 oasJ-meuuraa, and chiefly from the lias and oolitic formations, of 

 which they are a characteristic feature; these are (). caneala, O. Jicaiui,

 in particular must be excluded from the genus, and probably belong* 

 to Knropteru.

 small; the cutting-teeth are nearly equal-sized and shelving; and 

 there are no supplemental lobes to the grinders. The hoofs are trian- 

 gular, and being shallow behind, they have distinct interdigital fossie.
