Genus IV. STREPSICEROS. Type. _Strepsiceros_, Hamilton Smith, Griff. An. K. v. p. 365 (1827) S. capensis. _Calliope_, Ogilby, P. Z. S. 1836, p. 138 S. capensis. Large-sized Antelopes resembling _Tragelaphus_ and _Limnotragus_ in that the horns are spirally twisted and present only in the male; but differing from these two genera in that the horns are rounded behind at the base, with a scarcely appreciable external ridge, and form from two and a half to three complete turns with a more open spiral curvature. Further differing from _Limnotragus_, but resembling _Tragelaphus_, in the structure of the feet, which are adapted for progression on hard ground. Tail thickly hairy at the sides as in _Limnotragus_ and in most of the species of _Tragelaphus_. _Range of the Genus._ Eastern and Southern Africa from Abyssinia and Somaliland to Cape Colony, extending in Western Africa as far north as the Congo region. The two known species of this genus may be recognized as follows:— _a._ Height of adult male about four feet or over; horns with a bold and open spiral curvature and strongly diverging from the base; a mane of hairs running along throat in male; no white patches on the throat in either sex, and transverse body-stripes varying from four to ten. 130. _S. capensis._ _b._ Height of adult male only a little over three feet; horns with much less open curve and but little diverging from base; no throat-mane in the male; two white throat-patches in both sexes, and transverse body-stripes almost always more than twelve 131. _S. imberbis._ [Illustration: THE BOOK OF ANTELOPES, PL.
