(From specimens in B. M.)

Instead of the massive, nearly straight, non-lyrate horns of G. arabica, Sir Victor showed that the new species had rather slender horns, compressed from side to side and distinctly lyrate, with their points turned boldly forwards and inwards. In general appearance also the Muscat Gazelles differed from G. arabica in their long and soft coats of a silvery-grey colour, instead of the short close-set pelage of a rich grizzled bay. From G. dorcas, to which they bore more resemblance, the Muscat species was recognizable by its smaller size, its different colour, and by the intensity of the facial and lateral markings.

Sir Victor’s paper on this new Gazelle was illustrated in the ‘Proceedings’ by a good coloured plate drawn by Keulemans, in which, however, the general colour is made rather too dark.

In 1874 a second male specimen of this well-marked species was presented to the Zoological Society’s Menagerie by Mr. J. H. Bainbridge, and in October 1881 a pair of the same Gazelle were presented by the late Lord Lilford. These last bred a young one, which was born in the Society’s Gardens on the 6th of March, 1882.

No more examples of the Muscat Gazelle reached the Regent’s Park after this date until 1894, when a female of this species was obtained “in exchange,” and a pair were received “on deposit” from the Hon. Walter Rothschild, F.Z.S. The male of this pair is still living in the Society’s Menagerie.

The only other specimens of the Muscat Gazelle ever received in Europe, so far as we know, are five examples in the British Museum, presented to that Institution by Dr. A. S. G. Jayakar, of whose many and valuable contributions to science we have already spoken[14]. Among the several consignments of the Mammals of Oman sent home by Dr. Jayakar, of which Thomas has given an account in the Zoological Society’s ‘Proceedings’ for 1894, were five examples of this Gazelle collected in 1892 and 1893 in several localities in Oman—Khode and Barkah-al-moze, and in Sharkeeyeh, the eastern part of that country. These specimens agree very closely with the type of the species as described by Sir Victor Brooke, which is also in the National Collection.

Our figures of both sexes of this Gazelle (Plate LXV.) have been prepared by Mr. Smit from the specimens in the British Museum.
