We have, however, no evidence at present of the occurrence of the Lechee anywhere further north than the Mweru district. The specimens obtained by Petherick on the White Nile and assigned to Cobus lechee by Gray are, as already mentioned, properly referable to C. leucotis.

Our figure of this Antelope has been drawn by Smit from a sketch made by Wolf, and taken, we believe, from the original typical specimen now in the British Museum.

December, 1896.

Similar in essential characters to Cobus, but size smaller, build lighter, tail more bushy, and a glandular spot, naked or short-haired, present on the side of the head beneath the ears. Skull light, with large anteorbital vacuities; no anteorbital fossæ; premaxillæ not reaching the nasals. Horns of median length, evenly curved upwards and, in some species, forwards; not present in the females.

Distribution. Africa, south of the Sahara (not found in the forest-districts of Western Africa).

The species of Cervicapra are remarkably closely allied, and differ in fact by scarcely any striking characters but size. The strong curvature of the horns in some of the species would seem to be an important character, were it not that in C. bohor there is much variation, even in specimens from the same locality. Darker markings on the face and crown seem also to be too variable to afford good distinctive features. We are therefore reduced to dividing the species mainly according to size, as follows:—
