Dr. A. Gunther on Australian Batrachia. 313 



The length of the body is more than the distance between vent and 

 metatarsal tubercles. Upper parts reddish ohve, with a double series 

 of irregular blackish spots along the back ; a black band runs from 

 behind the eye along the side of the body towards the loin, a blackish 

 streak along the canthus rostralis. Lower parts whitish.

Having found in the collection of the British Museum a specimeu 

 of Pterophrynus verrucosus, Lutken, I convinced myself that the 

 slight swelling of the skin between the angle of the mouth and the 

 shoulder is not produced by an accumulation of glands, so as to 

 deserve the name of a parotoid. The processes of the sacral ver- 

 tebra are so slightly dilated, that they might be described as cylin- 

 drical ; however, each process terminates in a cartilage, which is 

 very distinctly dilated. On com{)aring this Frog with the Camario- 

 lius of Peters, I came to the conclusion that both these genera must 

 be united ; for although Professor Peters describes the processes 

 of the sacral vertebra as narrow, I find them in Camariolitts varius, 

 Peters, as slightly dilated as in Pterophrynus. Probably any one 

 who had no opportunity of observing the following species would 

 have overlooked the dilatation of those processes in the species 

 mentioned. P. Itevis has them very distinctly dilated, and P. affinis 

 and /'. tastnaniensis are, in this re8j>ect, intermediate between these 

 extreme forms. They form only one genus, which, perhaps, must 

 be still further extended ; for, whilst none of the species mentioned 

 are provided with vomerine teeth, several specimens in our col- 

 lection, which, perhaps, are the Cystignathus Georgianus of D. & B., 

 and which can scarcely be generically separated from our Ptero- 

 phryni, have those teeth well developed. Tschudi has proposed the 

 name of Crinia for the last-named species. 



Pterophrynus tasmaniensis. 



Very similar to Camariolius pictus, Peters ; upper and lower parts 

 nearly entirely smooth, with scarcely any trace of flat tubercles. Snout 

 rounded in front, somewhat pointed, sloping downwards in a gentle 

 curve from the nostrils. Eye of moderate size, rather longer than 

 its distance from the nostril. Tongue narrow, ovate, entire behind ; 

 vomerine teeth none. Toes fringed ; tarsus without longitudinal 

 fold \ metatarsus with two minute tubercles. The length of the 

 body equals the distance between vent and metatarsal tubercles. 

 Upper parts blackish brown, with a more or less distinct broad red- 

 dish-olive band running from behind the eye towards the loin ; lower 

 parts beautifidly rose-coloured, largely marbled with black ; the pre- 

 anal parts black.
