Supplement, dated September 24, 1999, to the
Statement of Additional Information, dated June 1, 1999,
of Seligman Pennsyvlvania Municipal Fund Series (the "Fund")
The following supersedes the information appearing in the third full
paragraph of page 3 of the Fund's Statement of Additional Information.
On September 16, 1999, the Fund's Board of Directors eliminated the
non-fundamental policy which prohibited the Fund, with respect to 75% of the
value of its assets, from purchasing any revenue bonds if, as a result of such
purchase, more than 5% of the Fund's assets would be invested in the revenue
bonds of a single issuer. However, the Fund remains subject to a fundamental
policy which prohibits the Fund, with respect to 50% of the value of its total
assets, from purchasing the securities of any one issuer if, as a result of
such purchase, more than 5% of the Fund's total assets (at market value) would
be invested in the securities of a single issuer (except that this limitation
does not apply to obligations issued or guaranteed by the US Government or its
agencies or instrumentalities).
