The Snow-Partridge, which bears a general resemblance to the Ptarmigan in summer plumage, differs from all the Indian Gallinaceous birds in having the tarsus feathered half way down to the toes ; the eyelid is also completely covered with plumelets, a feature of unique occurrence among Indian game birds.
In the Snow-Partridge the sexes are similar in plumage and in size. The tail is composed of 14 feathers. The male is furnished with one strong but blunt spur. The wing is very pointed, and the first quill reaches almost to the tip of the wing.
