By the kind permission of Lord Derby we now give an exact copy, slightly reduced in size, put upon the stone by Mr. Smit (Plate LXXVIII), of Waterhouse Hawkins’s drawing of the “Dacris,” which forms one of the figures of plate 5 of the second volume of this valuable series, and is stated to represent an adult female. This figure will be observed to differ from that of the male (Plate LXXVII.) in its much lighter and more reddish colouring, and especially in the longer ears of the Gambian animal. One of the young specimens brought home by Whitfield is now stuffed in the Derby Museum at Liverpool. As we learn from the label, it died in London on its way to Knowsley. More recently heads of this Antelope have been obtained on the Gambia by Dr. Percy Rendall, F.Z.S., and by Sir R. B. Llewelyn, the present Governor. The latter were exhibited by Sclater at a meeting of the Zoological Society on May 3rd, 1898[8], when attention was called to the large number of fine Antelopes that occur in the Gambia Colony, and to the desirableness of procuring further information about them. According to the notes supplied to us by Sir R. B. Llewelyn, the Roan Antelope, which is the “_Da Kevoi_” of the Mandingos, is found in some places in Jara and Kiaung, and is common in Eastern Niammina. The horns in question are those of a not fully adult animal, measuring 26½ inches along the curvature. They do not present any noticeable features to distinguish them from those of _Hippotragus equinus typicus_ of South Africa. The existence of this Antelope in West Africa has been further confirmed by Herr Matschie, who has included it in his list of Mammals of the German Protectorate of Togo, on the Gulf of Guinea, where it occurs on the uplands of the interior. Herr Matschie kindly informs us that the Berlin Museum has received from that locality a defective head and skin without horns from Misa-höhe, transmitted by Herr Baumann, and two skulls of females from Bismarckburg (_Kling_ and _Conrad_). In the collection of the British Museum there are also a scalp and skull of a young male of the Roan Antelope obtained at Balaga, Beaufort Island, on the Niger, and presented by Capt. A. J. Richardson. Lastly, we may add that there is a fine young male Roan Antelope now living in the Zoological Garden, Antwerp, which is stated to have been received from Senegal, and, if so, would probably belong to the subspecies now under consideration.
