REDUNCA. _Eleotragus_, =Gray=, List Mamm. B. M. p. 165 (1843) C. ARUNDINUM. 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:-- A. Height about 36 inches. Basal length of skull about 10 inches. 70. _C. arundinum_. B. Height about 31 inches. Basal length of skull about 9 inches. 71. _C. bohor_. C. Height about 28 inches. Basal length of skull about 8 inches. _a._ Horns strongly hooked at the tips 72. _C. redunca_. _b._ Horns not hooked terminally. _a´._. S. Africa 73. _C. fulvorufula_. _b´._. E. Africa 74. _C. chanleri_. [Illustration: THE BOOK OF ANTELOPES, PL. XLIII. _Wolf del. J. Smit lith._ _Hanhart imp._ The Reed Buck. CERVICAPRA ARUNDINUM. _Published by R. H. Porter._] 70.
