Pupil erect. Tongue free and more or less deeply notched behind. 

 Vomerine teeth. Tympanum distinct. Fingers free or webbed ; 

 toes more or less webbed, the tips dilated. Outer metatarsals 

 united. Omosternum and sternum with a bony style. Terminal 

 phalanges claw-like, swollen at the base. 



Tropical Africa. 



The claw-shaped terminal phalanges constitute a character which 

 distinguishes this genus at once from any other of the family JRanidce. 

 This character and the vertical pupil separate it from Pulypedates, 

 to which it bears some resemblance. 



In Mr. Cope's classification this genus is split into two, viz. Ht/lam- 

 bates and Leptopelis, falling into two different groups of the family 

 Ranidc. LeptopeJis is said to differ from Htilamhates in the claw- 

 shaped distal phalanges. Upon what species the former is founded 

 is not stated ; but I suppose it is intended for Hyla aubn/L I 

 have not been able to recognize the difference pointed out by Mr. 

 Cope, all the species I have examined (II. aubryi as well as //. mar- 

 moratus) having the distal phalanges as in the genus Hyla.
