of Horse from Central Asta. 23 
more remote parts of Asia called wild by Col. Prejevalsky. 
“Wild horses, called by the Mongols dzerlik-adu, are rare in 
Western T'saidam, but more numerous near Lob-nor. They 
are generally in large herds, very shy, and when frightened 
continue their flight for days, not returning to the same place 
for a year or two. Their colour is uniformly bay, with black 
tails and long manes hanging down to the ground. They are 
never hunted, owing to the difficulties of the chase”’ (Preje- 
valsky’s ‘ Mongolia,’ English ed. vol. 11. p. 170). 
Our specimen of Hquus Przewalskii is about three years of 
age; in size it is no bigger than the kulan and djiggetai; its 
head is nearly of the same length as that of those animals, 
but lower, and better shaped near the end of the muzzle and 
nasal bones, with shorter ears than those of the wild ass. Its 
size 1s decidedly small in proportion to its head. In shape it 
takes after the horse; its legs are relatively thick for the size 
of its body, its hoofs rounder and broader, and its tail better 
furnished with hair, than in the case of the wild ass. Its 
colour is dun, with a yellowish tinge on the back, becoming 
lighter towards the flanks, and almost white under the belly. 
Its hair is long and wavy, brick-red on the head and nasal bones, 
of the same colour but longer on the cheeks and about the lower 
jaw. ‘The extremity of the nose is covered with almost white 
hairs, a remarkable contrast to the brick-red on the upper part 
of the head. A short upright | hogged] mane extends from 
between the ears to the withers, of a dark brown colour, with 
long yellowish hairs on the margins. It has no stripe of the 
same colour as the mane along the back, as all Asiatic asses 
and dun horses have, and a hardly perceptible one along the 
pelvis. The upper half of the tail is of the same colour as 
the back; it is longer, thicker at the root, and more bushy 
than that of any kind of ass; halfway down the tail yellowish 
hairs are mixed with the brown; and the extremity is dark 
brown or nearly black. ‘The fore legs are brown near the 
hoofs and on the knees; and oblique indistinct bars of brown 
hair extend down the legs. The prevailing colour of the 
lower parts of the fore legs is brown, a peculiarity never 
known to occur with wild asses, these having only a narrow 
barely distinguishable brown margin round the upper rim of 
the hoof. Dark hairs also occur on the hind legs about the 
hoofs and much higher. 
Thus in external appearance as well as in colour Hquus 
Przewalskii is distinct from all wild asses indigenous in the 
same and neighbouring tracts. Moorcroft’s Asinus kiang 
from ‘Tibet differs from it in colour. Of two specimens 
brought by Prejevalsky from Northern Tibet, the colour of one
