The above enumerated mammalia may be considered as well ascertained and 



:t species. I am still uncertain whether Eucrotaphus* is distinct from 



iochcerus ; and have, therefore, not included it in ihe list. The specimens 



upon which the former genus was characterised, apparently indicate two distinct 



species : whereas, all the teeth which have been found of the latter, so far have 



indicated but one species.
