46. Bos gaurus readi. 
Bos gaurus readi, Lyddekker, Zoologist, ser 4, VII, p. 266 (1903) ; 
id, Game Animals of India, ete., p. 60-62, fig 5 (1907). 
A pair of detached horns, exact locality unknown. 
Though short (length along outer curve 23} inches) these 
horns are very massive for their length having a basal girth of 17 
inches. 
Mr. K. G. Gairdner (in Journ N. H. Soc. I. p. 118 and plate) 
gives measurments of some Siamese heads and figures two 
pairs which show what very different forms the horns of this 
species may take; Gyldenstolpe ( Kungl. Sv. Vet. Akad. Handl. 57, 
No 2, p. 57, pl. 1, fig 3) figures as B. gy. readi a very extraordinary 
trophy from Prachuap Kirikan, S. W. Siam, with the bases of the 
horns much swollen and rugose and nearly touching on the intercor- 
nual ridge: it is, however, in several ways more suggestive of a 
banteng than of a gaur. 
Practically all Siamese specimens have been obtained in the 
north or west. 
(I am indebted to Mr. W. E. Trotter for these horns and four 
pairs of the Cervus antlers mentioned below ) 
47. Capricornis sumatraensis annectens, subsp. ». 
Intermediate between C. s. swmatraensis and C. s. milne- 
edwards: of Szechuan. Differs from the first in having the lower 
parts of the limbs largely rufous, and from the latter in having the 
rufous colour not extending above the knees and hocks. 
General colour black but the bases of the hairs on back and 
sides of body largely white, giving a grizzled appearance to the 
pelage. Mane very variable in size and colour but white basally ; 
anteriorly the hairs nearly always largely black ; posteriorly the 
distal portion of the hairs variable, black or chocolate or pale drab: 
sometimes with a few entirely dark hairs intermixed. Tail with a 
few rufous or albescent hairs. 
Outer surface of ears with many rufous hairs basally, inner 
surfaces white. Extremity of muzzle and the lips white; a large
