color, which is dirty yellow with darker mottlings. There is a distinct, 

 pale, transverse line above the vent, separating dorsal yellow from 

 gray color of posterior thighs. There are two bright yellow spots 

 below the vent, but these are not definite warts as they are in the 

 Colombian specimen. 



The described specimen also was compared directly with the type 

 of angustifrons. It is somewhat similar to that species in color, but 

 angustifrons lacks the superciliary processes and really seems to be 

 quite distinct. It may well be that after more information becomes 

 available on cornutum our specimen will be found to represent a 

 distinct species; until then, maneat!

 Dunn, 1944b, p. 405.— J. Peters, 1952, p. 15.— Gorham, 1963, p. 21. 



Diagnosis. — A large Gastrotheca with the derm of the head co- 

 ossified with the roof of the skull and with the intersquamosal shelf 

 complete and forming a nearly straight transverse margin at the 

 back of the head. It lacks superciliary processes and dermal heel 

 appendages. 



This species can be immediately distinguished from all Colombian 

 Gastrotheca except medemi by having the cranial derm fused to the 

 skull and by having the straight posterior margin to the intersqua- 

 mosal shelf. From medemi it can be distiguished by its broader head 

 and its longer leg (tibia greater than half the distance from snout to 

 tip of urostyle). 



Description. — MZUM 73242 (holotype), from Pensilvania, Caldas, 

 Colombia. Vomerine teeth in two short, rather heavy, transverse 

 series lying close together between the small, rounded choanae; 

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

 posterior border slightly free and shallowly but distinctly notched. 

 Snout moderate, somewhat U-shaped when viewed from above, 

 sloping in profile, the upper jaw not extending considerably beyond 

 lower; nostrils more lateral than superior, not projecting, their dis- 

 tance 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 sharply defined; loreal region slightly
