Hippopotamus palseindicus, Falconer and Cautley \ 

 Syn. Tetraprotodon palceindicus, Falconer 2 . 



This species is fully equal in size to the existing H. amphibius. 

 The number of upper incisors is unknown ; but there are three in 

 the mandible, the middle one being very small, and perhaps disap- 

 pearing in the adult ; the other two are large, and equal in size. 

 The mandibular symphysis is extremely short.
