be observed on the chin, the back of the neck, shoulders, hips and legs; these are in sharp contrast with the broad white patches that mark its flanks and lower rump. The Lelwel hartebeest is a reddish tan. Coke's hartebeest is reddish to tawny in the upper parts, but has relatively lighter legs and rump. Lichtenstein's hartebeest is reddish brown, though the flanks are a lighter tan and the rump whitish. The Tora hartebeest is a dark reddish brown in the upper part of the body, the face, the forelegs and the rump, but the hindlegs and the underbelly are a yellowish white. The Swayne's hartebeest is a rich chocolate brown with fine spots of white that are actually the white tips of its hairs. Its face is black save for the chocolate band below the eyes. The shoulders and upper part of the legs are black. Fine textured, the body hair of the hartebeest is about long. The hartebeest has preorbital glands (glands near the eyes) with a central duct, that secrete a dark sticky fluid in Coke's and Lichtenstein's hartebeest, and a colourless fluid in the Lelwel hartebeest. Both sexes of all subspecies have horns, with those of females being more slender. Horns can reach lengths of ; the maximum horn length is , recorded from a Namibian red hartebeest. The horns of the western hartebeest are thick and appear U-shaped from the front and Z-shaped from the sides, growing backward at first and then forward, ending with a sharp backward turn. The horns of the red and the Lelwel hartebeest are similar to those of the western hartebeest, but appear V-shaped when viewed from the front. The Lichtenstein's hartebeest has thick parallel ringed horns, with a flat base. Its horns are shorter than those of other subspecies, curving upward then sharply forward, followed by an inward turn at an angle of about 45° and a final backward turn. The horns of Swayne's hartebeest are thin and shaped like parentheses, curving upward and then backward. The horns of the Tora hartebeest are particularly thin and spread out sideways, diverging more than in any other subspecies. Apart from its long face, the large chest and the sharply sloping back differentiate the hartebeest from other antelopes. The hartebeest shares several physical traits with the sassabies (genus Damaliscus), such as an elongated and narrow face, the shape of the horns, the
