ing from the occiput to near the termination of the body, and upon 

 the head, from one eye to the other, a V-shaped patch, the summit of 

 which is directed posteriorly. The inferior surface is of a uniform dull- 

 yellow. 



In the young, the ground color is light-green, with a few black spots 

 on the sides of the abdomen, exhibiting also the facial vitta, though 

 less distinctly. Inferiorly it is of a soiled white. 



Specimens were collected on Puget's Sound ; the colored drawings 

 were made from life by Mr. Drayton.

2. Hyla cyanea, Schleg. 



Syn. — Hyla cyanea, ScHLEG. Abbild. Amph. 1837-44, 26. PI. ix, fig. 2. 



Observ. — The only specimen of this species brought home from 

 Australia, by the Exploring Expedition, is a dried skin, so much 

 deformed in its prepared state, that we were unable to draw up any 

 accurate description. 



The synonyms of this species, as quoted by Messrs. Dumeril and 

 Bibron (Erp. g^n. VIII, 1841, 577), are all referable, except Schlegel's, 

 to Ranoidea aurea {Hyla jaclcsoniensis, DuM. & B.). 



But Schlegel is not the originator of either the species or the 

 specific name. He took the name from Fitzinger, who borrowed it 

 from Daudin, and applied it to a distinct and well marked species ; 

 whilst Daudin's Hyla cyanea is nothing else but his Rana coerulea, 

 which is identical with Ranoidea aurea.
