irregular dark spots on dorsolateral region and upper part of sides; a 

 narrow sepia band between the eyes extending to tips of "horns"; 

 muzzle in front of this band drab-gray with a darker canthal stripe 

 descending to edge of mouth; side of head drab-gray with two or 

 three irregular drab spots crossing it diagonally and a few small black 

 spots surrounding small tubercles near edge of lip; limbs drab to drab- 

 gray with two very wide seal brown to clove brown crossbancls; venter 

 pale Naples yellow, immaculate except for some small drab spots on 

 lower limb surfaces and a clove brown suffusion over the throat of 

 the male; anterior femur pale olive-buff, the gland Naples yellow; 

 posterior femur pale crab-gray with fine sepia marblings; palms of 

 hands and soles of feet slate gray, the tubercles and tips dull olive-buff. 



Remarks. — Frogs of cannibalistic habit are seldom plentiful, but it 

 is hoped that others of this species may be found in Colombia so that 

 some estimate of variation may be possible. The example just described 

 has been compared with USNM 127141 from Puerto Santa Clara, 

 Orellana, Peru, and the two were found to be practically identical in 

 structure, proportions, and color pattern, except that the latter, being 

 a female, had a pale olive-gray throat. 



This species is closely related to Ceratophrys varia Wied (=dorsata 

 Tschudi) found in Brazil. Although Nieden's key separates these two 

 species on the basis of a bony shield in the center of the back, present 

 in varia but supposedly absent in cornuta, the shield is present in both 

 forms. In varia, however, vomerine teeth are present although small; 

 in cornuta they are lacking. The toes of varia are webbed only at the 

 base, while those of cornuta are about one-half webbed. The color 

 patterns are much the same, however. 



A young specimen (MLS 52) from Villa Maria, Caldas, has the 

 following measurements in millimeters: head and body, 27; head 

 length, 12.5; head width, 16.5; femur, 10; tibia, 10; foot, 10.5; hand, 8.5.
