This animal agrees better than the Zebus with the figure of the 
Humped Cattle on the ancient Egyptian tombs.—Long’s Egypt, 
p- 57. f. 169. 
Mr. Whitfield brought a pair of these animals. The male 
(now in the Zoological Gardens, 1850) is white, with a few brown 
specks on the head; the female yellow-brown, the head even 
narrower than that of the male. Purchas describes them as 
yellow.

This animal was imported as a Yak; it was for some time at 
the Gardens of the Zoological Society, but has been lately trans- 
ferred to Knowsley. 
The travellers in Tibet state that half-bred Yak are common 
as domestic cattle. -
