The horns practically form a single simple or slightly lyrate curve in all the species, except _D. hunteri_, and in this, although there is a double sigmoid curve, no approximation is shown to the peculiarly abrupt double curvature characteristic of _Bubalis_. _Range of the Genus._ Africa south of the Atlas. As in the previous genus, the species of _Damaliscus_, seven in number, may be divided into groups based on the curvature and direction of the horns, as follows:-- A. Horns with a double curve, slanting outwards and upwards, then bending slightly downwards almost at once, while their long points are again directed upwards 1. _D. hunteri._ B. Horns evenly curved backwards or slightly lyrate; the tips only recurved upwards. _a._ No white blaze on face 2, 3, 4. _D. korrigum_, _D. tiang_, _D. jimela_. _b._ Face with a white blaze 5, 6. _D. pygargus_, _D. albifrons_. C. Horns starting laterally outwards, with a single lunate curve upwards and backwards 7. _D. lunatus._ [Illustration: THE BOOK OF ANTELOPES. PL.

Facial hairs wholly reversed upwards from the muzzle to the horns. Colour uniform rufous, with no darker markings anywhere, on face, chin, or limbs, and the caudal crest even, black in every other species, is here wholly white. On the face, however, there is a well-defined white line passing from one eye to the other across the forehead. Lower part of rump not markedly lighter than upper. Skull slender and lightly built. Basal length 12·9 inches, greatest breadth 5·2, muzzle to orbit 9·1.
