As regards the name to be used for this local form or subspecies of the Roan Antelope a few words are necessary. Gray, in his ‘Catalogue of the Ruminants,’ published in 1872, proposed to call it “_koba_”—no doubt because of Whitfield’s assurances that it was the “Kob” or “Koba” of the Jolliffs, and, as will be seen by our list of synonyms, several subsequent authors have followed Gray’s lead. But we have already fully discussed the question of this much-vexed name (see Vol. I. p. 60), and have shown that it is hopeless to attempt to refer the “Koba” of Buffon satisfactorily to any of the species with which it has been identified. It follows that the Latin specific term “_koba_,” founded on Buffon’s name, must also fall to the ground. Under these circumstances we propose to designate the western form of the Roan Antelope _Hippotragus equinus gambianus_, as being the representative of this species in the Gambia. South of Togo, along the West-African coast down to the Congo and in the great Congo valley itself, we are not aware of the Roan Antelope ever having been met with; nor is it likely to occur there, as the uniform dense forest which covers these districts would be little suited to its habits. But when we proceed further south to Mossamedes and the interior of Angola, where the country becomes drier and more open, the Roan Antelope is again found. Dr. Jentink mentions it in his article on the mammals collected in Mossamedes by Mr. P. J. van der Kellen (Notes Leyd. Mus. ix. p. 173); and Prof. J. V. Barboza du Bocage includes it in his catalogue of the Mammals of Angola, published in 1892, as having been received from Golungo Alto in the interior, where, along with the Sable Antelope, it is known by the native name of “Palanca” or “Malanca” (Jorn. Ac. Sc. Lisboa, 2, ii. p. 26). We presume that the Angolan representative of the Roan Antelope will be found to belong to the typical South-African form _Hippotragus equinus typicus_. The specimens of the Roan Antelope in the British Museum consist of a mounted adult male and a young one, and the skeleton of a male, from Mashonaland, presented by Mr. F. C. Selous (exhibited in the gallery); an adult male presented by Sir Andrew Smith, being the specimen figured in his ‘Illustrations,’ as above referred to; a female presented by Lord Derby; and a skin and skull of an adult from Lake Mweru, presented by Mr. Crawshay. There are also several pairs of horns, one of which was received from Dr. Burchell. These specimens all belong to the typical form. Of the East-African _H. equinus rufo-pallidus_ the British Museum has only the scalp and skull from Machakos (_Dr. Hinde_) above referred to. [Illustration: Fig. 90.
