Hippopotamus minutus, Blainville "' . 

 Syn. Hippopotamus minor, Falconer 2 . 



As far as is known, this species is closely allied to the last. The 

 specimens noticed below are referred to it on the authority of Fal- 

 coner, but they indicate an animal considerably larger than that to 

 which the specimens figured by De Blainville belonged, being inter- 

 mediate between the latter and H. pentlandi ; and it appears in 

 reality that there is an almost complete gradation in size from the 

 largest fossil individuals of H. amphibius, through H. pentlandi, to 

 the smallest specimens of H. minutus.
