EX-99.77E LEGAL

SUB-ITEM 77E: LEGAL PROCEEDINGS

Since February 2004, Federated and related entities
(collectively, "Federated") have been named as
defendants in several lawsuits, that were
consolidated into a single action in the United States
District Court for the Western District of
Pennsylvania, alleging excessive advisory fees
involving one of the Federated-sponsored mutual
funds.  Without admitting the validity of any claim,
Federated reached a final settlement with the
Plaintiffs in these cases in April 2011.

EX-99.77B ACCT LTTR

Report of Independent Registered Public
Accounting Firm

To the Shareholders and Board of Directors of
Federated Municipal Securities Fund, Inc.:

In planning and performing our audit of the
financial statements of Federated Municipal
Securities Fund, Inc. (the "Fund") as of and for the
year ended March 31, 2012, in accordance with the
standards of the Public Company Accounting
Oversight Board (United States), we considered the
Fund's internal control over financial reporting,
including controls over safeguarding securities, as a
basis for designing our auditing procedures for the
purpose of expressing our opinion on the financial
statements and to comply with the requirements of
Form N-SAR, but not for the purpose of expressing
an opinion on the effectiveness of the Fund's
internal control over financial reporting.
Accordingly, we express no such opinion.

The management of the Fund is responsible for
establishing and maintaining effective internal
control over financial reporting. In fulfilling this
responsibility, estimates and judgments by
management are required to assess the expected
benefits and related costs of controls. A company's
internal control over financial reporting is a process
designed to provide reasonable assurance regarding
the reliability of financial reporting and the
preparation of financial statements for external
purposes in accordance with generally accepted
accounting principles.  A company's internal control
over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of
records that,  in reasonable detail, accurately and
fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary
to permit preparation of financial statements in
accordance with generally accepted accounting
principles, and that receipts and expenditures of the
company are being made only in accordance with
authorizations of management and directors of the
company; and (3) provide reasonable assurance
regarding prevention or timely detection of
unauthorized acquisition, use or disposition of a
company's assets that could have a material effect
on the financial statements.

Because of its inherent limitations, internal control
over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation
of effectiveness to future periods are subject to the
risk that controls may become inadequate because
of changes in conditions, or that the degree of
compliance with the policies or procedures may
deteriorate.

A deficiency in internal control over financial
reporting exists when the design or operation of a
control does not allow management or employees, in
the normal course of performing their assigned
functions, to prevent or detect misstatements on a
timely basis.  A material weakness is a deficiency, or
a combination of deficiencies, in internal control
over financial reporting, such that there is a
reasonable possibility that a material misstatement
of the company's annual or interim financial
statements will not be prevented or detected on a
timely basis.



Our consideration of the Fund's internal control
over financial reporting was for the limited purpose
described in the first paragraph and would not
necessarily disclose all deficiencies in internal
control that might be material weaknesses under
standards established by the Public Company
Accounting Oversight Board (United States).
However, we noted no deficiencies in the Fund's
internal control over financial reporting and its
operation, including controls over safeguarding
securities, that we consider to be a material
weakness as defined above as of March 31, 2012.

This report is intended solely for the information
and use of management and the Board of Directors
of the Fund and the Securities and Exchange
Commission and is not intended to be and should
not be used by anyone other than these specified
parties.
