90 Mr. Gray on new Reptiles from Australia. 



low dorsal band, and the back is scarcely to be designated as granu- 

 lar. It is the second species of the genus, and only the second Toad 

 found in Australia, the other being Phreniscus australis, which I de- 

 scribed in the ' Proceedings of the Zoological Society ' under the name 

 of Bombinator australis. 



Uperoleia, Gray. Fam. Ranidse. 



Head large; palate quite toothless; upper jaw with small close 



teeth ; 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, oblong, roundish, and entire behind, 



This genus is most nearly allied to Leivperus 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. 



Uperoleia marmorata. Black and green marbled, leaving a trian- 

 gular 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 of very small, indistinct, oblong tubercles, with a dark 

 streak from the nostrils to the shoulder, enclosing the eyes, and 

 a white streak below it from the under side of the eye ; sides 

 purplish, with small white spots ; back of the thighs purple, 

 with two yellow spots ; belly and under side of thighs whitish, 

 granular, 



Var. 1. Back of thighs with one or two additional yellow spots. 



Var. 2. Back bluish gray ; back of the thighs with six or seven 

 small subequal yellow spots. 



Inhab, Western Australia, 



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

 toes webbed to the last joint ; (in spirits) gray-blue, with a 

 series of small oblong tubercles ; the sides purple-brown, with a 

 white streak from the under side of the eyes to the shoulders ; 

 sides of the belly and region of the vent purplish, with small 

 white spots ; the hinder side of the thighs purple-brown, with 

 three large oblong white spots ; belly and under side of thighs 

 granular ; chin white, brownish dotted ; palatine teeth in two 

 roundish groups between the internal nostrils, 



Inhab. Western Australia.
