As regards its distribution in the present epoch, Dr. Radde points out that, like the Dziggetai (_Equus hemionus_) and the Argali Sheep (_Ovis ammon_), the Mongolian Gazelle has retreated to the south and east from the Russian frontiers since the days of Pallas. There are at present only two places on the southern borderlands of Transbaikalia in which this Antelope remains during the summer and breeds every year. One of these is a district east of the Dsŭn-tarei which is seldom entered even by the shepherds of the Cossacks. It is an uninhabited and rather mountainous country, without wood or bushes, varied by salt-and some freshwater lakes, and covered only with yellow _Elymus_-grasses. The other district, which is of a similar character, lies north of the left bank of the Argunj, where this river enters into the Russian territories between the border-posts of Soktui and Abagaitui. Dr. Radde gives the following account of the habits of this animal as observed by himself and as obtained from the reports of the natives in 1856:-- “About the middle of June the doe produces generally two young ones which remain quiet for three days, but after that are strong enough to follow the mother wherever she goes. If caught when young they quickly become tame. Shortly after my arrival at Zagan-olui in May 1856 I saw a fawn of this Antelope feeding with the sheep and goats without requiring any particular attention. “In summer these Antelopes are seldom hunted because they are only occasionally to be found, but they are much pursued during the early winter. There are, however, but few good Antelope-hunters, especially amongst the Russians. Various methods are adopted to get within shot. So long as no snow has fallen the Antelopes usually proceed about midday in small flocks to the freshwater lakes, where they break the thin ice with their hoofs in order to drink. They select the same spot every day for this purpose, and there it is that the hunter makes his hiding-place. Driven on to the thin ice, the Antelopes often fall through and thus become an easy prey.
