Habit as in Camariolius varius, Peters, but with the snout longer 
and more pointed ; the canthus rostralis is rather distinct hetween 
eye and nostril, and is strongly deflexed in front. Upper parts 
smooth, the lower coarsely granulated. Eye rather large, not much 
shorter than the snout. Tongue narrow, ovate, entire behind ; vo- 
merine teeth none, but there is a short, scarcely perceptible osseous 
ridge in front of the orbital groove. Toes not fringed; tarsus with 
a longitudinal fold of the skin ; metatarsus with two minute tubercles. 
The length of the body is more than the distance between vent and 
metatarsal tubercles. Upper parts reddish olive, 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 specimen 
of Pterophrynus verrucosus, Liitken, 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 comparing 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 Camariolius 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. levis has them very distinctly dilated, and P. afinis 
and P. tasmaniensis are, in this respect, intermediate between these 
extreme forms. They form only one genus, which, perhaps, must 
be still further extended ; for, whilst none of the species mentioned
