Genus HOMALODONTOTHERIUM, Huxley 1 . 



Dentition : — I. |, C. \, Pm. |, M. |. There is no diastema, and 

 the dentition is of a generalized rhinocerotic character ; the struc- 

 ture of the cheek-teeth being so like that obtaining in Cadurco- 

 therium (although of a rather more complex type), that there can 

 be little hesitation in placing the two genera in the same family, 

 although the present genus is sometimes classed with Nesodon. No 

 other portion of the skeleton is known.
