After babyhood the Indians of Guiana are never seen naked. When
they change their single garment they retire. The women wear a
little apron, now generally made of European beads, but the
Warraus still make it of the inner bark of a tree, and some of
seeds. (Everard im Thurn, _Among the Indians of Guiana_, 1883.)

The Mandurucu women of Brazil, according to Tocantins (quoted by
Mantegazza), are completely naked, but they are careful to avoid
any postures which might be considered indecorous, and they do
this so skilfully that it is impossible to tell when they have
their menstrual periods. (Mantegazza, _Fisiologia della Donna_,
cap 9.)

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
