The forehead of all the three specimens of the skull of E. He- 
mionus from Thibet is rather convex between the eyes, and the 
eentre of the face is narrow and keeled on the sides; while in 
the skull of HE. Onager from Kutch the forehead is flat between 
the eyes, and the centre line of the face is rather broader and 
rounded gradually off on the sides, and the incisive bone is longer 
and more gradually arched, making the incisor more perpendicu- 
lar in the latter than in any of the former. 
But the most distinctive character between the four skulls is 
in the position of the infraorbital foramen. In E. Onager it is 
high up, about one-third the space between the face-line and the 
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, beimg nearly in the centre of 
the space between the face-line and the base of the teeth, and it
