DREYFUS MASSACHUSETTS MUNICIPAL MONEY MARKET FUND
Supplement to Statement of Additional Information
Dated April 15, 1993
The following information supplements and supersedes any contrary
information contained in the section in the Fund's Statement of Additional
Information captioned "Redemption of Fund Shares--Redemption by Wire or
Telephone" and describes a new telephone redemption privilege:
Wire Redemption Privilege. An investor may request by wire or
telephone that redemption proceeds (minimum $1,000) be wired to the
investor's account at a bank which is a member of the Federal Reserve
System, or a correspondent bank if the investor's bank is not a member. An
investor may direct that redemption proceeds be paid by check (maximum
$150,000 per day) made out to the owners of record and mailed to the
investor's address. Redemption proceeds of less than $1,000 will be paid
automatically by check. Holders of jointly registered Fund or bank
accounts may have redemption proceeds of only up to $250,000 wired within
any 30-day period. The Fund reserves the right to refuse any redemption
request, including requests made shortly after a change of address, and may
limit the amount involved or the number of such requests.
Telephone Redemption Privilege. An investor may redeem Fund shares
(maximum $150,000 per day) by telephone if the investor has checked the
appropriate box on the Fund's Account Application or has filed an Optional
Services Form with the Transfer Agent. The redemption proceeds will be
paid by check and mailed to the investor's address. An investor may
telephone redemption instructions by calling 1-800-221-4060 or, if the
investor is calling from overseas, 1-401-455-3306. The Fund reserves the
right to refuse any request made by telephone, including requests made
shortly after a change of address, and may limit the amount involved or the
number of telephone redemption requests. This Privilege may be modified or
terminated at any time by the Transfer Agent or the Fund. Shares for which
certificates have been issued are not eligible for this Privilege.
