seems to be but little difference in this respect between the snmmer and winter 

 coats. The mane is shorter than in the kiang. Dr. Matschie describes the general 

 colour of the upper-parts as yellowish red with a tinge of grey ; the lower part of 

 the neck being of the same colour as the body, but ])a]er, while the iinder-]i irts, etc., 

 are greyish white, which is not sharply defined from the fawn of the upper-parts. 

 The brown dorsal stripe extends down the tail to the terminal tuft. In winter the 

 colour of the coat tends, I believe, to greyish. 



A male specimen from north-eastern Mongolia was living in the park at 

 Woburn Abbey in 1903 and 1004, and is figured in the Proceedimjs of the 

 Zoological Society for 1904. 



Judging from its coloration, the chigetai should be an inhabitant of more 

 desert country than that frequented by the kiang ; and by comparing accounts of 

 Mongolia and the Gobi with what I know of Ladak, this would seem to be the case. 



The exact locality where this particular specimen was obtained (by the 

 members of an expedition sent out by Mr. Carl Hagenbeck, of Hamburg), is the 

 neighbourhood of Lake Balkash in Central Kobdo, north-western Mongolia, a 

 spot lying east-north-east of Tarbogatai, the well-known hunting locality. 



The skull of a female (?) wild ass in the British Museum (No. 94. 2. }<. 3), 

 killed by Mr. St. George Littledale near Lake Koko-Nor, on the north-eastern 

 frontier of Tibet, adjacent to Mongolia, differs from that of the kiang by the 

 absence of the frontal pit, and may therefore belong to the chigetai. The form 

 of the fronto-nasal suture is not shown.

Size considerably less than in E. hemionus, the minimum recorded height being 

 3 ft. 8 in. and the maximum 3 ft. 10 in. Ears apparently much the same as in 

 the latter. Hoofs narrow and ass-like ; the front pair but little wider than the hind 

 pair. Profile of face nearly straight or markedly sinuous. Tail-tuft moderate. Dark 

 dorsal stripe very broad, iu some cases stopping sliort of the tail-tuft, and bordered, 

 at least jiosteriorly, by a band of white or whitish, which joins the white on the 

 buttocks and the back of the thighs. Colour of upper-parts, in the summer coat, 

 usually some shade of pale reddish fawn or sandy (isabelline) ; the light areas, which 

 vary from pure white to whity-brown, much the same as in E. hemionus, but 

 extending more on to the buttocks, and thence along the sides of the dorsal stripe, 

 and in some cases occupying more of the body and head. In winter, the long and 

 rough coat more or less decidedly grey ; in one instance distinctly mouse-grey with 

 sharply defined white areas. 



The cry of the Indian ghor-khar is described as being a '' shrieking bray," and 

 therefore perhaps not unlike that of the kiang ; but in the case of the Syrian 

 onager, and probably also iu that of the true onager, it is stated by the late Mr. E. 

 Blyth to be more like that of the common ass,* to the wild forms of which
