UNGULATA 



ORDER VII 



Anoplotherium commune Cuvier. Upper Eocene (Gypsum), Mont- 

 luartre, Paris. Skull aad lower jaw. 1/.5- (Alter Blalnville.) 



Anoplotherium Cuvier (Eitrythermm Gervais) (Figs. 243-245, 247, A). Ecto- 

 loph of superior molars W-shaped, the anterior inner cusp conical, the posterior 



V-shaped, the intermediate 

 cone small. Canines pre- 

 molariform. Inferior molars 

 with two V-shaped crescents 

 and three internal cones, the 

 posterior of which shuts off 

 the posterior crescent. The 

 Anoplotheres were short- 

 limbed, thick-set ungulates, 

 provided with an unusually 

 long and powerful tail. They 

 were about the size of the 

 tapir, probably lived on 

 swampy lowlands, and used 

 the tail as a swimming organ. 

 Their three digits were per- 

 haps connected by a mem- 

 branous web. Abundant in 

 the Upper Eocene ; Europe.

 Diphhnne Kiitimeyer 



(Hyracodontherium Filhol) 

 (Figs. 246, 247, 4 C). Very 

 similar to Anoplotherium, 

 but smaller and more deli- 

 cate. The inferior molars 

 are characterised by the fact 

 that the two antero-internal 

 cusps (a, ^■') are placed close 

 to each other and form a 

 pj^_ 245. bilobed pillar. The first
