Statement of Additional Information, dated February 1, 2000,
of Seligman Pennsylvania Municipal Fund Series, Inc. (the "Fund")
Effective August 11, 2000, the following disclosure (a) is added at the end

-- Custodian" on page 30 of the Fund's Statement of Additional Information:

From time to time, reference may be made in advertisements, sales literature or
other promotional material (collectively, "Promotional Material") to performance
information, including mutual fund rankings prepared by independent reporting
services which monitor the performance of mutual funds, including but not
limited to Lipper Analytical Services, Inc. and Morningstar, Inc. In calculating
the total return of the Fund's Class A, Class B, Class C, and Class D shares,
the Lipper analysis assumes investment of all dividends and distributions paid,
but does not take into account applicable sales charges. Morningstar's rankings
are calculated using a fund's average annual returns for a certain period and a
risk factor that reflects a fund's performance relative to three-month Treasury
Bill monthly returns. Morningstar's ratings range from five stars (highest) to
one star (lowest) and represent Morningstar's assessment of the historical risk
level and total return of a fund for 3-, 5-, and 10-year periods and, on an
overall basis, based on weighted-average of those periods. Ratings are not
absolute and do not represent future performance results.
The Fund's Promotional Material may disclose (i) the top ten holdings included
in the Fund's portfolio holdings, (ii) market sectors and statistical data
describing portfolio composition, (iii) discussions of general economic or
financial principals, (iv) discussions of general economic trends, (v)
descriptions of investment strategies for the Fund (vi) descriptions or
comparisons of various savings and investment products, which may not include
the Fund and (vii) comparisons of investment products (including the Fund) with
relevant market or industry indices or appropriate benchmarks. The Fund may also
include calculations, such as hypothetical compounding examples, which describe
hypothetical investment results. Such performance examples will be based on an
express set of assumptions and are not indicative of the future performance of
the Fund.
From time to time, the Fund's Promotional Materials may portray the historical
returns of various asset classes. Such presentations will typically compare the
average annual rates of return of inflation, U.S. Treasury bills, bonds,
large-cap stocks, and small-cap stocks. There are important differences between
each of these investments that should be considered in viewing any such
comparison. The market value of stocks will fluctuate with market conditions,
and small-stock prices generally will fluctuate more than large-stock prices.
Stocks are generally more volatile than bonds. In return for this volatility,
stocks have generally performed better than bonds or cash over time. Bond prices
generally will fluctuate inversely with interest rates and other market
conditions, and the prices of bonds with longer maturities generally will
fluctuate more than those of shorter-maturity bonds. Interest rates for bonds
may be fixed at the time of issuance, and payment of principal and interest may
be guaranteed by the issuer and, in the case of U.S. Treasury obligations,
backed by the full faith and credit of the U.S. Treasury.
The Fund may also refer in Promotional Material to selections from editorials or
articles about the Fund, including reprints of comments, listings and columns in
the financial and other press, the sources of which include BARRON'S, BUSINESS
WEEK, CDA/WIESENBERGER MUTUAL FUNDS INVESTMENT REPORT, CHRISTIAN SCIENCE
MONITOR, FINANCIAL PLANNING, FINANCIAL TIMES, FINANCIAL WORLD, FORBES, FORTUNE,

AND WORLD REPORT, WORTH MAGAZINE, WASHINGTON POST and YOUR MONEY.
The Fund's Promotional Material may make reference to the Fund's "Beta,"
"Standard Deviation," or "Alpha." Beta measures the volatility of the Fund, as
compared to that of the overall market. Standard deviation measures how widely
the Fund's performance has varied from its average performance, and is an
indicator of the Fund's potential for volatility. Alpha measures the difference
between the returns of the Fund and the returns of the market, adjusted for
volatility.
