Head of Gems'bok
This illustration shows a head of a Gems’bok. A Gems’bok (Oryx Gazella) is a species of South African antelope. It is a heavy, stout animal, about the size of a stag, with rough, reversed hair on the neck and along the ridge of the back; large pointed ears; and almost perfectly straight horns in the plane of the forehead, little diverging, and ringed for about half their length. These horns have been known to reach a length of 47 1/2 inches. The gems’bok was, at one point, close to extinction.
