HIPURNIAS, a tribe of South American Indians, 2000 or 3000 in number, living on the river Purus, western Brazil. Their houses are long, low and narrow: the side walls and roof are one, poles being fixed in the ground and then bent together so as to meet and form a pointed arch for the cross-sections. They use small bark canoes. Their chief weapons are poisoned arrows. They have a native god called Guintiniri.
