This species is based upon an old mounted specimen in the Darmstadt Museum which was obtained years ago by Harnier on the Bahr-el-Gebel between 6° and 7° N. lat. The horns have eighteen rings and are nearly parallel; they measure from base to tip 35·4 centim. in a straight line. The ground-colour of the fur is yellow; the eye-region, a circular mark in front of the ears, rim round the nostrils, under lips, under neck, whole under surface, and inner sides of legs are white; the sides of the head, the whole body and a broad band across the breast, the hind margins of the shoulders, and thighs are yellow; an oval nose-spot, a broad band from the side of the neck, bordering the white breast, over the shoulders down to the hoofs are black, as are the groins and the hinder feet; a white ring surrounds the hoofs. Cobus vardoni loderi. _Cobus vardoni loderi_, =Lyd.= P. Z. S. 1899, p. 983. On a skull and horns in the collection of Sir E. G. Loder, F.Z.S., from an unknown locality (of which a figure is given), Mr. Lydekker bases this subspecies of the Poku (_cf._ Bk. of Ant. vol. ii. p. 141). A somewhat similar specimen was obtained by Mr. Smitheman near Lake Bangweolo, and it is thought possible therefore that these specimens may belong to _C. smithemani_, described in the same paper. Genus CERVICAPRA. (Vol. II. p. 155.) Cervicapra thomasinæ. _Cervicapra thomasinæ_, =Scl.= P. Z. S. 1900 (May 8th). Under this name Sclater has recently described and figured a species of Reedbuck, met with in Nyasaland, which he has characterized as follows:—“_C._ quoad formam _C. arundinum_ fere similis, sed colore albo, in dorso cineraceo et pedibus antice fulvo-brunneis, ut videtur, satis diversa: alt. ad humeros 35 poll.—_Hab._ in ripis Laci Nyasæ, Afr. or.” Cervicapra fulvorufula subalbina. _Cervicapra fulvorufula subalbina_, =Kirby=, P. Z. S. 1897, p. 897. This is either a partially albino variety or a local form of _Cervicapra fulvorufula_, discovered by Mr. F. V. Kirby, F.Z.S., on the mountains of the Lydenburg district of the Transvaal. It differs from typical specimens in having the legs white from the knees down, white hoofs, a pure white tail above and beneath, a white spot on the forehead, and a more or less clearly defined white stripe down the back of the neck and along the dorsal line. There are two specimens of this Antelope in the British Museum, presented by Mr. Kirby. Genus LITHOCRANIUS. (Vol. III. p. 227.) Lithocranius sclateri. _Lithocranius sclateri_, =O. Neumann=, SB.
