GUATUSO, an almost extinct Indian tribe dwelling on the forest-covered plains of San Carlos in northern Costa Rica. An aura of romance, now dispelled, has credited them with white skins and red hair. Their tongue is a Chibchan dialect, and their culture is of South American type.
See Karl Sapper, "Ein Besuch bei den Guatuso in Costa Rica," in Globus, Band. lxxvi. (Braunschweig, 1899).
