Family SULD.E. 



There seems no possibility of drawing any distinction of more 

 than generic value between Dicotyles, Hyotherium 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 (Hippohyus) ; a 

 secondary column corresponds to the fifth column of the Anthra- 

 cotheriidce and Choeropotamidce. 



Genus DICOTYLES, Cuvier 1 . 



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

 the same structure as the true molars.
