Catarhina

Group SIMIADE (q.v.), including the Old World monkeys or apes proper. They may or may not have tails; cheek pouches and natal callosities are often present. The thumb as well as the great toe is opposable to the other digits. The nostrils are close together and look downward. The dental formula is the same as that of man. The canines are quite large in the males. The suture between the præmaxillæ and maxillary bones remains distinct. There is little or no chin, and the superciliary ridges are very prominent. There are two groups, the dog-like apes, CYNOMORPHA ( Cynopitheci ), and the man-like apes, ANTHROPOMORPH A. The first group is again subdivided into two families, the CYNOPITHECIDE and the SEMNOPITHECIDÆ (q.v.).
