JEVEROS (JEBEROS, JIBAROS, JIVAROS Or GIVAROS)  , a tribe of South American Indians on the upper Maranon, Peru, where they wander in the forests . The tribe has many branches and there are frequent tribal wars, but they have always united against a common enemy . Juan de Velasco declares them to be faithful, noble and amiable . They are brave and warlike, and though upon the conquest of Peru they temporarily submitted, a general insurrection in 1599 won them back their liberty . Curious dried human heads, supposed to have been objects of worship, have been found among the Jeveros (see Ethnol . Soc . Trans . 1862, W . Bollaert) .
