molar teeth of Palceotherium (fig. 99) approach nearer to those 

 of the rhinoceros ; but in the number, kind, and general ar- 

 rangement the entire dentition resembles that of Pliolophus. 

 The skull affords indications that the Palseothere possessed 

 a short proboscis. It had three toes on each foot, each termi- 

 nated by a hoof ; the middle one being the largest. The 

 femur had a third trochanter, 

 and the dorso-lumbar vertebrae 

 were 21 in number. Several 

 species of Palceotherium have 

 been determined, ranging from y M 

 the size of a sheep (P. curtum) 

 to that of a horse (P. magnum).
