        This statement amends the statement on Schedule 13D dated March 30,
1998, as amended on may 26, 1998 ("Schedule 13D"), previously filed by Markel
Corporation, a Virginia corporation ("Markel"), relating to the common stock,
$.01 par value per share ("Common Stock"), of Gryphon Holdings, Inc., a Delaware
corporation ("Gryphon" or the "Issuer"). Defined terms used herein and not
otherwise defined shall have the meaning set forth in the Schedule 13D.

ITEM 3.        SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      The aggregate cost for the acquisition of the additional 130,000 shares of
common stock of Gryphon reported herein was $2,010,625 and was paid for out of
Markel's working capital.

ITEM 4.        PURPOSE OF TRANSACTION.

Item 4 of the Schedule 13D is supplemented by the following:

      On May 29, 1998 and July 22, 1998 Markel received regulatory approval in
the states of California and Pennsylvania, respectively, which allow Markel to
proceed with its proposed purchase of up to 19.9% of Gryphon's outstanding
shares of Common Stock. Having previously filed a Disclaimer of Control with the
State of Connecticut, Markel purchased additional shares of Gryphon on July 23
and July 27, 1998. The approvals in California and Pennsylvania and the
Disclaimer in Connecticut are all conditioned upon Markel not controlling the
management or affairs of Gryphon. Should Markel change its plans or intentions
with respect to Gryphon it might be precluded from purchasing additional shares
without further regulatory approval. In addition, the Disclaimer filed in
Connecticut only constitutes a rebuttal of the statutory presumption of control
which exists when any person or entity exceeds ten percent ownership of an
insurance entity subject to the Connecticut Insurance Holding Company Act. The
Connecticut Department of Insurance may disallow the Disclaimer after notice and
an opportunity for hearing. Should the Connecticut Department of Insurance take
such action Markel could be precluded from making additional purchases or be
ordered to divest some of the Shares unless further regulatory filings were made
and approved. In addition to filings required under State insurance laws, Markel
could be required to make a filing and wait for the expiration or early
termination of applicable waiting periods under the Hart Scott Rodino Antitrust
Improvements Act. Such filing would generally be required before Markel acquired
more than $15 million or 15% of the outstanding shares of Common stock of
Gryphon.

      Markel acquired the Shares for the purpose of investment. Markel intends
to continue to monitor its investment and review Gryphon's business affairs and
financial position. Based on such review, as well as general economic and
industry conditions existing at the time, Markel may consider from time to time
various alternative courses of action and may discuss with Gryphon's Board ways
in which Gryphon's shareholder value may be increased. Markel may also have
discussions with Gryphon's Board of Directors, management and/or other
shareholders of Gryphon concerning (i) the acquisition or disposition of shares
of Gryphon Common Stock; (ii) Gryphon's charter, bylaws, shareholder rights plan
and other instruments and/or actions which may impede the acquisition of control
of Gryphon; and (iii) Gryphon's current and future business plans, prospects and
management. Markel may also seek to acquire additional shares of Common Stock
through open market purchases, privately negotiated transactions or otherwise or
it may seek to dispose of some or all of the Shares. Except as described above
or in the Schedule 13D, Markel does not currently have any plans or proposals
which relate to or would result in any of the actions or transactions specified
in clauses (a) though (j) of Item 4 of Schedule 13D. However, Markel reserves
the right at any time to formulate other plans and purposes regarding its Shares
or the Issuer.

ITEM 5.        INTEREST IN SECURITIES OF THE ISSUER.

      (a) Markel is the holder of 791,250 shares (the "Shares") of the Common
Stock, which represents approximately 11.7% of the Issuer's outstanding Common
Stock.

      (b) See Cover Pages, Items 7, 8, 9 and 10.

      (c) During the last 60 days, Markel made the following purchases and sales
of shares of Common Stock in open market transactions on the NASDAQ Stock
Market:

Purchase Date            Shares           Price per Share
7/28/98                  50,000            15.4375
7/22/98                  60,000            15.4375
7/27/98                  20,000            15.625

      (d)   None

      After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.



Dated: July 28, 1998                       /s/ STEVEN A. MARKEL
