whicli provokes comparison with the lower jaws of 

 many anthropoids, especially those of the gorilla 

 and chimpanzee (Fig. 37). The resemblance consists 

 chiefly in the uprightness of the anterior surface, 

 and especially of the body of the maxillary bone.

In anthropoids this surface of the bone retreats from 

 the row of teeth backwards and downwards to the 

 lower edge of the body of the maxillary bone (Fig.

 the lower jaws of some modern Papuan skulls (of

New Hebrides and elsewhere), there is a certain 

 approximation to the simian type. A fossil ape 

 (Dryopithecus Fontanii) has been found in the Middle
