“Towards the end of summer the dzerens are very fat, and are eagerly hunted by the Mongols for the sake of their delicate flesh, and also for their skins, which are made into winter clothing. The nomads, however, rarely wear the skins themselves, but sell them to Russian merchants at Urga and Kiakhta. Dzerens are also snared in traps made in the shape of a shoe of tough grass. When caught by the leg in one of these the animal lames itself in its struggles to get free, and becomes unable to move.” Besides the Russian explorers already mentioned, the only traveller, so far as we are aware, that has met with Przewalski’s Gazelle in its native wilds is the well-known explorer Mr. St. George Littledale, F.R.G.S., who brought home a skin and skull of this species from his adventurous journey across Central Asia in 1893, and presented them to the British Museum. In the narrative of Mr. Littledale’s expedition, which is contained in the third volume of the ‘Geographical Journal’ (p. 465), will be found an allusion to this Antelope as observed by him near the Lake Koko Nor. The north shore of this lake, first seen by Mr. Littledale on the 3rd of August, 1893, was flat and swampy, and there were many of these antelopes feeding on it in company with Wild Asses (_Equus kiang_). In some MS. notes with which Mr. Littledale has kindly favoured us on this subject it is stated that he first saw examples of this Gazelle south of the Nan-Shan mountains in about lat. 38° 30´ N. and long. 96° 30´ E. On that occasion, he says, they were high up above the party, and nearly all males, but, as Mr. Littledale was then expecting an attack from the Tanguts, he did not like to leave the caravan to try after them. As the valley of the Buhain-Gol (the river which flows into Lake Koko Nor) was descended, the old males became scarcer, and round the lake, where he procured the specimen now in the British Museum, there were large bands of females accompanied by young males. Besides Mr. Littledale’s specimens already mentioned, the British Museum contains a beautiful pair of this Antelope obtained in exchange from the Museum at St. Petersburg, from which our figures representing both sexes (Plate LIII.) have been prepared by Mr. Smit. It will be observed at once that though in its general form and coloration this species is somewhat similar to _G. picticaudata_, the shape of its horns is quite different, and readily distinguishes this species from its allies.
