FROGS OF COLOMBIA — COCHRAN AND GOIN 



267 



Diagnosis. — A small Hyla with reduced webbing between the fingers, 

 small, rounded patches of vomerine teeth, and with a large, oval light 

 spot on the anterior face of the thigh that is surrounded by an ocellus- 

 like dark band. 



H. bokermanni is perhaps most closely allied to H. parviceps, from 

 winch it differs in being of smaller size and in having shorter legs and 

 a different pattern. 



Description. — CJG 2355, from Rio Manso, Cordoba, Colombia. 

 Vomerine teeth in two small, rounded series, lying on a level with the 

 posterior halves of the small, rounded choanae; tongue three-fourths 

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

 slightly free and shallowly notched. Snout short, rounded when 

 viewed from above, truncate in profile, the upper jaw barely ex- 

 tending beyond lower; nostrils more lateral than superior, consider- 

 ably projecting, their distance from end of snout about one-half that 

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

 three-fourths their distance from eye. Canthus rostralis moderately 

 defined; loreal region concave and nearly vertical, the upper lip not 

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

 nent, its diameter slightly greater than its distance from nostril; 

 palpebral membrane not reticulate; interorbital distance nearly twice 

 the width of upper eyelid, which is about equal the distance between
