New redshifts are presented for 10 rich clusters of galaxies of the Abell et al. (1989) cluster catalog (Abell's southern extension). These are the first results of a survey of southern cluster redshifts, to be completed out to z of about 0.1. In six clusters the redshifts of the first and second brightest galaxy were measured, giving typical differences of about 650 km/sec. This gives confidence in both the identification of the brightest galaxies and the redshift measurement. It is also found that the redshifts agree well with the log (cz)-m10 relationship.
