FROGS OF COLOMBIA — COCHRAN AND GOIN 215 



fully, it is plain to see that the same basic pattern obtains. Where the cotypes are 

 pale yellow, the CNHM specimen is pale to medium brown, and where the cotypes 

 are brown the Chicago Natural History Museum specimen is nearly black; 

 however, the latter apparently was preserved in too strong formalin, while the 

 cotypes look as though they didn't have quite enough.

Figure 20; Plate 29a-c 



Holotype. — USNM 152759, collected along the Catio Guacaya, a 

 tributary of the lower Rio Apaporis, Amazonas, Colombia, by I. 

 Cabrera in May 1952. 



Paratypes. — CJG 2317, collected along the Cano Tui between Mitu 

 and the Raudal de Yurupari, Vaupes, October 17, 1951 by I. Cabrera, 

 and WCAB 13284, from Amapa Territory, Brazil. 



Diagnosis. — A moderate-sized Hyla with a patagium, a distinct 

 pattern on the back, throat and chest heavily sprinkled with small but 

 distinct dark brown spots, and the fingers about one-half webbed. 



H. cabrerai is most closely allied to H. buckleyi, from which it differs 

 in having chest and throat spotted and a greater amount of webbing 

 between the fingers. 



Description oj holotype. — Vomerine teeth in two moderate, slightly 

 arched series, lying between the moderate-sized, oblong choanae; 

 tongue three-fourths as wide as mouth opening, broadly ovate, its 

 posterior border but slightly free and unnotched. Snout moderate, 

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

 extending but slightly beyond lower; nostrils more lateral than supe- 

 rior, considerably projecting, their distance from end of snout about 

 one-third that from eye, separated from each other by an interval 

 equal to about two-thirds their distance from eye. Canthus rostralis 

 well defined ; loreal region concave and oblique, the upper lip flaring 

 out below it. Eye moderate, not particularly prominent, its diameter 

 nearly equal to its distance from nostril; palpebral membrane not 

 reticulate; interorbital distance slightly greater than width of upper 

 eyelid, which is relatively wide and slightly greater than distance 

 between nostrils. Tympanum very distinct, about three-fourths the 

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

 half its own diameter. Fingers one-half webbed, fourth finger consider-
