Thus Pd4 of Hominidae is less elongated, its cusps are blunter, the paracone and protocone are more widely separated, the cingulum is absent (except sometimes the Carabelli cingulum), and the fovea anterior is frequently united with the trigon basin. The same may be said of the premolars. Pd3 is more highly molarised in that the metacone is nearly always distinct; in Homo the hypocone, however, is more rudimentary than in Oreopithecus. The canines differ markedly in shape (Text-fig. 12). The hominid canine is peculiar among Primates in that the basal part of the crown is elevated and the cusp is blunt and comparatively low, so that the mesial and distal shoulders, which correspond to the parastyle and metastyle of the cheek teeth, are situated relatively high on the crown (Remane, 1927). Thus the canine has become modified in the.
