found in the same deposits as the earliest known remains of 

 Tetrabelodon angustidens, and, as in the case of that species 

 its ancestors probably lived in Africa, though up to the pre- 

 sent no traces of them have been discovered. In the later 

 Miocene beds occur a number of species, some of enormous size 

 (e. g. D. gigantissimum from Roumania). The genus finally 

 disappears in Lower Pliocene times. The chief peculiarity 

 of these animals is, that the front part of their lower jaw is 

 turned sharply downward and bears two large tusks (fig. 17 > 



This species has, of course, no near relationship with Dino- Wall 

 therium (fig. 17), which forms a side branch of the Probo- 

 scidea, and is widely different from all the other members of 

 the group. The earliest known member of the genus is 

 Dinotherium cuvieri, a comparatively small animal^which is
