The claw-shaped terminal phalanges constitute a character which 
distinguishes this genus at once from any other of the family Ranide. 
This character and the vertical pupil separate it from Polypedates, 
to which it bears some resemblance. 
In Mr. Cope’s classification this genus is split into two, viz. Hylam- 
bates and Leptopelis, falling into two different groups of the family 
Ranide. Leptopelis is said to differ from Hylambates in the claw- 
shaped distal phalanges. Upon what species the former is founded 
is not stated; but I suppose it is intended for Hyla aubryi. I 
have not been able to recognize the difference pointed out by Mr. 
Cope, all the species I haye examined (4. aubryi as well as H. mar- 
moratus) haying the distal phalanges as in the genus Hyla.
