. Bulletin of the British Museum (Natural History), Geology. 5o8 MEGISTOTHERIUM FROM thought it might be creodont and compared it to Apterodon. The astragalus is very different in size and proportions from that of Megistotherium, and I would agree with him that it could belong to a creodont of about the size of Apterodon. Savage (1965) described some material of Pterodon africanus from Kenya, and he referred three additional teeth to a new species, P. nyanzae. The teeth are very similar to those of Hyainailoiinis sulzeri, but slightly smaller and comparable with what would be expected of H. fourtaui. My present view is that they should be transferred to the genus Hyainailourus and the specific name retained until further evidence is available. Five specimens from the Bugti Beds of Pakistan arrest our attention. Forster Cooper (1924) described and figured a mandible (M12049) as Anthracotheruim ingens. The specimen is patently not an anthracothere but could belong to Megis- totherium, of a species rather larger than M. osteothlastes. The specimen has a large canine which recalls the Rusinga specimen mentioned above. The evidence of the alveoli suggests three incisors were present. The Ii alveolus is preserved on both sides and that of I2&3 on the left side only. The alveoli decrease in size toward the canine, and the third incisor has a small alveolus almost tucked under the canine. Immediately behind the canine is a deep alveolus suggesting the presence of a single.
