In the Zoological Gardens, London, two specimens were received, one in 1842, and another about 1852, both of which lived there for several years. THE HIMALAYAN SNOW COCK, OR SNOW PHEASANT. The HIMALAYAN SNOW COCK, or SNOW PHEASANT (_Tetraogallus Himalayensis_), is grey upon the top of the head, cheeks, and nape. The feathers on the back are of a reddish grey, delicately spotted with black, and streaked with deep reddish brown. The chin, nape, throat, and lower breast are whitish. The upper breast is greyish white, decorated with crescent-shaped black spots. The rest of the feathers are grey, sprinkled with brown, and marked with two brown spots. The sides are paler than the mantle, and the lower covers almost white; the tarsi are dark grey. The eye is surrounded by two brown lines, which unite at the sides of the neck. The primary quills are white, their grey tips spotted with brown. The tail-feathers are of a reddish shade, spotted with black on the outer and grey on the inner web. The eye is deep brown, the bare patch behind it yellow, the beak pale horn-grey, and the foot yellowish red. The male is twenty-nine inches long, and forty broad; the wing measures thirteen, and the tail eight inches. The female does not exceed twenty-four inches in length. "These fine birds," we learn from Hutton, "are common in the Hazara Mountains, and are called by the Affghans _Kank-i-durra_, or the Partridge of the Ghâts. They are sometimes sold in the markets of Cabool and Candahar. They rise," he tells us, "in coveys of from ten to twenty, and usually have a sentry perched on some neighbouring rock, to give warning of danger by a low and musical whistle."
