Our coloured figure of this Antelope (Plate II.) has been drawn by Mr. Smit from the mounted specimen in the British Museum, obtained by Captain Swayne on the Haud plateau of Somaliland. The woodcut (fig. 3, p. 24) gives a front view of the first skull and horns received from Captain Swayne, upon which Sclater based the species. This specimen is now likewise in the National Collection. _May, 1894._ [Illustration: THE BOOK OF ANTELOPES. PL. III. _Smit lith._ _Hanhart imp._ Cokes Hartebeest. BUBALIS COKEI. _Published by R. H.
