Belongs to the gracilenta-chloris group, Though I 
have followed Boulenger’s example, as typified in his Hyla 
chloris, in describing this form as a species, I consider that 
all the requirements of the case would be amply met if the 
three were looked upon as varieties of a single species. Their 
close relationship may be seen at once by a reference to the 
following key :— 
Snout shorter than diameter of orbit; tympanum dis- 
tinct ; tibio-tarsal articulation reaching to tip of 
snout ; upper arm and throat yellow; belly white. 
1. (gracilenta) chloris. 
Snout as long as diameter of orbit; tympanum rather 
indistinct ; tibio-tarsal articulation reaching to between 
eye and tip of snout ; lower surface immaculate white. 
. 2. gracilenta (typica). 
Snout much longer than diameter of orbit ; tympanum dis- 
tinct ; tibio-tarsal articulation reaching well beyond tip of 
snout ; entire lower surfaces orange. 
ms 3. (gracilenta) luteiventris. 
While lately preparing a rough lst of the Queensland 
batrachians I discovered that two of the genera involved were 
masquerading under names to which they had no legal title. 
These are Chiroleptes and Cryptotis, both of Dr. Giinther. 
The former is preoccupied in Hemiptera by Kirby, 1831, 
and shouid be replaced by Phractops, Peters ; while the latter 
is similarly rendered unavailable through its use in Crus- 
tacea by Dana, 1852. I, therefore, propose as a substi- 
tute Adelotus.
