Palse other ium javali (Filhol 1 ). 

 Syn. Paloplotherium javali t Filliol 2 . 



This species is of slightly smaller size than P. crassum ; its di- 

 stinctive characters being the elongated crowns and tall cusps of the 

 upper true molars, the presence of a large quantity of cement in the 

 hollows of all the cheek-teeth, the approximation of the upper canine 

 to the premolars and its apparent separation from the incisors. In 

 these respects the species approaches Anchitherium.
