1908.] SEROWS AND GORALS. 185 



100 mm. (=4 inches). Conceivably the smallness of the hoi-ns is 

 a racial chai^acter ; but I am more inclined to attribute it to 

 immaturity. 



The typo of C. s. jamt^achi is the mounted specimen above 

 referred to in the Mammal Gallery of the British Museum 

 (Reg. No. 2.10.12.1). 



Of all the extra- Himalayan Serows recorded up to the present 

 time, this subspecies is most nearly allied to C. s. milne- 

 eclwardsii David *, from Eastern Tibet. The colour of the body 

 in the latter, however, is not so black as in C. s. jamrachi, and 

 the tint of the legs is much more ferruginous. The darkening of 

 the legs is carried still fiu^ther in C. s. argyrochcetes Heude t, 

 from Sze-chuen and Tche-kiang, for the anterior side of the 

 cannon-bone is blackish. The mane, moreover, is grey. In the 

 coloration of the legs C. s. argyrochcEtes lies midway between 

 C. s. jamrachi and the typical C. s. sumatraensis, while in the 

 greyness of the mane it resembles the latter race. Of C s. 

 argyrochcetes the British Museum possesses two specimens, one a 

 flat skin from Sze-chuen, obtained from Berezowski in 1896, 

 the other a mounted specimen said to have come from Tibet, 

 which Mr. Lydekker has recently described and figured (P. Z. S. 

 1905, p. 329, pi. viii.). 



Subsp. ROBixsoxi Pocock. 



Abstr. P. Z. S. No. 55, p. 12, March 17, 1908. 



Prevailing colour black, the hairs white at the I'oot, usually 

 brownish mesially and jet-black in their distal two-thirds. Head 

 black, with a narrow grey rim to the upper lip and corner of the 

 mouth, this grey continuous with a large patch of the same 

 colour tinged in places Avith brown, which extends backwards 

 to a point on a level with the orifice of the facial gland ; chin 

 black. Mane formed of a nearly equal mixture of white and 

 black hairs, without any red ; its anterior end, forming the 

 occipital tuft, black with small white tips. The mane does not 

 form a white mat-like patch on the withers. It is continued 

 down the spine as a black crest. On the throat there is a small 

 patch formed by the rufous or white tips to the hairs. On the 

 tail and the outer side of the thighs there is a noticeable quantity 

 of reddish-brown hair, and hairs of a similar hue surround the 

 anus and extend along the edge of the under side of the tail, 

 the upper side of which is black. Lower surface a dirty dark 

 brown ; inner side of thighs at base scantily clothed with dirty 

 white hair. Fore and hind legs black, with dark chocolate-brown 

 knees, hocks, and fetlocks. 



Measurements in English inches of freshly stripped skin : — 



Total length from nose- tip to tail-tip 60, tail 7 (with hair 10). 

 Height at withers 36, hock to heel 13^, knee to heel lOg, distance
