On crossing the high range north of the Hindu Koosh into Eastern Turkestan a Gazelle very similar to the Persian Gazelle is met with. Six examples of this form were obtained by the naturalists of the Second Yarkand Mission in 1873–74, and were described by Dr. Blanford in his memoir on the Mammals of that Mission. Dr. Blanford says that it is perhaps a question whether the Eastern Turkestan Gazelle should not be raised to the rank of a species. It differs principally from the typical form in the very much darker markings on the face and in the much smaller degree to which the horns diverge. The size appears rather larger than that of the typical Persian form. But as there are some variations in the face-markings of Persian specimens, Dr. Blanford has considered it better to regard the Yarkand race as only a variety, which he has proposed to call _Gazella subgutturosa yarkandensis_. Of this subspecies an excellent coloured figure, drawn by Smit, is given in the above-named work. It represents both sexes, and shows the black markings on the face very distinctly. As pointed out by Dr. Blanford, it is nearly certain that the Gazelle to which Shaw refers, in his volume on ‘High Tartary, Yarkand, and Kashgar’ (page 221), as having been brought to him at Yarkand, and of which he says the Yarkand name is “_saikeek_,” was of the present species--that is, of the local form _Gazella subgutturosa yarkandensis_. We have already mentioned the four living examples of this Gazelle brought to London by Dr. Aitchison and presented to the Zoological Society’s Collection. These, however, were not the first specimens of this animal brought to England alive. As long ago as 1852 females of the present species were obtained from Bussorah on the Persian Gulf and presented to the Society by Alderman Finnis, and in 1869 examples from the same country were given to the collection by the late Mr. T. K. Lynch, F.Z.S. Other specimens, mostly from the same country, were received in subsequent years[6]. The examples of this animal just spoken of as being the first to arrive in England formed the subjects of a beautiful drawing by Mr. Wolf, a coloured lithograph taken from which has been published in the first volume of Wolf and Sclater’s ‘Zoological Sketches’ (plate xxii.). Our figures of this species for the present work (Plate LV.) have been prepared by Mr. Smit from the descendants of the animals brought by Dr. Aitchison from Northern Persia, now living in the Society’s Gardens.
