FROGS OF COLOMBIA — COCHRAN AND GOIN 167 



Color in alcohol. — A gaudy frog with a bright pattern on a ground 

 color of tannish brown. Sides and top of head and loreal region with 

 scattered, distinct, rounded black dots. Larger, rounded, black spots 

 in a row along the margin of the upper jaw; margin of upper jaw be- 

 tween these spots nearly white. Transverse bands of dark brown cross 

 the dorsum from the back of the head to hind end of the body, these 

 dark bands being rather conspicuous on a ground color of light brown. 

 Dorsolateral folds nearly black but the tiny, triangular fleshy processes 

 they bear are nearly white. Distinct bands of dark pigment on a 

 lighter ground color cross the dorsal surfaces of the arms and hands 

 and the legs and feet. The margin of the lower lip is white but the chin 

 and underside of the throat are coal black. The chest and belly and 

 the underside of the arms and legs are yellowish and heavily mottled 

 with dark brown and black areas. 



Remarks. — This remarkably distinct species is known from the 

 single specimen collected by Hno. Niceforo Maria at Ventanas. 

 Superficially the holotype looks more like G. ceratophrys of Panama 

 than any other form, but it differs from that species in having dermal 

 appendages on the heels, in having the skin of the cranium co-ossified 

 with the skull, and in having well-developed dorsolateral folds that 

 bear tiny, triangular dermal appendages. 



This is another of the many new species of frogs from Colombia 

 for which our science is indebted to our good friend Hermano Niceforo 

 Maria. 



The specific name is from the Spanish "bufon," a jester or clown, 

 in reference to the frog's gaudy appearance.

1963. Gastrotheca cornutum. — Gorham, 1963, p. 21. 



Diagnosis. — A Gastrotheca with superciliary processes but with 

 dermal appendage on heel reduced or absent. The cranial derm is not 

 fused to the skull. 



This species differs from all Colombian Gastrotheca except bujona 

 in having well-developed triangular processes growing out of the upper 

 eyelids. It differs from bujona in the reduced dermal appendages on 

 the heels and in having the cranial derm free from the skull. 



Description. — CNHM 54718, from Rio San Joaquin, 1,500 meters, 

 Pacific side, Cauca, Colombia. Vomerine teeth in two small, oval 

 series lying close together between the small, rounded choanae; 

 tongue two-thirds as wide as mouth opening, broadly ovate, its
