Among the rarest of the tribe is the Midas argentatus, measuring only
seven inches in length of body. It resembles a little white kitten,--
being covered with long white silky hair. The tail, however, is
blackish, and the face nearly naked and flesh-coloured. The eyes, which
are black, are full of curiosity and mistrust; and one seen in
captivity--except when in the arms of its owner--shrank back and
trembled with fear, while its teeth chattered, and it uttered a
tremulous, frightened tone, at the approach of a stranger.
