FROGS OF COLOMBIA — COCHRAN AND GOIN 151 



Manso, Cordoba, collected by Fred Medem, adds to our knowledge 

 of variation in this rare species. Two breeding females in the series 

 have head and body lengths of 62.4 and 66.3 mm., while the males 

 range from 47.2 to 51.2 mm. in head and body length. Both females 

 and three of the males have the gaudy, rounded, black-bordered white 

 spots on the back as do those in the type series; and all the males 

 exhibit the brown patch on the inner side of the thumb, but this patch 

 is missing in both females. 



Remarks. — Boulenger (1913, pp. 1024, 1025) described and illus- 

 trated amplexus and the breeding process in this species. The leaf, 

 with the eggs attached, is still present with the type series.

Diagnosis. — A Cerathyla with a long fleshy proboscis and elon-

This species may be distinguished from C. johnsoni, the other 

 Colombian species of the genus, by having the proboscis and super-
