somewhat similar crossbands are on the dorsal surfaces of the shanks 

 and arms. The specimen is rather dark below. 



Remarks. — At first glance, the thigh pattern of this species makes 

 one think of Hyla boulengeri; in fact, this species has a more Hyla-\ike 

 mien than has either C. boulengeri or C. fuhrmanni. 



The vomerine teeth and the more or less cylindrical sacral di- 

 apophyses convinced us that this new species should be described as a 

 Cryptobatrachus. The life history is completely unknown. 



The holotype, which is in the collection of the Museo del Instituto 

 de La Salle, may well be the same specimen on which Dunn (1943, 

 p. 311) based his statement that there was an undescribed species of 

 Cryptobatrachus in northern Colombia. 



The holotype was the only specimen examined.

Diagnosis. — A Cryptobatrachus with thick thighs that are rather 

 dark posteriorly. 



This species may be distinguished from C. nicefori by the lack of 

 distinct dark crossbands on the thighs and distinct light spots on the 

 back. From C. boulengeri it may be distinguished by its having a 

 rougher, wartier skin, generally darker color both above and below, 

 more distinct folds along the dorsolateral region, and the distance 

 from the anterior corner of the eyelid to the naris distinctly less than 

 the distance between the anterior and posterior corners of the eyelids. 



Description. — MCZ 11616 (type of incertus) from Sons6n, Antioquia, 

 Colombia. Vomerine teeth in two short, heavy, transverse series lying 

 close together (but with a distinct gap) on a level with the posterior 

 borders of the choanae; tongue narrow, about half as wide as mouth 

 opening, its posterior border fused and without a distinct notch. Snout 

 moderate, broadly ovate when viewed from above, slightly projecting 

 when viewed in profile, the upper jaw extending slightly beyond lower; 

 no s trils more lateral than superior, very slightly projecting, their dis- 

 tance from end of snout about one-half that from eye, separated from 

 each other by an interval about equal to their distance from eye. 

 Can thus rostralis well denned; loreal region concave and somewhat 

 oblique; the upper lip flaring out slightly below it. Eye moderate,
