The coalesced pleura-pophyses, pi, b, of the two anterior sacrals chiefly form the sacro-iliac joint. The neural arch of the last two sacral vertebrae, d,c, is incomplete. The first coccygeal vertebra, ib. c, e, is less flattened and is SKELETON OF BIMANA. 557 shorter than in the Chimpanzee : the neurapophyses, b, are longer,the diapophyses, c, are shorter: the terminal coalesced vertebrae,c, d, are reduced to their ( centrums.

The spines of the sixlower cervicals are shortand bifurcate. As a rule,the vertebrarterial canal iscompleted in the seventhas in the other cervicals. In the atlas there is a tubercle from the hypapophysis repre-senting the body, and a rough surface on the neural arch inplace of a spine. The vertebral artery perforates the transverseprocess lengthwise, and afterwards grooves the neural archbehind the produced angles of the anterior zygapophysis. Thebody is longer and deeper in proportion to its breadth than inthe Gorilla. The surface for the odont
