arrival I slipped him at the Goas, but the wounded one seemed to recover completely, and it soon distanced the greyhound. The one I had killed had a very beautiful pair of horns.” Besides the experiences of the travellers and sportsmen from the Indian side, the only published record concerning the Tibetan Gazelle, so far as we know, is that of the great Russian explorer Przewalski, who, after treating of the “Orongo” of Northern Tibet (_Pantholops hodgsoni_), mentions the present species as being found in the same district, and there known to the Mongols as “Ata-dzeren,” or Little Antelope[4]. Przewalski, who met with this animal near the headwaters of the Tatong-gol, in Northern Tibet, and, as he believes, also in the highlands of Kan-su in China, describes its habits as follows:-- “Like the Orongo it frequents elevated plains, preferring, however, the valleys in the mountains where water is abundant. Yet its habits are very different from the Orongo’s, and it is without exception the most graceful and the swiftest of the antelopes of Mongolia and Northern Tibet. It generally moves in small herds of from five to seven (seldom as many as twenty), though solitary males are often seen. It is extremely wary, especially in those districts where it has learnt to fear man; on the banks of the Muruiussu it is a little less timid. Its swiftness is amazing; it bounds along like an india-rubber ball, and when startled seems absolutely to fly. During their breeding-season, which begins towards the close of December and lasts a month, the males chase one another from their herds, but we never saw them fighting like the Orongo, nor did we ever hear them utter any sound other than a snort on seeing a man; and the does when startled gave a short loud cry. They scrape themselves trenches a foot deep, in which they lie at night (and probably during the day), and in these we found heaps of their droppings. “This little antelope is more difficult to shoot than the Orongo, besides being much scarcer and extremely tenacious of life. Its ashy-grey colour, exactly resembling the soil, renders it almost invisible at a distance, and it is only by its conspicuous white rump, and its snort, that you are able to discover its presence.” There are many specimens of this Antelope in the British Museum presented by Mr. Hodgson, amongst which is the type of the species. There are also in the National Collection skulls from Kumaon and other localities presented by Mr. A. O. Hume, C.B.; from the Changchenmo Valley, Ladak, presented by Mr. R. Lydekker; and from the confines of Tibet north of Sikim, collected by Mandelli and presented by Dr. W. T. Blanford, F.R.S. There is also a good series of specimens of this Gazelle in the Museum of the Academy of Sciences of St. Petersburg, obtained by the Russian explorers in Northern Tibet and in the mountains of Nan-shan.
