DESCRIPTION.—Head depressed, broad, rounded. Nostrils small, placed
near together. Eyes large, opening considerably upwards. Tongue
nearly round, the posterior part free for about one-third of its
length. Palatine teeth placed in two small oval groups, placed
obliquely, between the posterior nostrils, separated from each
other by a considerable space. Tympanum small, nearly round. Limbs
of moderate length. The toes on all the feet depressed, slender,
the terminal dilatation very small, transverse, truncated; those
of the fore feet connected at the base only, those of the hinder
to the union of the first and second phalanges; of those of the
fore feet the third is the longest, then the fourth, the second,
and the first; of the hinder the fourth is the longest, then the
third and fifth equal, then the second and the first. There are
some minute scattered glands on the posterior part of the thighs.
The only specimen in Mr. Darwin’s collection is in so bad a condition,
that it is impossible to say with any certainty what is its natural
colour. It is brown above, with a lighter band across the head between
the eyes, and there are traces of a longitudinal line down the back; the
limbs are banded with brown and brownish yellow; the under parts are
pale, dotted with brown.
