TO OUR SHAREHOLDERS,

      During the first quarter of 1999,  Treasuries  continued the trend towards
higher yields that began in 1998. Seasonal factors such as the Japanese year end
and the first quarter refunding  combined with strong economic data early in the
first quarter pushed rates higher.  Subsequently,  the yield curve illustrated a
steeper bias.

      Although evidence suggests that the economy continues to expand at a rapid
pace,  there are few signs of  accelerating  inflation  pressures.  The Producer
Price Index ("PPI") fell 0.4% during February  following a 0.5% rise in January,
while the Consumer Price Index ("CPI") rose a modest 0.1% for the third straight
month.  But even more  encouraging  was the  insignificant  0.1% rise in average
hourly earnings. Despite continued tight labor market conditions; wage increases
have remained fairly modest.

      In the aftermath of a weaker than expected  employment  report,  continued
benign core PPI and a surprising  50 basis point  European  Central Bank ("ECB")
interest  rate cut,  bond rates have  dropped more than 22 basis points over the
past weeks and currently stand at their lowest levels since February. Whether we
are able to sustain and extend these gains  depends upon the  significance  of a
new catalyst occurrence,  whether it be further deceleration of price pressures,
an equity market correction,  a revival of global financial distress or economic
data released sharply below consensus.

      Economic  statistics have been market friendly and have led forecasters to
revise  their  first  quarter  estimate  of Gross  Domestic  Product  ("GDP") to
approximately  3.2%  versus a  previously  predicted  4.0%.  The most recent PPI
release  illustrating core rates of inflation unchanged continues to support the
market's solid growth, low inflation  condition.  However,  after the release of
March's Retail Sales and CPI,  strong figures  boosted GDP estimates once again.
The increase of 0.2% in Retail Sales was below  expectations.  However,  a sharp
upward revision to the January and February figures pointed to strong growth and
low  inflation.   Overall,   consumer   spending  remains  robust  and  personal
consumption expenditures are strong, adding support to the economy.

      With regard to the Federal Reserve's  outlook on monetary policy,  the Fed
sees no  accelerating  price  inflation  despite the growing  levels of business
activity  and very tight labor  markets.  This was  signaled  during  February's
Humphrey  Hawkins  testimony.  With strong  economic  growth,  very low rates of
unemployment and the absence of any build up on inflation,  the Fed is likely to
hold monetary policy steady.

INVESTMENT RESULTS

      For the  twelve-month  period  ended  March 31,  1999,  the  Gabelli  U.S.
Treasury  Money Market  Fund's (the "Fund")  total return was 4.71%.  The Lipper
U.S.  Treasury  Money  Market  Average had a total return of 4.58% over the same
period.  The Lipper  average  reflects the average  performance  of mutual funds
classified in this particular  category.  The Fund's 7-day  annualized yield and
30-day annualized yield on March 31, 1999 were 4.30% and 4.23%, respectively.

      For the  five-year  period ended March 31,  1999,  the Fund's total return
averaged  4.95%  versus an average  annual  total return of 4.74% for the Lipper
U.S.  Treasury Money Market Average.  Since inception on October 1, 1992 through
March 31, 1999,  the Fund had an average  annual  total  return of 4.46%.  As of
March 31, 1999,  shareholders  total 6,023 and net assets are $398 million.  The
Fund  maintained  a stable  net asset  value of $1.00 per share  throughout  the
period.

Subsequent Event

      On February 9, 1999, the Adviser  reorganized its operations and corporate
structure by transferring a portion of its assets and liabilities to a successor
adviser,  Gabelli Funds,  LLC, which is wholly owned by Gabelli Asset Management
Inc., a newly  formed  publicly  traded  company that is 80% owned by the former
Adviser.  Counsel to the former Adviser has concluded that the ownership  change
does not  constitute an assignment as defined by the  Investment  Company Act of
1940, as amended.

MINIMUM INITIAL INVESTMENT - $10,000

      The Fund's minimum initial investment is $10,000. However, shareholders of
any of the Gabelli  Funds may invest in the Fund with an initial  investment  of
$3,000.  IRAs,  retirement accounts and custodial accounts for minors require an
initial  investment of only $1,000. The Fund provides check writing and exchange
privileges and continues to offer these  services at no charge to  shareholders.
The Fund's  expenses  are  voluntarily  capped at 0.30% of average  net  assets,
making it one of the most attractive U.S. Treasury-only money market funds. With
dividends  that are exempt from state and local income taxes in all states,  the
Fund is an excellent vehicle in which to store idle cash.

PAST  PERFORMANCE IS NO GUARANTEE OF FUTURE  RESULTS.  Total returns and average
annual returns, which reflect changes in investment income, are net of expenses.
Investment returns and yields will fluctuate.  An investment in The Gabelli U.S.
Treasury  Money  Market  Fund is  neither  insured  nor  guaranteed  by the U.S.
Government or the Federal Deposit Insurance Corporation. Although the Fund seeks
to  preserve  the value of an  investment  at $1.00 per  share,  there can be no
assurance  that the Fund will maintain a stable $1.00 per share net asset value,
so it is possible to lose money by investing in the Fund. The Fund's  prospectus
contains more complete information,  including fees and expenses. The prospectus
should be read  carefully  before  investing  or  sending  money.  If the Fund's
expenses  had not been  capped,  the Fund's  7-day  annualized  yield and 30-day
annualized yield would have been 4.19% and 4.12%, respectively.

THE GABELLI U.S. TREASURY MONEY MARKET FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
================================================================================

1.  DESCRIPTION.  The Gabelli U.S.  Treasury  Money Market Fund (the "Fund"),  a
series of The Gabelli Money Market Funds (the "Trust"), was organized on May 21,
1992  as  a  Delaware  business  trust.  The  Fund  is a  diversified,  open-end
management  investment  company  registered under the Investment  Company Act of
1940, as amended (the "1940 Act"). The Fund's primary  objective is high current
income  consistent with the  preservation  of principal and liquidity.  The Fund
commenced investment operations on October 1, 1992.

2. SIGNIFICANT  ACCOUNTING POLICIES.  The preparation of financial statements in
accordance with generally accepted accounting  principles requires management to
make estimates and assumptions  that affect the reported amounts and disclosures
in the financial  statements.  Actual results could differ from those estimates.
The following is a summary of significant  accounting  policies  followed by the
Fund in the preparation of its financial statements.

SECURITY VALUATION. Investments are valued at amortized cost (which approximates
market value) whereby a portfolio  instrument is valued at cost and any discount
or premium is amortized on a constant basis to the maturity of the instrument.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME.  Securities  transactions  are
accounted  for on the  trade  date  with  realized  gain or loss on  investments
determined  by using the  identified  cost method.  Interest  income  (including
amortization of premium and accretion of discount) is recorded as earned.

DIVIDENDS  AND  DISTRIBUTIONS.   Dividends  from  investment  income  (including
realized  capital  gains  and  losses)  are  declared  daily  and paid  monthly.
Distributions of long term capital gains, if any, are paid annually.

PROVISION  FOR INCOME  TAXES.  The Fund has qualified and intends to continue to
qualify as a regulated  investment  company  under  Subchapter M of the Internal
Revenue Code of 1986, as amended. As a result, a Federal income tax provision is
not required.

3. AGREEMENTS WITH AFFILIATED  PARTIES.  The Trust has entered into a management
agreement (the "Management  Agreement") with Gabelli Funds, LLC (the "Manager"),
which  provides  that the Trust will pay the Manager a fee,  computed  daily and
paid  monthly,  at the  annual  rate of 0.30  percent of the value of the Fund's
average  daily net assets.  In accordance  with the  Management  Agreement,  the
Manager  provides a  continuous  investment  program  for the Fund's  portfolio,
oversees the  administration  of all aspects of the Fund's  business and affairs
and pays the  compensation  of all Officers and Trustees of the Fund who are its
affiliates.  To the extent  necessary,  the  Manager  has  undertaken  to assume
certain  expenses  of the Trust so that the total  expenses  do not exceed  0.30
percent of the Fund's  average daily net assets.  For the six months ended March
31, 1999, the Manager voluntarily waived management fees of $149,176.
