14 GEOGRAPHICAL DISTRIBUTION OF AUSTRALIAN BATRACHIA, 



Mr. Krefft (P.Z.S. 1863, p. 389) includes H. ewingii among the 

 Batrachians occurring in the neighbourhood of Sydney, and says : 

 " This pretty little Hyla is rather a rare species, and I do not 

 think that I ever found more than six or eight specimens of it 

 gener-ally under stones during the cold season." In the same 

 paper he says of H. verreauxii : " A rather rare frog, which I 

 have occasionally taken from under the bark of the Tea-tree, and 

 from under rocks in moist localities ; never taken during the 

 summer. No specimens from other parts of Australia have as 

 }'et come under my notice." Tn his paper on " Australian "Verte- 

 brata, Recent and Fossil" (Industr. Prog. N.S.W. [1871], p. 747), 

 we have a slightly different version : for it is there stated of E. 

 ewingii that the Sydney " Museum is in possession of specimens 

 from almost every part of Australia, the west coast excepted," 

 while U. verreauxii is said to be "very common almost everywhere 

 on the eastern border." 



One of our commonest frogs in the County of Cumberland, 

 equally common also in the three adjacent counties, though I have 

 not seen it from any inland localities, until it occurred in two of 

 Mr. Froggatt's collections noted above, is a little Hyla, of which 

 Mr. Boulenger kindly named specimens for me as H. ewingii var. 

 caUiscelis, Peters. It is the little frog whose shrill twee, twee, twee, 

 repeated from half-a-dozen to a dozen times or more, may be heard 

 in damp weather even during the winter months, as I have pointed 

 out elsewhere. From its common occurrence Mr Krefft was no 

 doubt familiar with this frog ; but as Peters' description was 

 published only in 1874, Mr. Krefft could not have i-ef erred to it 

 under this name in the papers quoted above. 



E. de7itata. Kef erst., is a Sydney frog, and was described in 

 Ai'chiv fiir Naturge.sch., for 1868, but it is not mentioned in the 

 latest of Mr. Krefft's pa[)ers published in 1871. It seems to me 

 therefore very probable that when Mr. Krefft referred to E. 

 ewingii and E. verreauxii as species occurring in the neighbour- 

 hood of Sydney and elsewhere on the east coast, he meant to 

 denote the two frogs now known as E. evnngii var. caUiscelis, 

 Peters, and E. dentata, Keferst.
