(See ANTELOPE, CHAMOIS, GORAL, ROCKY MOUNTAIN GOAT, SEROW and TAKIN.) Under the indefinable term "antelope" (q.v.) may be included the seven remaining sections, namely Tragelaphinae (kudu and eland), Hippotraginae (sable antelope and oryx), Antilopinae (black-buck, gazelles, &c.), Cervicaprinae (reedbuck and waterbuck), Neotraginae (klipspringer and steinbok), Cephalophinae (duikers and four-horned antelopes) and Bubalinae (hartebeests and gnus).
A still more aberrant gazelle is a small North-East African species known as the beira (Dorcatragus melanotis), with very short horns, large hoofs and a general appearance recalling that of some of the members of the subfamily Neotraginae, although in other respects gazelle-like.
The Neotraginae (or Nanotraginae) form an exclusively African group of small-sized antelopes divided into several, for the most part nearly related, genera.
