        The Statement on Schedule 13D dated February 28, 1995, as previously
amended by Amendment No. 1 (which was a Schedule 14D-1 filed by Public Storage,
Inc. on July 26, 1996), Amendment No. 2 (which was Amendment No. 2 to the
Schedule 14D-1 filed by Public Storage, Inc. on September 10, 1996) and
Amendment No. 3 dated June 2, 1998 (as amended, the "Schedule 13D") filed by
Public Storage, Inc., formerly known as Storage Equities, Inc., relating to the
units of limited partnership interest (the "Units") of PS Partners, Ltd., a
California limited partnership (the "Issuer"), is amended by this Amendment No.
4 as set forth below. Capitalized terms that are not defined herein have the
meanings assigned to those terms in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Compensation
        ------------------------------------------------

        Item 3 of the Schedule 13D is supplemented as follows:

        On September 14, 1998, PSI, through a wholly-owned subsidiary, acquired
all of the 20,018 Units that were not previously owned by PSI. PSI's acquisition
of the 20,018 Units was accomplished through the merger (the "Merger") of PS
Partners Merger Co., Inc., a wholly-owned, second-tier subsidiary of PSI, into
the Issuer. The consideration issued by PSI in the Merger to the holders of the
20,018 Units (the "Public Limited Partners") consisted of approximately
$6,276,539 in cash and approximately 316,595 shares of Common Stock of PSI
("PSI Common Stock"). The cash consideration was paid by PSI from its working
capital.

Item 4. Purpose of Transaction
        ----------------------

        Item 4 of the Schedule 13D is supplemented as follows:

        Pursuant to the Merger, each of the 20,018 Units held by the Public
Limited Partners was converted into the right to receive cash or PSI Common
Stock. Based upon the elections made by the Public Limited Partners, PSI paid to
the Public Limited Partners an aggregate of approximately $6,276,539 in cash and
approximately 316,595 shares of PSI Common Stock. As a result of the Merger, (i)
PSI, through a wholly-owned subsidiary, owns all of the 66,000 Units in the
Partnership and (ii) PSI and B. Wayne Hughes retain their general partner
interests in the Partnership, and the Partnership remains in existence.

Item 5. Interest in Securities of the Issuer
        ------------------------------------

        Item 5 of the Schedule 13D is supplemented as follows:

        As of September 14, 1998, the effective date of the Merger, PSI owned
66,000 Units, which constitute 100% of the total number of Units outstanding.

        PSI has the sole power to vote and the sole power to dispose of the
66,000 Units owned by it. These 66,000 Units are held of record by SEI Arlington
Acquisition Corporation, a wholly-owned subsidiary of PSI.

        During the period commencing July 21, 1998 (i.e., after the filing of
Amendment No. 3 to the Schedule 13D) and ending September 14, 1998, PSI acquired
20,018 Units on September 14, 1998 pursuant to the Merger for an aggregate
consideration paid by PSI to the Public Limited Partners of approximately
$6,276,539 in cash and approximately 316,595 shares of PSI Common Stock.
