The projecting back edge of the lunate is narrowly pointed in Hippotragus in medial view, but not in the other genera or Pelorovis. 85. The unciform facet at the top of the metacarpal is angled in Hippotragus but not in Pelorovis, Oryx or Bovini (Text-fig. 36). Among the limb bone characters of Pelorovis were three which might be valid as specific or generic characters, but which were not seen in Bovini or Hippotragini. These were the small sustentaculum on the calcaneum, the antero-posteriorly long infraspinatus insertion on the humerus (PL 4), and the flexor carpi ulnaris origin on the medial side of the olecranon which extended almost to the top of the bone (Text-fig. 31). 86. Bovini have wider cervical vertebrae than Hippotragini. This may be owing to allometry at least in part, but the long cervical vertebrae of a large form. Please note that these images a
