VERNACULAR NAMES:--_Rhozal_ or _Hemar_ of Arabs of Algeria (_Pease_); _Ghasala_ of Arabs (_Tristram_). Size small; height at withers 21–22 inches. General colour pale fawn, rather variable in tone. Facial markings distinct; central band rufous fawn; streaks from eye to mouth brownish fawn, contrasting with the white bands between them. Ears long, whitish fawn behind. Light lateral band present, but not strongly marked; dark lateral band brown, considerably darker than the back, but not black. Pygal band indistinct. Knee-tufts present. Skull rather lightly built; nasals narrow; anteorbital fossæ large and deep. Basal length 6·6 inches, greatest breadth 3·35, muzzle to orbit 3·55. Horns of medium length, but quite different in their shape to those of any other species, although the difference is not very easy to explain. Primarily it may be said that they are flattened laterally, are evenly divergent as they curve backwards, reapproach terminally, and have their tips bent upwards in a well-marked curve. But in addition to this simple curvature, the middle portion of each horn is lyrated outwards, so that the longest diameter of the horn-section above is quite in a different plane to what it is at the base; it is in consequence of this lyration that the horns, apart altogether from the curved tips, reapproach each other terminally, while in all other species such reapproach as occurs is entirely due to the incurving of the tips. The lyration and curvature of the horns are well shown in our figure (p. 108), and a comparison of it with those of _GG. przewalskii_, _marica_, _tilonura_, and _soemmerringi_ will show how different the method of terminal approximation is in this species as compared with them. _Female._ Similar to the male, but horns slender, slightly curved, from one-half to three-fourths the length of those of the male.
