We are not aware that any specimen of Angas’ Antelope has ever been brought to Europe alive, and it is by no means commonly met with in our museums. The British Museum contains an adult pair mounted, obtained in St. Lucia Bay by Mr. R. S. Fellowes in 1871, also specimens from the Pongolo River, Zululand, obtained by Mr. Eastwood, and from the Maputa River, obtained by Proudfoot. There are also in the National Collection the specimens from Nyasaland procured by Mr. Sharpe, Sir Harry Johnston, Mr. Crawshay, and Lieut. Oliver, of which we have made mention above. Finally, there is a good mounted pair of specimens obtained by Mr. Selous during his special expedition in quest of this Antelope. Our principal illustration of Angas’ Antelope (Plate XCII.) was put upon the stone by Mr. Smit, under the directions of the late Sir Victor Brooke, from sketches made by Wolf, and was probably taken from the mounted specimens then in the British Museum. At the same time the woodcut (fig. 106, p. 146), also containing figures of both sexes, was prepared by Mr. Smit. _November_, 1899. Genus III. LIMNOTRAGUS (nom. nov.). Type. _Hydrotragus_, =Gray=, Cat. Rum. B. M. p. 49 (1872) (_nec_ Fitz.)[11] L. spekii. Medium or large-sized Antelopes allied to _Tragelaphus_, but with rougher and shaggier coats, longer legs, and with horns which more nearly approach those of _Strepsiceros_, as they show a strong tendency to assume a third twist. Further, _Limnotragus_ differs strikingly from _Tragelaphus_ and _Strepsiceros_ in the structure of its feet, the hoofs being often nearly three times as long (measured along the front edge) as thick (measured along the margin of the pastern). Moreover, the skin which covers the back of the pastern is denuded of hair, and thick and horny, being practically of the same consistency as the upper rim of the posterior side of the hoof.
