In the ‘Gleanings from the Knowsley Menagerie’ are contained two figures of this animal: plate vi. fig. 3 gives a full-sized figure of what is apparently a female of this species, and plate ix. represents the heads of both sexes. Both of these plates are marked as drawn by Waterhouse Hawkins from specimens living at Knowsley in 1843. Several specimens of the Coquetoon, as this Antelope is sometimes called, have also been received by the Zoological Society, but have not proved to be long-lived in this country. The first recorded specimen was obtained in 1861, and others were subsequently acquired in 1867, 1879, and 1880. These were all obtained from dealers and had no definite localities attached to them. But we are able to supply some indications of the range of this species from museum specimens. In the British Museum, besides Whitfield’s stuffed specimen from the Gambia already alluded to, there is the skull of an adult animal from the same locality obtained by Sir Gilbert Carter, and a young skull, which has probably been correctly referred to this species from the Niger, obtained by Surgeon Baikie. In the Leyden Museum, as we find by Dr. Jentink’s Catalogue, there is an adult female specimen procured at Dabocrom, in Ashantee, by the collector Pel, and an adult male from Sierra Leone received from the Bremen Museum. In reference to Pel’s specimen, Temminck has informed us that this species is rare on the Guinea coast, but more common in the forests of Sierra Leone. We also find this species recorded by Herr Matschie as one of the Antelopes met with by the collectors of the Berlin Museum in the German Protectorate of Togoland. We may therefore conclude that the Red-flanked Duiker inhabits the whole coast-land of Western Africa between the British Settlement of Gambia and the River Niger. Our figure of this species (Plate XIX. fig. 1) was prepared under Sir Victor Brooke’s direction, very probably from one of the specimens in the Liverpool Museum. _May, 1895._ [Illustration: THE BOOK OF ANTELOPES, PL.
