the tympanum hid under the skin ; the toes of the fore and hind- 

 feet elongate, slender, quite free ; the ankle with a roundish 

 external and a small conical inner tubercle : the tongue small, ob- 

 long, roundish, and entire behind. 

 This genus is most nearly allied to Leiuperus of MM. Dumeril and 

 Bibron, with which it agrees in having no teeth on the palate, but it 

 differs from it in the tympanum being quite hid. 



The internal nostrils are some distance in front of the cross-ridge 

 on which the palatine teeth are generally placed. 



Uperolia marmorata. Black and green marbled, leaving a triangular 



greenish spot on the forehead, beneath lead-colour. 

 Inhab. Western Australia. 



Dr. Tschudi has formed a genus under the name of Crinia, which 

 appears by his characters to be nearly related to the above ; but MM. 

 Dumeril and Bibron (Erp. Gen. viii. 416) observed that the specimens 

 he described have two very small groups of teeth on the vomer. 



Hyla bioculata, Gray. Slender ; fore-toes quite free ; hinder toes 

 webbed to the last joint (in spirits). Grayish white, with a series

Hyla Adelaidensis, Gray. Slender ; fore-toes quite free, hinder toes

 the belly and region of the vent purplish, with small white spots ;
