The right ramus of the type is preserved. In addition to this we possess other lower jaws and fragments of the jaws of other individuals of the same species. The incisor alveolar border is more produced and rounded so that the incisors and canines form a more curved line from side to side between the first premolars than in P. Fig. 33. Lateral view of mandible of Promerycochxrus vantasselensis. No. 1230; 5 nat. size. The symphysis is quite strong, but the chin is not nearly as wide as in the latter species. The ramus of the type. No. 1230, unfortunately lacks the angle and coronoid process, but No. 1232 has the lower jaws nearly complete and shows no other important differences from P. carrikeri, except those stated above.
