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. _May,_ 1898. [Illustration: THE BOOK OF ANTELOPES, PL. LXVI. _Wolf del.
