web. The rather distinct folds along the free distal joints, I think, have caused 
that the web has been recorded too large. Indeed, in some of the small specimens 
the foot seems to be not even halfwebbed. 
Hyla ewingii. Dum. & BIiIBR. — One specimen from Adelaide, ''"/10 1911. 3, 
23 mm. EE. Mjöberg. 
The type specimen of this species was obtained from Tasmania where this spe- 
cies according to ENGLISH (Proc. Zool. Soc. 1910 p. 632) is common; it is also fre- 
quently found in the coastal division of N. S. Wales (FLETCHER), as well as in Vic- 
toria (FLETCHER, LUCAS), and it seems to live in the whole southern coastal division, 
being recorded from King George's Sound as well as from Adelaide. GÖNTHER (Ann. 
Nat. Hist. 1867) has obtained it from North-East Australia, and very probably KREFFT 
is right in saying that this species lives in »almost every part of Australia the west 
coast excepted» (quoted from FLETCHER 1892, p. 14). Probably, the interior districts 
of the continent may also be excepted, although FLETCHER sometimes has found it 
in New South Wales west of the Dividing Range (FLETCHER 1892, p. 7, 8, 13—16), 
»probably a straggler from the coast>. 
Hyla calliscelis, described by PETER's 1874 in Monatsber. Berl. Ac. p. 620, is 
now considered as a mere variety of H. ewingii, differing from the typical form by 
purplish black spots on thighs and in the groin. PETER's type-specimen was from 
Adelaide, and according to FLETCHER Hyla ewingir is represented in New South Wales 
only by this variety, which also has been recorded from St. George's Sound, whereas 
the typical form lives in Victoria and Tasmania. The spotted variety has extended 
from there to the North as well as to the West. Thus, as my specimen is collected 
at Adelaide, it ought to be referred to var. calliscelis as well, and in fact there are 
to be found in the groin a dark, although rather indistincet patch as well as some 
rather large purplish-black spots on the hind side of the thighs. These markings 
are absent in a specimen from Victoria, kept in the R. Museum of Nat. History, 
and if really these two forms should be maintained as different varieties, the pre- 
sent specimen may be considered as a calliscelis. Yet, the differences between the 
specimen from Adelaide and the typical specimen from Victoria, examined by me, 
are very unimportant, the lumbar spot especially being rather indistinct. Besides, I 
may add to this that in the N. S. Wales specimens of var. calliscelis, according to 
FLETCHER, the spots frequently are lacking on the hind surface of the thighs. 
Hyla adelaidensis. Gray — Fig. 9, 10. — 5 specimens, Perth, Freemantle, 
Aug.—Sept. 1910; 3 males 45—57 mm., 2 females 70—72 mm. E. Mjöberg. 
GRAY”s type specimens are also collected in the coastal division of West Aust- 
ralia, although there is no account of the exact locality. In GÖNTHER'S catalogue 
1858 this species is recorded from Port Essington, N. Australia; PETERS states it 
(1863) from Adelaide and GÖNTHER 1867 from Port Denison (Queensland). If Hyla
