%X A recent investigation of radio sources in the northern hemisphere was made by Kellermann (1966). He attempted to explain some of the characteristics of the sources that were observed to have c~ed spectra. In order to make a similar investigation possible for sources in the southern hemisphere, more observations especially at low frequencies are needed. Recently surveys have been published at 153 MHz (Hamilton and Haynes 1967) and between 40 and 120 MHz (Haynes and Hamilton 1968). Contuluing these observations, we report here on measurements of 11 radio sources made at the Australian National Radio Astronomy Observatory, Parkes, N.S.W., in January 1968.
