Next come the Rupicaprinae, which include several genera of mountain-dwelling ruminants, typified by the European chamois (Rupicapra); the other genera being the Asiatic serow, goral and takin, and the North American Rocky Mountain goat.
(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).
In the structure of its horns the North American white Rocky Mountain goat (Oreamnus) is very like a serow, from which it differs by its extremely short cannon-bones.
Possibly the Arctic musk-ox (Ovibos) may be connected with the takin by means of certain extinct ruminants, such as the North American Pleistocene Euceratherium and the European Pliocene Criotherium (see Chamois, Goral, Serow, Rocky Mountain Goat and Takin).
Three very characteristic ruminants, having some affinities with goats, inhabit the Himalaya; these are the " serow " (Nemorhaedus), " goral " (Cemas) and " tahr " (Hemitragus), the last-named ranging to rather high elevations.
