is placed in a line over the back edge of the second grinder, some 
distance in front of the end of the cheek-ridge. The under sur- 
face of the body of the posterior sphenoid is narrow and convex 
in EH. Hemionus and broad and flat in H. Kiang. The vomer is 
much more compressed in the latter than in HE. Hemionus. I am 
not certain that the distinctions here described may be sufficient 
to show that these two animals are separate species, but they m- 
dicate the necessity of the subject being more fully examined. 
In the position of the suborbital foramen the H. Hemionus 
more nearly resembles the E. Asinus, and the E. Onager that of 
E. Zebra and HE. Burchellit.— Gray, Proc. Zool. Soc. 1849, 29. 
Two of the skulls of the Equus Kiang show the small rudi- 
mentary grinder in front of the other, but this tooth is to be more 
or less distinctly observed in the skulls of the other Equide in 
the Museum Collection. I may observe, that in the skull of 
Equus Burchell in the British Museum Collection, this tooth is 
placed on the inner side of the first true grinder. 
The suborbital foramen in the skulls in the India House 
from Thibet rather varies in position, but in all it is placed over 
the middle or third tooth. In the old male it appears to be 
rather higher than im the nearly adult female and im the young 
skull, where the hinder grinder is just springing out. 
This animal must not be confounded with the domestic asses 
which are used for burden in Thibet.— Capt. Strachey. 
The male Kiangs are larger and deeper coloured. They live 
in troops of from eight to ten under the care of a solitary male, 
where the thermometer is below zero. They live partly on the 
plains and partly on the mountains, and the lower surface of the 
hoof varies considerably in form and concavity, perhaps from that 
circumstance. 
The Ghoor Khur of Ludakh, according to Moorcroft, is white 
about the nose and under the neck, the belly and legs; the back 
is light bay and the mane dun. They herd in droves, fly at a 
trot, stop, and look back.—H. Smith, Equide, 310. 
Moorcroft saw the Kiangs on the highest summits of Thibet, 
in their shining summer coats and with their antelope form, 
scouring along in numbers.—H. Smith, Equide, 286. 
Dr. Walker observes—The Kiang neighs like a horse. The 
Wild Ass of Cutch brays like an ass. The Kiang has no zebra 
stripes, neither in the adult nor in the foal. The Wild Ass of 
Cutch: transverse zebra stripes are seen on the shoulder in the 
adult, and still more in the foal. Sometimes also the shoulder 
cross has been seen. The habitat of the Kiang is on the hgh 
table-land of Thibet; of the Wild Ass of Cutch in the sultry 
plains near the mouth of the Indus. 
The Kiang of Chinese Tartary greatly exceeds that of the
