Three fossil Felinae are described. These are a leopard differing only slightly from the living species, and named Panthera pardus incurva; and two species of lion-like animal, which are not identical with the living species. The specimens of the latter two species are very fragmentary, and they have not been named, but are merely referred to as the Swartkrans and the Kromdraai “lions”. It is suggested that the latter may possibly be identical with Panthera shawi (Broom).
It is concluded that the differences in the feline faunas of the deposits at Sterkfontein, Swartkrans and Kromdraai indicate some difference in the ages of the deposits.
