Family 



There seems no possibility of drawing any distinction of more 

 than generic value between Dicotyles, ffyotherium and its allies, and 

 Sus, and they all are accordingly included in this family. The molars 

 are bunodont, the upper ones having four main columns, which may 

 be simple (Hyotherium), or of extreme complexity (Hippoliyus) ; a 

 secondary column corresponds to the fifth column of the Anihra- 

 coiheriidce and Chceropotamidce. 



Genus DICOTYLES, Cuvier 1 . 



Dentition : 1. 1, C. p Pm. |, M. |. The upper premolars have 

 the same structure as the true molars.
