Characters. — Nearly allied to the next species, but the horn-cores rising 

 from a more prominent frontal ridge, sloping more away from the plane of 

 the forehead, and their proper front surface directed more towards the 

 frontal aspect, being thus more like the tamarau. In the typical form the 

 horn-cores are markedly triangular, but in the specimens described under 

 the name oi" occipitalis the front outer angle is rounded off, so as to give 

 a pyriform section, and the tips are curved forwards. By the late Professor 

 Riitimeyer these two variations were not considered worthy of specific 

 separation, the second being distinguished as the troclioceros form. 



Distribution. — Northern India during the Pliocene period.
