- a large antelope, Oryx beisa, with distinctive black striping on its neck and face, a conspicuous black stripe separating its gray coat from its white underside, and thin, nearly straight, ringed horns that reach a length of about 31 inches (79 centimeters) on both the males and females: it has two subspecies, one found throughout the Horn of Africa, and the other found in southern Kenya and northeastern Tanzania, both of which were once thought to be subspecies of the gemsbok and which are now classified as near threatened.
