BURUN. The Burun, inhabiting the extreme southern portion of the Sudan and the hills north of the Khor Yabus, are a tall race whose men go naked and whose women wear a small apron. Knowledge of the Burun is limited to measurements and photo graphs taken by the late Dr. Pirrie. These people differ in habits and customs from the river negroids, live in small widely separated huts, have no cattle, use the bow and poisoned arrows and carry throwing sticks. Measurements and photographs suggest that the Burun nearly approach the Nuba of southern Kordofan.
