olive green or uniformly of the purest of pea-greens. The 

 brown bands and spots do not change to any great extent 

 when put into alcohol, but the green almost entirely 

 disappears. The under-surfaces are lemon yellow. The 

 resemblance of this frog to Hyla regilla, Bd. and Gir., of 

 North America, as regards its life colours, is worthy of note. 

 H. regilla has been beautifully figured by Miss Mary C. 

 Dickerson,* two plates showing clearly the enormous 

 range of colour and marking displayed by different 

 individuals, many phases of which forcibly suggest those 

 of H. ewingii v. alpina. 



Length of head, to hinder edge of tympana 12 mm. 



Width of head at tympana .. .. 17 mm. 



Total length, snout to anus . . . . . . 48 mm. 



Length of hind- limb to tib. -tars. art. .. 41 mm. 



Locs. : — Twenty-two specimens from Mount Kosciusko, 

 Monaro District, Southern tableland. New South Wales. 

 Three specimens collected by Mr. A. R. McCulloch were 

 taken at an altitude of 5,200 feet. Mr. Charles Hedley 

 and Mr, Robert Helms have taken them at 5,500 feet, 

 while four collected by Dr. T. H. Johnston are said to be 

 from 7,000 feet altitude. I have to thank Messrs. Hedley, 

 Johnston, and McCulloch for their kindness in bringing 

 me specimens alive. 



This new variety can be distinguished from the other 

 varieties of Hyla ewingii, D. and B., by its warty back, 

 scarcity of webbing, small discs and tapering fingers, and 

 by the predominance of green in its life colouration. As 

 regards the amount of webbing and size of the finger discs, 

 however, var. alpina overlaps some examples which are 

 true specimens of var. orientalis.

Mr. J. J. Fletcherf has gone very fully into the relative 

 values and distribution of the proposed varieties of H. 

 ewingii. As the result of a careful examination of over 

 one hundred specimens, he arranges the varieties as follows :
