OMNIVORA. 351 



The body in tins genus (fig. 644) was slender, the size being 

 about that of the existing Ass, and there was a long tail, 

 the vertebras of which carried chevron-bones below. The

feet are typically didactyle, no accessory toes being developed, 

 and the inetapodials being separate. The dentition is com- 

 plete, the teeth forming an uninterrupted and continuous 

 series, the crowns being nearly on the same level, and there 

 being no diastema between the canines and the prasmolars. 

 The dental formula is —

The molar teeth in some respects resemble those of the 

 Ehinoceros, and exhibit generalised selenodont characters. 

 The upper molars (fig. 643, c) have quadrate crowns, divided 

 into two principal lobes, an anterior and posterior, which 

 in turn are less conspicuously bisected by a fore-and-aft 

 depression. The wide valley separating the anterior from 

 the posterior lobe is distinguished by tlie presence of a large 

 accessory lobe or tubercle at its wide inner entrance. The 

 Miocene genus ChaUcotherium, which has been shown to 

 occur in ISTorth America, China, India, and Europe, is usually 

 placed close to Anoplothcrium ; but it seems questionable if 

 it should not rather be referred to the Pcrissodactyla, and 

 regarded as an ally of the Tapiridce or Brontotheridce. It 

 comprises species as large as the existing Rhinoceroses.
