PLATE XVI.—FIG. 4.

_Dentibus palatinis perpaucis, in fasciculis binis approximatis, pone

nares posteriores; lingua integrâ, oblongâ; tympano celato; pedibus

posterioribus non palmatis._

_Crinia Georgiana_, Tschudi Class. Batrach.

_Cystignathus Georgianus_, Bibr. Rept. VIII. p. 416.

This species, which formed the type of Tschudi’s genus _Crinia_, was

separated by him from _Cystignathus_ on account of the form of the

tongue, the nonappearance of the tympanum, the paucity of palatine

teeth, and the total absence of an interdigital membrane on the hinder

feet. These characters being either merely comparative or unimportant,

were not considered by Bibron as sufficient to warrant a generic

separation, and I have followed him in retaining the species amongst the

_Cystignathi_. It was first discovered by Messrs. Quoy and Gaimard at

King George’s Sound, in Australia, where it was also obtained by Mr.

Darwin. It is a beautiful species; the back being of a rich brown

colour, with a pale orange fascia extending along the sides from the eye

to the thigh, becoming bright orange on the flanks. Thighs and legs

banded with rich deep brown and bright orange.
