There are no cingula on the teeth, and the enamel is perfectly smooth. 

 The appearance of the crowns as well as the bones indicates an adult 

 animal. 



The bones of this animal were found together on a bluff of Cotton- 

 wood Creek, Wyoming, by myself, while attached to Hayden's geologi- 

 cal survey of the Territories for 1872.
