The lower jaw is char- acterised by the great width across the condyles and then, anteriorly, by the in- wardly curved sweep to the long and narrow symphysis; there do not appear to be any incisors, and there are no indications of molars whatsoever; the splenial is very intimately fused to the dentary; the coronoid is small, and the surangular strong; the angular is large, but extremely thin. The fore-limb is repre- sented by a good right humerus, which may be of the same animal as the right ulna, radius, and manus. The humerus is of a type distinct from that known in any other Therap- sid; there is a very large entepicondylar, but no ectepicondylar foramen; the delto-pectoral crest is very long; distally, it merges into the shaft; it curves inwards and does not lie along the anterior border as in the Gorgonopsians, Fig. 34.—Whaitsia major.
