Item 1.   Security and Issuer
          This Amendment No. 1 to Schedule 13D on Southwest Gas
Corporation (the "Issuer") is being filed on behalf of the
undersigned to amend the Schedule 13D, as amended (the "Schedule
13D") which was originally filed on November 13, 1995.  Unless
otherwise indicated, all capitalized terms used herein but not
defined herein shall have the same meaning as set forth in the
Schedule 13D.

Item 2.   Identity and Background
          This statement is being filed by Mario J. Gabelli ("Mr.
Gabelli") and various entities which he directly or indirectly
controls or for which he acts as chief investment officer.  These
entities, except for Lynch Corporation ("Lynch"), Spinnaker
Industries, Incorporated ("Spinnaker"), Western New Mexico
Telephone Company ("Western New Mexico"), Entoleter, Inc.
("Entoleter"),  Lynch Telecommunications Corporation ("Lynch
Telecom"), Lynch Telephone Corporation ("Lynch Telephone") and
Inter-Community Telephone Company ("Inter-Community") (collective-
ly, "Lynch and its affiliates"), engage in various aspects of the
securities business, primarily as investment adviser to various
institutional and individual clients, including registered
investment companies and pension plans, as broker/dealer and as
general partner of various private investment partnerships. 
Certain of these entities may also make investments for their own
accounts. 
          The foregoing persons in the aggregate often own benefi-
cially more than 5% of a class of equity securities of a particular
issuer.  Although several of the foregoing persons are treated as
institutional investors for purposes of reporting their beneficial
ownership on the short-form Schedule 13G, the holdings of those who
do not qualify as institutional investors may exceed the 1%
threshold presented for filing on Schedule 13D or implementation of
their investment philosophy may from time to time require action
which could be viewed as not completely passive.  In order to avoid
any question as to whether their beneficial ownership is being
reported on the proper form and in order to provide greater
investment flexibility and administrative uniformity, these persons
have decided to file their beneficial ownership reports on the more
detailed Schedule 13D form rather than on the short-form Schedule
13G and thereby to provide more expansive disclosure than may be
necessary. 
          (a), (b) and (c) - This statement is being filed by one
or more of the following persons: Gabelli Funds, Inc. ("GFI"),
GAMCO Investors, Inc. ("GAMCO"), Gabelli Securities, Inc. ("GSI"),
Gabelli & Company, Inc. ("Gabelli & Company"), Gabelli Performance
Partnership L.P. ("GPP"), GLI, Inc. ("GLI"), Gabelli Associates
Fund ("Gabelli Associates"), Gabelli Associates Limited ("GAL"),
Gabelli & Company, Inc. Profit Sharing Plan (the "Plan"), Gabelli
International Limited ("GIL"), Gabelli International II Limited
("GIL II"), Gabelli International Gold Fund Limited ("GIGFL"), ALCE
Partners, L.P. ("ALCE"), Gabelli Multimedia Partners, L.P.
("Multimedia Partners"), Gabelli Asset Management Company Interna-
tional Advisory Services Ltd. ("GIASL"), Mr. Gabelli, Lynch,
Spinnaker, Western New Mexico, Entoleter, Lynch Telecom, Lynch
Telephone and Inter-Community. Those of the foregoing persons

          (d) and (e) -  On December 8, 1994, the SEC instituted
and simultaneously accepted offers for the settlement of an
administrative proceeding against Gabelli & Company and GAMCO.  The
order instituting the proceeding included a finding, which Gabelli

to implement and maintain policies and procedures reasonably
designed to prevent the misuse of material, nonpublic information
by not sepecifically addressing the special circumstances that
arose from their affiliation with Lynch Corporation, a public
company.  To resolve this matter, Gabelli & Company and GAMCO
agreed to cease and desist from violating Section 15(f) of the 1934
Act and Section 204A of the Advisers Act, respectively.  They
further agreed to each pay a civil penalty in the amount of
$50,000, and to retain, and adopt the recommendations of, an
independant consultant regarding their Section 15(f) and Section
204A policies and procedures.  
          On December 13, 1991, the Virginia State Corporation
Commission entered an order of settlement in final disposition of
matters arising from an allegation that GAMCO had transacted
business in Virginia as an investment adviser without having been
registered as such under Virginia Code Section 13.1-504A or an
exemption therefrom.  GAMCO consented to the entry of the order
without admitting or denying the allegation and without a hearing. 
The terms of the order provide that GAMCO would pay a fine and
costs totalling fifty-five thousand dollars and would not transact
business in Virginia as an investment adviser unless it was
registered as such under section 13.1-504A or was exempt from
registration.  
     (f) - Reference is made to Schedule I hereto.
