The New International Encyclopædia/Blaubok, or Bluebuck

BLAUBOK, blou′bōk, or Bluebuck (Dutch blauwbok, blue buck). A large hippotragine antelope (Hippotragus leucophæus) of South Africa, distinguished by its glaucous hue. Its long, stout horns sweep back from its forehead in a sabre-like curve, and are effective weapons. Closely related are the magniticent, jet-black sable antelope (Hippotragus niger), the equine antelope (Hippotragus equinus), and Baker's antelope (q.v.) (Hippotragus Bakeri). All have been growing rare, and it is feared that since 1900 the blaubok has been extinct.
