_Redunca nagor_, =Rüpp.= Verz. Senck. Mus. p. 38, Ost. p. 51 (1842). VERNACULAR NAME:--_Wonto_ of natives on the Gambia (_Gray_, fide _Whitfield_). Size decidedly smaller than in the previous species, the height at the withers only about 27 or 28 inches. Colour uniform bright fawn generally, without darker markings on the limbs; head and body quite alike. Tail comparatively short and little bushy, fawn above, white below. Horns very thick in proportion to the size of the animal, 5 inches in circumference at the base but only about 8 to 10 inches long. Their terminal portion is strongly turned forwards, a character most marked in rather young specimens before the long straight basal part has grown. Dimensions of a male skull:--Basal length 8·1 inches, greatest breadth 3·8, muzzle to orbit 5. _Female_ similar, but hornless. _Hab._ West Africa north of the forest region (Senegal and Gambia). The Reedbuck of West Africa was somewhat vaguely described by Buffon, in his ‘Histoire Naturelle,’ from a stuffed specimen in the cabinet of Adanson, which had been obtained from the island of Goree on the coast of Senegal. Fortunately Buffon added a tolerably recognizable figure of the “Nagor,” as he proposed to call it (from its fancied resemblance to the “Nanguer,” i. e. _Gazella dama_!), and taking this figure into consideration along with the locality, we can have little doubt as to its identity. In the first essay on the Antelopes, published in his ‘Miscellanea Zoologica,’ in 1766, Pallas suggested the name “_Antilope reversa_” for Buffon’s “Nagor”; but in his second essay on the same subject, issued in the ‘Spicilegia Zoologica’ in 1767, Pallas changed this name, which had been already used by Linnæus for another animal, to _Antilope redunca_. There can be no doubt, therefore, that _redunca_ is the proper specific name of the present species of _Cervicapra_, although this term has been applied by various authors, as will be seen by reference to our lists of synonyms, to three other species of the genus.
