a. Bad state. Port Essington. From Mr. Gilbert's Collection. 

 This species is very probably the type of a separate genus ; but 

 the condition of the single specimen does not enable me to give 

 the characters with cei-tuinty. 



10. LEPTOPELIS*. 



Vomerine teeth. Skin of back smooth. Disks rather large ; fin- 

 gers sUghtly webbed, toes broadly webbed. Tympanum distinct ; 

 eustachian tubes moderate ; tongue heart-shaped, slightly nicked 

 behind. Male with an external subgular sac. Africa. 



Hyla, sp., Hallowell, A. Dumeril. 



The species, for which I establish the above genus, was considered 

 to be a species of Hyla, having the same external characters. But as 

 this genus is represented in the -Ethiopian region by Hyperolius, I 

 was induced to make a closer examination, by wliich the difference 

 in the structure of the diapophysis of the sacral vertebra was ascer- 

 tained. From Polypedates it difiers in the shape of the tongue.
