The typical specimen of Oryx beatrix, as already mentioned, is in the collection of the British Museum, as is also the adult female transmitted to the Zoological Society by Col. Pelly. Besides these, the National Collection possesses a skeleton of a young female obtained on the Persian Gulf by Mr. B. T. ffinch, F.Z.S., and some skins and skulls collected in Muscat by Dr. A. S. G. Jayakar, C.M.Z.S. Specimens of the Beatrix Antelope are, however, excessively rare in European collections, and we are not aware that any of the continental museums have succeeded in obtaining specimens of it.

From what has been stated it is evident that the range of the Beatrix Antelope reaches from the shores of the Red Sea across Southern Arabia to Muscat. How far up the coast of the Persian Gulf it extends is uncertain, but the specimens stated by Pennant to have been brought to Ispahan from the Bahrein Islands had probably been obtained from the opposite mainland.

Our figure of this Antelope (Plate LXXXII.) was put upon the stone by Mr. Smit from a sketch prepared under Sir Victor Brooke’s directions by Mr. J. Wolf. This was probably taken from the same animal as that figured in the Zoological Society’s ‘Proceedings,’ as above mentioned.
