Diagnosis. — A small Hyla of the variabilis group with reduced 

 webbing between the fingers, a pale patagium, and generally with 

 a pair of fairly well developed darker stripes down the back. 



This new species is most closely allied to variabilis and columbiana. 

 From the former it can be distinguished by having a shorter hind 

 leg (heel reaching posterior margin rather than anterior margin of 

 e y e )> by having the pattern generally of two fairly distinct dark 

 stripes on the back instead of broken lines and blotches, and by 

 having less mottling below. From columbiana it differs in its shorter 

 leg and in having a distinct dorsal pattern. 



Description of holotype. — Vomerine teeth in two small, rounded 

 patches, lying close together between the small, rounded choanae; 

 tongue two-thirds as wide as mouth opening, broadly rounded, its 

 posterior border slightly free and unnotched. Snout short, somewhat 

 rounded when viewed from above, nearly truncate in profile, the 

 upper jaw not extending appreciably beyond lower; nostrils more 

 lateral than superior, hardly projecting, their distance from end of 

 snout about one-half that from eye, separated from each other by 

 an interval nearly equal to their distance from eye. Canthus rostralis 

 moderately well defined; loreal region slightly concave and slightly 

 oblique, the upper lip flaring out a little below it. Eye small, not 

 prominent, its diameter equal to its distance from nostril; palpebral
