The Indians of Central Brazil have no "private parts." In men the little girdle, or string, surrounding the lower part of the abdomen, hides nothing; it is worn after puberty, the penis being often raised and placed beneath it to lengthen the prepuce. The women also use a little strip of bast that goes down the groin and passes between the thighs. Among some tribes (Karibs, Tupis, Nu-Arwaks) a little, triangular, coquettishly-made piece of bark-bast comes just below the mons veneris; it is only a few centimetres in width, and is called the _uluri. In both sexes concealment of the sexual mucous membrane is attained_. These articles cannot be called clothing. "The red thread of the Trumai, the elegant _uluri_, and the variegated flag of the Bororó attract attention, like ornaments, instead of drawing attention away." Von den Steinen thinks this proceeding a necessary protection against the attacks of insects, which are often serious in Brazil. He does think, however, that there is more than this, and that the people are ashamed to show the glans penis. (Karl von den Steinen, _Unter den Naturvölkern Zentral-Brasiliens_, 1894, pp. 190 et seq.) Other travelers mention that on the Amazon among some tribes the women are clothed and the men naked; among others the women naked, and the men clothed. Thus, among the Guaycurus the men are quite naked, while the women wear a short petticoat; among the Uaupás the men always wear a loin-cloth, while the women are quite naked. "The feeling of modesty is very developed among the Fuegians, who are accustomed to live naked. They manifest it in their bearing and in the ease with which they show themselves in a state of nudity, compared with the awkwardness, blushing, and shame which both men and women exhibit if one gazes at certain parts of their bodies. Among themselves this is never done even between husband and wife. There is no Fuegian word for modesty, perhaps because the feeling is universal among them." The women wear a minute triangular garment of skin suspended between the thighs and never removed, being merely raised during conjugal relations.
