Genus Anoplotherium, Cuv. — "With the same dental for- 

 mula as in Palceotlwrium, the present genus, like Dicliodon (fig. 

 130) has no interval in the series of teeth; neither the canine 

 nor any other tooth rising above the general level. The grind- 

 ing surface of the molar teeth somewhat 

 resembles and prefigures the ruminant 

 type; in the upper jaw the crown (fig. 

 128) is divided into a front (/, c) and a g- 

 back (f, d) part by a valley (e) extending 

 two thirds across. A second valley (cji) 

 crosses its termination at right angles, 

 forming a curved depression in each Upper J^Anophthe- 



division, which it thus Subdivides into ™*m commune (Eocene 



two lobes, concave towards the outer 

 side of the tooth. There is a large tubercle (m) at the wide 

 entry of the valley (e). The Anoplothere (fig. 129) was of a 

 lighter and more elegant form than the Pala?othere : its limbs 

 terminated each in two digits, with the metapodial bones 

 distinct, and the last phalanx hoofed. Some transitory cha-
