 This species is veiy probably the tji)e of a separate genus ; but 

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

 the characters with certainty.

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

 gers shghtly webbed, toes broadly webbed. Tympanum distinct; 

 eustachian tubes moderate ; tongue heart-shaped, sHghtly nicked

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 which the difference 

 in the stnicture of the cLiapoi)hysis of the sacral vertebra was ascer- 

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