The genus Dinotherium, sole representative of the family 

 Dinotheriidae, differs in a number of important particulars from 

 the true Elephants. In the Elephants, if there is but a single 

 pair of incisors, these are found in the upper jaw ; in Dino-

theriiun there is apparently but a single pair, but these are 

 implanted in the lower jaw, the symphysis of which is much 

 prolonged and greatly bent downwards, so that the tusks emerge 

 at right angles to the long axis of the head, and are even bent 

 backwards. The molar teeth are five in number on each side of 

 each jaw and are hi- or tri-lophodont, not unHke those of the Tapir. 

 There is no cement in the valleys between the ridges of these 

 teeth, and there is a regular succession, the premolars being two 

 and the molars three.^ All the teeth are in use at the same time, 



^ There are, however, three milk forerunners of the iiremolars, of which one 

 has no successor.
