The Bushbucks of the typical section of the genus _Tragelaphus_ appear to be spread all over Africa south of the Sahara, wherever wooded districts suitable for their mode of life are met with. But although they are all nearly similar in general structure they vary much in their markings and other minor characters, and it is an exceedingly difficult task to decide how far these differences should be regarded as specific or subspecific, or in some cases as merely individual variations. A much larger series of specimens from the various localities in the wide area over which this animal ranges than we can yet command is necessary before any certain conclusions can be arrived at on this subject. Meanwhile we propose to follow, as probably approximately correct, the view already put forward on this group by Thomas in his article on the _Tragelaphi_, published in the Zoological Society’s ‘Proceedings’ for 1891, merely elevating the four forms there treated of as subspecies to the rank of species. Of these four species thus recognized we have already treated of one—_Tragelaphus decula_, which appears to be a somewhat isolated form only met with in Abyssinia and the immediately adjacent districts. We have now come to the true _T. scriptus_, which, on the contrary, seems to have a very wide distribution under its various phases. The “Harnessed Antelope,” as it is usually called in English, was first discovered in Senegal by the celebrated naturalist and traveller Adanson, who visited that Colony in the middle of the last century, and communicated many of his notes and specimens to Buffon. The latter described and figured it in his ‘Histoire Naturelle’ under the name “_Le Guib_” which Adanson gave as its native name in Senegal, stating that it is found in the woods and plains of the country of the Jaloufs and on the Senegal River. From Senegal also living specimens of both sexes of this Antelope were subsequently received at the Jardin des Plantes, and figured under the same name by F. Cuvier and Geoffroy St.-Hilaire in their great work upon Mammals. Pallas established his “_Antilope scripta_” upon Buffon’s “_Guib_,” stating that he had not himself met with examples of it. There can be no doubt, therefore, that this particular local form is entitled to be called _Tragelaphus scriptus_. Like most of the Senegalese mammals, it also occurs on the Gambia, where Whitfield, and, in more recent days, Dr. Rendall procured specimens which are now in the British Museum. Descending the West-African coast we find the same species also recorded from Liberia, where Herr Büttikofer and his fellow-explorers of that Republic, as recorded by Dr. Jentink, met with it in many localities and obtained a good series of specimens of it for the Leyden Museum.
