The Gabelli Convertible and Income Securities Fund Inc.
One Corporate Center
Rye, New York 10580-1422


Ladies and Gentlemen:

We have acted as special Maryland counsel to The Gabelli Convertible and
Income Securities Fund Inc., a Maryland corporation (the "Company"), in
connection with the registration of (i) 1,000,000 shares of the Company's
Series B Cumulative Preferred Stock, liquidation preference $25.00 per share,
$0.001 par value per share (the "Series B Preferred") and (ii) 1,000 shares of
the Company's Series C Auction Rate Cumulative Preferred Stock, liquidation
preference $25,000 per share, $0.001 par value per share (the "Series C
Auction Rate Preferred") on its Registration Statement on Form N-2, (the
"Registration Statement") filed by the Company with the Securities and
Exchange Commission under the Securities Act of 1933 and the Investment
Company Act of 1940.

We have examined the Registration Statement, including the exhibits thereto,
and such other documents, corporate records, laws and regulations, as we have
deemed necessary for the purposes of giving the opinions set forth in this
opinion letter. We have relied as to certain factual matters on information
obtained from public officials, officers of the Company and other sources
believed by us to be responsible. Based upon that examination and subject to
the assumptions and qualifications set forth herein, we are of the opinion
that:

1. The Company is a duly incorporated and validly existing under the laws of
the State of Maryland.

2. The Series B Preferred and the Series C Auction Rate Preferred have been
duly authorized by the Company's Board of Directors, and when the Shares have
been issued and sold as contemplated by the Registration Statement and
consideration therefor received by the Company, such shares will be legally
issued, fully paid and nonassessable.

We express no opinion with respect to the laws of, or the effect or
applicability of the laws of, any jurisdiction other than the laws of the
State of Maryland.
