626 ON MIOCENE PROBOSCIDIA FllOM BALUCHISTAN. 



collection of the Briti.sli Museum without result *. It is certain 

 that it does not belong to any known form of Dinothermm, and 

 yet it is to teeth of that genus alone that it can be compared. 



Summary. 



The Proboscidi^ of the Bugti beds of Baluchistan consist of 

 a form of Bunolophodon angustidens and a small Dinotherium. 



The Indian B. angustidens is of a small type more primitive 

 than the French forms from Sansan, nearer to Schlesinger's form 

 subtapiroidea than his form typica, but not identical with it. 

 Lydekker's subspecific name var. palceindica may be retained for 

 the present until intermediate forms are found to occur. The 

 genus Hemimastodon is not supported by material in the 

 collection. 



The Dinotherium is not found to differ from the smaller 

 European forms nor from D. hohleyi of Africa, and it is doubtful 

 in the present state of knowledge whether the Indian Dinotheres 

 are separable from the European.
