KUNGL. SV. VET. AKADEMIENS HANDLINGAR. BAND 52. N:o 9. 13 
In a paper on Batrachians in Results of Dr. E. Mjöbergs Swedish scientific Ex- 
peditions to Australia (K. Sv. Vet. Ak. Handl., Bd. 52, N:o 4) I have expressed my doubts 
regarding the correctness of the specifical distinction of Ps. bibronii GUNTHER and 
Ps. australis GRAY, doubts already expressed by BoULENGER in his catalogue, though 
the correctness of these has not been admitted by the Australian authors. By the 
great kindness of Mr J. J. FLETCHER I have received a typical specimen of Ps. 
australis, which I compared with specimens of Ps. bibronii from different localities. 
This comparison has not convinced myself, that I was mistaken; on the contrary it 
has confirmed me in my opinion, as I am not able to find any differences between 
the two »species», except some slight ones with regard to the colour. Generally the 
colour varies in a high degree in most species of batrachians and can not be used 
as the chief difference between two species, especially when the differences are so 
small as in the two forms in question. The streak along the coccyx is very distinct 
in the specimen received as Ps. australis, but it may be found in Ps. bibromii as 
well (see my figure 3 in the paper quoted). A distinct white spot is to be seen 
both on the anterior and posterior sides of the thighs in Ps. australis as well as in 
the specimen of Ps. bibronti, just mentioned. The spot on the humerus is also of 
the same shape in both specimens. The light colour of the head is the only diffe- 
rence I can find between this typical specimen of Ps. australis and the specimen of 
Ps. bibronir, figured by me, but, as my figure 4 (in the paper quoted) shows, even 
this colour-pattern does not belong to Ps. australis alone, which is said to live only 
in the surroundings of Sidney. 
As GRAY's name is the older, this species ought, according to my opinion, to 
be named Pseudophryne australis with forma bibronii as the most common colour- 
variety.

One specimen from Colosseum, Southern Queensland; November 1912. 
My astonishment was great, when I found in these collections from Queensland 
a specimen of the genus Pseudophryne, which much resembles the two specimens 
from Noonkambah in the interior of N. W. Australia, which Dr. MJÖBERG brought 
home from his first Australian expedition, and which I have described as Ps. mjö- 
bergit in Results of this expedition; (K. Vet. Akad. Handl., Band 52, N:o 4, p. 19). 
In fact the resemblance is so great that I have hesitated, whether I should describe 
it as a variety of Ps. mjöbergi. 
Snout subacuminate, shorter than the orbital diameter; nostril much nearer the 
tip of the snout than the eye; interorbital space broader than the upper eyelid. 
Tongue oval, entire, and free behind; no vomerine teeth. Fingers free, rather short,
