Size larger than in Tragtdics ; main metacai-pals and 

 metatarsals separate, or the latter alone uniting partially or 

 wholly into a cannon-bone in old age ; feet shorter and

Typified by Z>. navi (Kaup, op. cit. 1836; from the Upper 

 Tertiary of Eppelsheim, Hesse-Darmstadt, which differs from 

 the existing species by the presence (at any I'ate in many 

 cases) of the first lower premolar. 



At the present day the genus is restricted to the equa- 

 torial forest-zone of Africa.
