M. 2690. Part of the right ramus of an old individual of a small- 

 sized species of Equus, showing the last four cheek-teeth ; 

 from the Narbada Valley. It is not improbable that this 

 specimen is specifically distinct from E. namadicus.

As the writer has been unable to specifically distinguish the 

 specimens referred to the foregoing forms from E. caballus, they are 

 all provisionally referred to that species ; but it is quite probable 

 that they may really belong to more than one species, as it has been 

 shown by Leidy, Riitimeyer, and others that it is impossible to di- 

 stinguish the teeth and bones of many of the existing Equidce from 

 one another. In a memoir on the Pleistocene horses of Europe, 

 Nehring 7 refers the great majority of the specimens examined by 

 him to E. caballus, but says that there is also good evidence of the 

 existence of E. hemionus. In the Pleistocene race of the present
