%X A catalogue has been prepared of the radio sources observed between declinations _200 and _500 , using the Sydney cross-type radio telescope at a wavelength of 3·5 m ; a total of 892 sources is listed. This supplements an earlier catalogue in the declination zone + 10° to _20°. In addition to the positions and intensities of the sources, angular sizes of 50 of the strongest are given: several are found to have a size less than 15" arc. As before, identifications with bright optical objects have been sought, and a number of galaxies of apparently abnormal radio emission listed. Statistical analyses of the distribution of the radio sources give results very similar to those obtained using the earlier catalogue. \Vithin the uncertainty in the data, the distribution appears uniform in depth and there is a siguificantly greater number of sources of large apparent size than expected from chance blending effects.
