_Caput subrotundum planum. Linguæ magnâ circularis, posticè libera.
Dentes palatini in lineâ transversâ, parum interruptâ, dispositi.
Tympanum distinctum. Digiti subdepressi, ad apicem obtusi, haud
expansi; anteriores ferè liberi; posteriores ad basin membranâ
connexi, et marginati. Femora multò glandulosa._
A genus nearly allied to _Hylodes_, from which, however, it may at once
be distinguished by the palmure of the hinder toes—which in _Hylodes_
are entirely free—and by the absence of even the slightest dilatation of
their extremities; offering another example of an osculant form between
the HYLIDÆ and the RANIDÆ.
