In 1868 Sclater gave an account before the Zoological Society of London of a young male Equine Antelope of this form which he had observed in the King of Italy’s Menagerie, and illustrated it by exhibiting a coloured photograph of the animal, which was subsequently reproduced in the Society’s ‘Proceedings.’ The animal had been received from Dr. Ori, the King’s agent at Khartoum, and on its death was deposited in the Royal Zoological Museum of Turin. Sclater’s paper was supplemented by some field-notes on this Antelope contributed by Sir Samuel Baker, who also sent for exhibition the fine pair of horns of the typical specimen described by Heuglin, then in his collection. A figure of them is likewise given in Sclater’s article in the ‘Proceedings,’ which, by the kind permission of the Society, we are enabled to reproduce in these pages (fig. 89, p. 25). On Nov. 24th, 1878, the Zoological Society of London acquired a young male Equine Antelope from Mr. C. Hagenbeck, who stated that he had received it along with other animals from Upper Nubia. If this statement was correct, which there is no reason to question, this animal was, no doubt, an example of _Hippotragus equinus bakeri_, although it was never recognized as such. It lived in the Regent’s Park Gardens until February 23rd, 1889. There was also, about twenty years ago, an Equine Antelope, obtained from the same source, living in the Zoological Garden at Berlin. Mr. Clarence Bartlett has kindly lent us an excellent water-colour drawing of this specimen taken by the late Stanley Wilson. It represents, no doubt, the same local form of this Antelope. Mr. Hagenbeck informs us that the Berlin specimen was also received by him in one of his consignments from the Egyptian Sudan. That a representative of the Equine Antelope is likewise found in West Africa on the open country traversed by the Upper Gambia has been known since Whitfield, as recorded by Gray in 1852, brought home specimens of its head and horns. Gray did not then consider these to indicate any difference from the Cape specimen of this species in the British Museum. In a subsequent journey Whitfield also brought home for the Derby Menagerie two, or perhaps three, living examples of this Antelope. These were figured by Waterhouse Hawkins in three water-colour drawings forming part of the two volumes of original sketches by Waterhouse Hawkins and Wolf which are now in the Library at Knowsley, and which, by the kind permission of the present Earl of Derby, were exhibited and described by Sclater at the meeting of the Zoological Society on December 15th, 1896[7]. From the MS. notes written on these three drawings we learn that they were made on board the S.S. ‘African’ on Sept. 11th and 12th, 1848, and represent the adult female and young male of this Antelope—the “_Dacris_” of Whitfield.
