We recently reported identifications for 71 extragalactic radio sources between declinations 0� and ?20� (Bolton and Ekers 1966). The identifications were based on a search of the 48 in. Sky Survey prints in positions etermined by Shimmins, Clarke, and Ek

Several catalogues of radio sources at 408 MHz have been prepared from observations made with the Molonglo cross telescope. These include (in chronological order) ‘The Molonglo Radio Source Catalogue 1’, the MC1, by Davies et al. (1973), the MC2 and MC3 by Sutton et al. (1974), MC4 by Clarke et al. (1976), ‘The Molonglo Deep Sky Survey of Radio Sources’ by Robertson (1977a,b,d) and ‘The Molonglo Reference Catalogue of Radio Sources’ (MRC) by Large et al. (1981). The catalogues MC1-4 cover selected areas of sky to a flux density limit of ~0.2 Jy to 0.3 Jy. The MRC includes extragalactic radio sources between δ = +18° and δ = −85° and is essentially complete at S408 = 1.00 Jy with raany sources to ˜0.7 Jy. The Wyllie (1969a,b) scale of flux density is used throughout.

Identifications with extragalactic objects are suggested for 55 radio sources with declinations between _200 and _44�. The identifications are based on a search of the Palomar Sky Survey plates in the position of sources in the Parkes catalogue. Eight of the identifications are with suspected quasi-stellar objects and the remainder with galaxies. Finding charts are provided for the fainter obje~ts.

A catalogue of 618 extragalactic radio sources obtained from a sky survey at 2700 MHz is presented. The area of 0�42 sr covers four southern zones of R.A. 03h to 04h , II h to 12h , 19h to 20h , and 23h to 00h, between Dec. -330 and -75�, with a region omitted in the llh zone which is close to the galactic plane. The catalogue is complete to a limiting flux density of 0�32 f.u. at 2700 MHz and is thought to be 90% complete at a flux density of 0�20 f.u. The positions are accurate to 15" arc or slightly better in both coordinates for sources stronger than 0�32 f.u.; the flux densities of the weaker sources are accurate to 0�02 f.u., and for sources stronger than 1 f.u. the accuracy is 3%.

Identifications or suggested identifications are given for 138 extragalactic radio sources in the declination zone 0� to +20�. The identifications are based on a search of the Palomar Sky Survey plates in the positions of sources in the Parkes catalogue. Forty-two of the identifications are with quasi. stellar objects or suggested quasi-stellar objects and the remainder with galaxies. The radio luminosity distribution and a possible variation in the identification percentage with galactic latitude are discussed.
