The Chiru, _Pantholops_, is allied to the Saiga. The horns of the male are long and nearly straight; they are ringed in front. The muzzle is swollen in the male; the nostrils are large, and provided with extensive sacs internally. The colour of this animal, which is exclusively Thibetan in range, is a pale fawn. The hair, in accord with its habitat, is very woolly. No living specimens have ever been brought to Europe. This creature has accumulated much {312} legend. Its blood is believed by the Mongols to possess virtues, and by means of the rings on the horns fortunes are told. Naturally the animal is on these grounds hard to stalk and shoot. [Illustration] FIG. 161.--Loder's Gazelle. _Gazella loderi._ x 1/10. The Gazelles, genus _Gazella_, are fairly numerous in species, which are both Palaearctic and Ethiopian. There are altogether twenty-five of them. The genus as a whole is characterised by the small or moderate size, the sandy coloration with white belly, the presence of dark and light stripes on the face and on the flanks. These streaks, however, are not always present, and their presence or absence serves to differentiate some of the species. The horns are usually present in both sexes. The horns are of fair length, ringed, and of lyrate form. The Springbok is separated from the rest of the Gazelles, to which genus it is clearly most nearly related, as a genus _Antidorcas_. This genus differs from _Gazella_ by having only two lower premolars as in _Saiga_. Otherwise it resembles the Gazelles; there is but a single species, _A. euchore_, which is African. {313} _Ammodorcas_ is closely allied to the Gazelles, but differs from them in having an elongated neck and also a long tail. _A. clarkei_, the only species, is limited to Somaliland. _Lithocranius_, not unlike the last, has a still longer neck, which makes it almost Giraffe-like; its tail, however, is short. The scientific name is derived from the "solid stony character of the cranium." In running, this Gazelle carries the head forward in a straight line with the body. It is African. _Dorcotragus_ with one species, _D. megalotis_, is a pigmy Gazelle restricted to Somaliland. Its likeness, on account of size and in some other superficial features, to the Klipspringer, led to its original confusion with that genus (_Oreotragus_). [Illustration] FIG. 162.--Sable Antelope. _Hippotragus niger._ x 1/20. The horns of the specimen figured have not nearly reached their full dimensions. A sub-family Hippotraginae, or Hippotragine section, includes a number of Antelopes which agree in the possession of four mammae, and of molars more like those of the true Oxen, of {314} horns of some length, present in both sexes, and of a longish tail. They are all African in range.
