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. 



Hob. S. Europe. 



27490. Two upper true molars and the third left lower true molar ;
