Genus HOMALODONTOTHERIUM, Huxley 1 . 



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

 the dentition is of a generalized rhinocerotie 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. 



Homalodontotherium cunninghami, Flower 3 . 



This is the only known species. 

 Hob. South America. 



46295. The palate, showing all the dentition except the right m-2 

 (Fig.) and m-3 ; from Tertiary strata on the river Gallegas, south- 

 east Patagonia. This and the next specimens are the types 

 of the genus and species, and are described and figured by 

 Flower in the Phil. Trans, for 1874, p. 173, pi. xvi.
