VERNACULAR NAMES:--_Ragoa_ and _Goa_ (_Hodgson_); _Ata-dzeren_ (_Przewalski_); all of the Tibetans. Height at withers about 25 inches. Fur close and thick. General body-colour pale fawn, darkening posteriorly and becoming almost rufous brown along the edges of the white anal patch. No lateral nor pygal bands. Face without any trace of the ordinary Gazelline markings, coloured like the body, or the top of the muzzle sometimes brown; hairs on the sides of the muzzle elongated, so as to form a sort of lateral tuft, which extends backwards under the eyes. Ears short, narrow, pointed, well haired, coloured like the body. Rump with a prominent white patch surrounding the base of the tail. Tail quite short, projecting little beyond the fur, its end black or dark fawn. Limbs white or very pale fawn; no knee-tufts. “In the summer the coat is short and of a slaty grey colour” (_Brooke_). Skull rather broad in proportion to its length. Anteorbital fossæ practically obsolete. Nasals broad behind, evenly tapering forwards. Basal length 6·4 inches, greatest breadth 3·75, muzzle to orbit 4·0. Horns slender, of median length, much compressed laterally, very closely ringed. With the exception of their tips (2–3 inches), after starting vertically, they curve evenly and strongly backwards, diverging laterally but little. Tips gently curved upwards and slightly inwards, reapproaching each other above to a certain extent.
