ANTILOPINiE 37 



lachrymal depressions ; basal length about 9^ inches. Fine 

 horns measure from 13 to 15f inches in length, with a basal 

 girth of from 3^ to 5, and a tip-to-tip interval of from 

 4^ to 7i inches. 



In the rutting seasons the males develop a goitre-like 

 swelling in the throat. The range formerly extended from 

 the Little Altai, in north-western Mongolia, through the 

 southern part of Transbaikalia and northern and eastern 

 Mongolia to Amurland and Kan-su ; it now stops consider- 

 ably short of the Anmr peninsula. This species is so largely 

 intermediate in characters between G. picticcmdata and 

 G. 2)Tzeivalskii on the one hand and G. subgutturosa on the 

 other as to render it inadvisable to give Procapra more than 

 subgeneric rank. 



So far as the specimens in the collection are concerned, 

 the coloured figures in the Book of Antelopes are misleading, 

 the hind-quarters, flanks, and limbs being represented as 

 white, and the fawn area merely as a kind of saddle. Brooke's 

 description is approximately true to nature. 



If the Altai form be distinct, the following two races 

 may be recognised : — 



A. F'a.wn area smaller ; horns less spreading ; skull 



narrower G. g. gutturosa. 



B. Fawn area larger ; horns more spreading ; skull 



broader O. g. altaica. 



A.— Gazella g"utturosa g-utturosa. 



General characters those of the species. 



Typical locality eastern Mongolia. 



67. 1. 8. 3-4. Two frontlets, with horns. Mongolia. 

 The skull and horns, purporting to be one of these specimens, 

 figured by Gray in the Free. Zool. Soc. 1867, p. 215, pertains, 

 as pointed out by Pousargues {op. cit.), to a gazelle with 

 large lachrymal depressions, and therefore with equally 

 large face-glands. Gray's figure is reproduced in the Book of 

 Antelopes, vol. iii, p. 87. Presented hi/ Dr. Lockhart, 1867. 



70. 2. 10. 37. Skull, with horns, and skin in winter coat. 

 Nortli of Pekin ; collected by E. Swinhoe, Esq. Length of 

 horns 9|, girth 4, tip-to-tip interval 4| inches. 



Purchased, 1870.
