BUSHBUCK (Boschbok)  , the South African name of a medium- sized red antelope (q.v.), marked with white lines and spots, belong- ing to a local race of a widely spread species, Tragelaphus script us . The males alone have rather small, spirally twisted horns . There are several allied species, sometimes known as harnessed antelopes, which are of a larger size . Some of these such as the situtunga (T . spekei) have the hoofs elongated for walking on swampy ground, and hence have been separated as Limnotragus .
