
Differences between income or expense amounts recorded and collected or paid are
adjusted when reported by the custodian bank; (e) dividend income is recorded on
the ex-dividend date and interest income is recorded on an accrual basis; (f)
gains or losses on the sale of securities are calculated by using the specific
identification method; (g) dividends and distributions to shareholders are
recorded monthly by the Fund on the ex-dividend date for the shareholders of
Common Stock based on net investment income. The holders of the 7.00% Cumulative
Preferred Stock shall be entitled to receive dividends when, as and if declared
by the Board of Directors of the Fund out of funds legally available to
shareholders at a rate of 7.00% per annum, payable semi-annually on June 15 and
December 15; (h) the net asset value of the Fund's Common Stock is

================================================================================

determined no less frequently than the close of business on the Fund's last
business day of each week (generally Friday). It is determined by dividing the
value of the net assets available to Common Stock by the total number of shares
of Common Stock outstanding. For the purpose of determining the net asset value
per share of the Common Stock, the value of the Fund's net assets shall be
deemed to equal the value for the Fund's assets less (1) the Fund's liabilities
(including the outstanding principal amount on the bank loan), (2) the aggregate
liquidation value (i.e., $1,000 per outstanding share) of the 7.00% Cumulative
Redeemable Preferred Stock and (3) accumulated and unpaid dividends on the
outstanding Cumulative Redeemable Preferred Stock issue; (i) the Fund intends to
comply with the requirements of the Internal Revenue Code of 1986, as amended,
pertaining to regulated investment companies and to make distributions of
taxable income sufficient to relieve it from substantially all Federal income
and excise taxes; (j) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. At March 31, 1997, reclassifications
were made to the Fund's capital accounts to reflect permanent book/tax
differences and income and gains available for distributions under income tax
regulations. Accordingly, a portion of accumulated net realized loss amounting
to $67,822 was reclassified to paid-in-capital. Net investment income, net
realized gains and net assets were not affected by this change; and (k)
estimates and assumptions are required to be made regarding assets, liabilities
and changes in net assets resulting from operations when financial statements
are prepared. Changes in the economic environment, financial markets and any
other parameters used in determining these estimates could cause actual results
to differ.

     2.   Advisory Agreement and Transactions with Affiliated Persons

     Smith Barney Mutual Funds Management Inc. ("SBMFM"), a subsidiary of Smith
Barney Holdings Inc. ("SBH"), through its Greenwich Street Advisors division,
acts as investment advisor to the Fund. The Fund pays SBMFM a management fee
calculated at an annual rate of 0.50% of the average daily net assets. This fee
is calculated daily and paid monthly.

================================================================================

     SBMFM also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets. This fee
is calculated daily and paid monthly.

     All officers and one Director of the Fund are employees of Smith Barney
Inc.

     4.   Cash Flow Information

     The Fund invests in securities and distributes dividends from net
investment income and net realized gains. These activities are reported in the
Statements of Changes in Net Assets. Information on cash payments is presented
in the Statement of Cash Flows. Accounting practices that do not affect
reporting activities on a cash basis include unrealized gains or losses on
investment securities.

     5.   Repurchase Agreements

     The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day) at
an agreed upon higher repurchase price. The Fund

requires continual maintenance of the market value of the collateral in amounts
at least equal to the repurchase price.

     6.   Cumulative Redeemable Preferred Stock

     On March 16, 1993, the Fund issued 30,000 shares of 7.00% Cumulative
Preferred Stock, which will be redeemed in full on April 15, 2000, at a price
equal to $1,000 per share, plus accumulated and unpaid dividends. On March 31,
1994, 220,000 shares of $0.01 par value 7.00% Cumulative Preferred Stock were
authorized but remained unissued. Cumulative undeclared dividends on the
outstanding Preferred Stock amounted to $624,243 at September 30, 1997.

     Moody's Investors Service, Inc. and Standard & Poor's Ratings Service have
reconfirmed their respective Aa3 and AA+ ratings of the Fund's 7% Cumulative
Preferred Stock.

     7.   Bank Loan

     The Fund has a $30,000,000 line of credit with PNC Bank, N.A. Interest on
the loan can be paid based on 30-, 60- or 90-day periods as elected by the Fund.
The interest on the loan is currently calculated at the federal funds rate plus
40 basis points. The line of credit expires on July 18, 1998. Interest expense
related to the loan for the six months ended September 30, 1997 was $915,200.

     8.   Common Stock

     At September 30, 1997, the Fund had 250,000,000 shares of common stock
authorized with a par value of $0.01 per share.

     9.   Capital Loss Carryforward

     As of March 31, 1997, the Fund had, for Federal income tax purposes,
capital loss carryforwards of approximately $32,003,000 available to offset
future realized capital gains, if any. To the extent that these carryforward
losses are used to offset capital gains, it is probable that the gains so offset

     10.  Asset Maintenance Requirement

     The Fund is required to maintain certain asset coverages with respect to
the Cumulative Preferred Stock (of at least 200%). If the Fund fails to maintain
these requirements as of the last business day of a month and does not cure such
failure by the last business day of the following month, the Fund is required to
redeem certain of the Cumulative Preferred Stock in order to meet these
requirements. Additionally, failure to meet the foregoing asset requirements
would restrict the Fund's ability to pay dividends.

     11.  Restricted Securities

     Certain of the Fund's Investments are valued at the direction of the Fund's
Board of Directors; these securities are restricted as to resale and have been
valued in good faith, taking into consideration the appropriate economic,
financial and other pertinent available information pertaining to the restricted
securities. The table below shows the security valued by the Fund's Board of

                                                      Dividend Reinvestment Plan
                                                                     (unaudited)
================================================================================

     Under the Fund's Dividend Reinvestment Plan ("Plan"), a shareholder whose
Common Stock is registered in his own name will have all distributions
reinvested automatically by First Data Investor Services Group, Inc. ("First
Data"), as agent under the Plan, unless the shareholder elects to receive cash.
Distributions with respect to shares registered in the name of a broker-dealer
or other nominee (that is, in "street name") will be reinvested by the broker or
nominee in additional Common Stock under the Plan, but only if the service is
provided by the broker or nominee, and the broker or nominee makes an election
on behalf of the shareholder to participate in the Plan. A shareholder who holds
Common Stock registered in the name of a broker or other nominee may not be able
to transfer the Common Stock to another broker or nominee and continue to
participate in the Plan. Investors who own Common Stock registered in street
name should consult their broker or nominee for details regarding reinvestment.

     The number of shares of Common Stock distributed to participants in the
Plan in lieu of a cash dividend is determined in the following manner. Whenever
the market price of the Fund's Common Stock is equal to or exceeds 98% of net
asset value per share, participants will be issued shares of Common Stock valued
at the greater of (i) 98% of net asset value per share or (ii) 95% of the then
current market price. If 98% of net asset value per share of Common Stock at the
time of valuation exceeds the market price of the Common Stock, First Data will
buy shares of the Fund's Common Stock on the open market, on the New York Stock
Exchange or elsewhere, as soon as practicable after the record date of the
dividend or distribution, until it has expended for such purchases all of the
cash that would otherwise be payable to the participants. The number of
purchased shares that will then be credited to the participant's account will be
based on the average per share purchase price of the shares so purchased,
including brokerage commissions. If First Data commences purchases in the open
market and the market price of the shares subsequently exceeds 98% of net asset
value before the completion of the purchases, First Data will attempt to
terminate purchases in the open market and cause the Fund to issue the remaining
dividend or distribution in shares at 98% of net asset value per share. In this
case, the number of shares of Common Stock received by the participant will be
based on the weighted average of prices

                                                          (unaudited)(continued)

paid for shares purchased in the open market and the price at which the Fund
issues the remaining shares.

     Plan participants are not subject to any charge for reinvesting dividends
or capital gains distributions. Each Plan participant will, however, bear a
proportionate share of brokerage commissions incurred with respect to First
Data's open market purchases of shares of Common Stock in connection with the
reinvestment of dividends or capital gains distributions. For the six months
ended September 30, 1997, no such brokerage commissions were incurred.

     The automatic reinvestment of dividends and capital gains distributions
will not relieve Plan participants of any income tax that may be payable on the
dividends or capital gains distributions. A participant in the Plan will be
treated for Federal income tax purposes as having received, on the dividend
payment date, a dividend or distribution in an amount equal to the cash that the
participant could have received instead of shares of Common Stock.

     A shareholder may terminate participation in the Plan at any time by
notifying First Data in writing. A termination will be effective immediately if
notice is received by First Data not less than 10 days before any dividend or
distribution record date. Otherwise, the termination will be effective, and only
with respect to any subsequent dividends or distributions, on the first trading
day after the dividend or distribution has been credited to the participant's
account in additional shares of Common Stock of the Fund. Upon termination
according to a participant's instructions, First Data will either (a) issue
