Also probably from 3aN is L40759 (Fig. 2), the greater part of a left horn-core with a rather damaged base and an index of 42,2 x 46,3. Horizon Tragelaphus is much better represented in bed 3aS than in either 3aN or the QSM. Nearly all the horn-cores were picked up by mine workers, many in 1966-7, and were not recovered from controlled excavations. Description On horn-core L6574 the posterolateral keel is weaker than the anterior one and can hardly be seen at all. This may have been an unusual individual in life or the fossil may have suifered water rolling after death. In the other horn- cores the posterolateral keel is always strong. The anterior keel is rarely as strong as the posterolateral one, but it can be seen to be so at the very bases of L5252, L5868 and L6568. A part of a left horn-core, L33779, is about 140 mm long and has a strong groove alongside, or instead of, a keel. In comparison with the living, similarly sized species Tragelaphus angasi and T. spekei, the horn-cores are less compressed anteroposterior^, inserted more uprightly, and look as if they were inserted less far behind the orbits. The insertions must.
