_Femoribus posticè glandulosis; digitis posticis brevitèr palmatis._
This species agrees in many respects with _Litoria Americana_ of Bibron.
It differs, however, in the toes being much less palmate, at least
according to the generic character given by that excellent naturalist,
and in the existence of numerous thick glands on the posterior part of
the thighs. The very slight degree to which the extremities of the toes
are dilated in the other species of this genus, and which would at first
sight lead to their allocation amongst the Raniform rather than the
Hyliform group, is in the present species even more strongly exhibited;
and it can scarcely be said that any dilatation exists at all.
The colours in the only specimen brought by Mr. Darwin are much
obscured. The upper parts are apparently of an uniform brown, the under
parts whitish, dotted with brown.
It was taken by Mr. Darwin at Concepcion, in Chile.
