Equus. 399 
The Indian species of this genus are properly asses ; there are two 
kinds, although it has been asserted by many-—and some of them good 
naturalists, such as Blyth—that the Azang of Thibet and the Ghor-khur- 
of Sind and Baluchistan are the same animal.

with square crowns marked by wavy folds of enamel. The incisors are: 
grooved, and are composed of folds of enamel and cement, aptly de-- 
scribed by Professor Boyd Dawkins and Mr. Oakley as being folded in 
from the top, after the manner of the finger of a glove the top of which 
has been pulled in. ‘The marks left by the attrition of the surface give- 
an approximate idea of the age of the animal. The stomach is simple— 
the intestinal canal very long and czecum enormous.

The following account I extract from Jerdon’s ‘Mammals of India,” 
p- 238, which epitomises much of what has been written on the 
subject :— 
“The ghor-khur is found sparingly in Cutch, Guzerat, Jeysulmeer 
and Bikaneer, not being found further south, it is said, than Deesa, 
or east of 75° east longitude. It also occurs in Sind, and more 
abundantly west of the Indus river, in Baluchistan, extending into 
Persia and Turkestan, as far north as north latitude 48°. It appears 
that the Bikaneer herd consists at most of about 150 individuals, which 
frequent an oasis a little elevated above the surrounding desert, and 
commanding an extensive view around. A writerin the /zdian Sporting 
Review, writing of this species as it occurs in the Pat, a desert country
