DESCRIPTION.—Hair in winter long and softish; facial and lateral markings wanting; breast, belly and anal disk which surrounds the tail dirty white; the rest of the body grizzled fawn-colour, becoming more rusty towards the anal disk, a rusty line sometimes running through the disk to the short tail, the tip of which is rusty brown; the hairs about the corners of the mouth elongated. In the summer the coat is short and of a slaty-grey colour. Ears very short; horns long, annulated—diverge as they rise, bending forwards and backwards, again forwards, and a little inwards at the tips. Skull: anteorbital fossa very shallow, nasals converging to a point, and rather elongated (Sir Victor Brooke, 'P. Z. S.,' 1873, p. 547).
SIZE.—Height, about 18 inches.
There is a lovely little photograph of this gazelle in Kinloch's 'Large Game of Thibet,' wonderfully life-like; the head seems to stand out from the page. He describes it under Hodgson's generic name, Procapra, but there is no reason for separating it from Gazella. He says: "The goa avoid rocky and steep ground, preferring the undulating plains and gently sloping valleys. Early in the season they are to be found in small herds, frequently close to the snow; as this melts they appear to disperse themselves over the higher ground, being often found singly or in twos and threes."
| Saiga Antelope. |
Between the gazelles and antelopes proper comes the chiru (Pantholops Hodgsonii), though strictly speaking it is, with the saiga antelope (Saiga Tartarica), though in a somewhat less degree, connected by cranial affinities with the sheep. The saiga is notable for its highly-arched nose and inflated nostrils, which are so much lengthened as to necessitate the animal's walking backwards when it feeds. The chiru is not quite so developed in this respect. The skull of the saiga is unique among ruminants, and those who wish to become acquainted with its most minute osteological details should refer to an article on this animal by Dr. James Murie in the 'P. Z. S.,' 1870, p. 457. I can only here give a very brief summary of the chief characteristics. Looked at in profile, the nasal bones we find to be remarkably short, the face being hollowed out, as it were, between the upper nasal cartilage and the very long and narrow maxillary and pre-maxillary bones; great vertical depth from the top of the nasal to the bottom of the maxillary bones; a very prominent bovine orbit, above and a little behind which the short tapering horns of a gazelle type are placed. The lower nasal cartilage is prolonged on to the fibrous cord of the nares, and the profile view of the animal in life is that of a grotesquely Roman-nosed antelope with swollen nostrils. Its nearest relative in India is the chiru, which has certain points of resemblance. The nose is but slightly arched, but the nostrils are more swollen than in antelopes as a rule. This is not sufficiently rendered in an otherwise admirable coloured plate in Blanford's 'Scientific Results of the Second Yarkand Mission,' but it is more apparent in the photograph of the head in Kinloch's 'Large Game of Thibet.' Another approach to the saiga is in the position of the horns, which, though of the same class, are much longer and more attenuated, but the position over the eye and the osseous development of the orbit are the same. The nasal bones are also shorter in proportion to other antelopes. The super-orbital foramina just under the horns, which are marked in most antelope and deer, are very minute in Pantholops. Dr. Murie notices the inflation of the post-maxilla in the saiga, and states that a similar extension is to be found in the chiru.
