 centre of the face is narrow and keeled on the sides ; while in 

 the skull of E. Onager from Kutch the forehead is flat between

 back edge of the teeth ; it is far back, being directly over the 

 front edge of the cheek-ridge and the back end of the third 

 grinder ; while in all the three specimens of the skulls of E. 

 Kiang this foramen is lower down, being nearly in the centre of 

 the space between the face-line and the base of the teeth, and it
