Diagnosis. — A rather large Hyla of the rubra group with broad, 

 vertical dark bars on the posterior faces of thighs and generally with 

 a rather light chin and throat. 



From its close relatives in Colombia H. boulengeri may be distin- 

 guished from H. rubra by having the dark markings on the posterior 

 surfaces of the thighs in the form of broad, vertical dark bands rather 

 than in the form of vermiculations; and from H. joliamorta by having 

 the undersurface of the proboscis, the chin, and the throat pale rather 

 than dark. For a detailed comparison of boulengeri with joliamorta see 

 "Remarks" under the latter species. 



Description. — CNHM 81854, from Andagoya, Choco, Colombia. 

 Vomerine teeth in two transverse series, lying close together between 

 the moderate-sized, very elongate choanae; tongue two-thirds as 

 wide as mouth opening, broadly rounded, its posterior border fused 

 and with just a trace of a notch. Snout elongate, rather lanciform 

 when viewed from above, rounded in profile, the upper jaw extending 

 somewhat beyond lower; nostrils more lateral than superior, con- 

 siderably projecting, their distance from end of snout about one-fourth 

 that from eye, separated from each other by an interval equal to 

 about two-fifths their distance from eye. Canthus rostralis slightly 

 defined; loreal region concave and rather oblique, the upper lip 

 flaring out strongly below it. Eye moderate, not particularly promi- 

 nent, its diameter equal to about three-fifths its distance from nostril; 

 palpebral membrane not reticulate; interorbital distance slightly 

 greater than width of upper eyelid, which is in turn equal to the 

 distance between nostrils. Tympanum very distinct, about three-fifths 

 the diameter of eye, separated from eye by a distance equal to one-
