                                   ABSTRACT

       The Parkes-MIT-NRAO (PMN) southern survey was made with the NRAO
    4.85 GHz seven-beam receiver on the Parkes 64 m telescope during 1990
    June, and maps covering the Omega = 2.5 sr declination band -88 deg <
    Dec. < -37 deg were contructed from the survey scans.  We present a
    catalog of 15,045 discrete sources with angular sizes phi <~ 15 arcmin
    and stronger than S ~ 25 mJy derived from these maps.  Machine-readable
    versions of the catalog with either B1950 or J2000 positions, and a
    printed catalog with B1950 positions only, are available.  The 4.85
    GHz weighted source counts S^(5/2)n(S) between 30 mJy and 10 Jy were
    obtained and agree well with previous results.
