 swampy country affected by many. T. gratus and T. spekei are larger forms; the Boschbok, T. sylvaticus, is smaller.

The Kudus, genus Strepsiceros, have more markedly twisted horns, which are absent in the female. The body is vertically striped with white. The largest species is S. kudu; a smaller form, S. imberbis, is from Somaliland.



The last genus of this section or sub-family is the African Eland, genus Oreas (which it appears should be spelt Orias). The Elands are perhaps more Ox-like in appearance than the other members of this group, and in both sexes have horns, in which the spiral twisting is more close. Orias canna is the name of the common Eland. O. livingstonii has been applied to an East African variety, which has thin and faint lateral stripes like the other members of the group to which it belongs.

The genus Boselaphus includes only B. tragocamelus, the Nilgai, which is purely Indian in range. The female is hornless, and the horns of the male are smooth and not long.
