FROGS OF COLOMBIA — COCHRAN AND GOIN 411 



hands cream buff, the disks pale sepia; side of head ochraceous-buff, 

 with an indistinct sepia marbling on upper lip and a wider sepia stripe 

 below canthus. 



Remarks. — In all but one of the 18 specimens at hand, the adpressed 

 heel reaches a point between the posterior border of the eye and the 

 shoulder; in the exception the heel reaches the center of the eye. The 

 toes in all examples are plainly webbed at the base. A slight heel 

 appendage may be discerned in some, but most have only a few blunt 

 tubercles or rugosities on the heel. While some of the frogs are very 

 dark, so that the pattern is not distinct, others are paler brown, with 

 the elaborate dark marblings very apparent. The venter is heavily 

 spotted with brown in most individuals, but in a few the spotting is 

 much reduced, or confined to the posterior part of the body. The 

 wide toad-like head and the swollen parotoid region allow one to 

 recognize the species fairly easily.

Description. — MZUM 54541, an adult male from San Lorenzo, 

 Magdalena, Colombia. No bony ridges on top of head; frontoparietal 

 area depressed. Vomerine teeth in two transverse, short, narrowly 

 separated series behind the choanae; tongue large, three-fourths as 

 wide as mouth opening, squarish, its posterior border free and very 

 slightly indented; snout fairly long, ovate when viewed from above, 

 rounded in profile, the upper jaw extending well beyond the lower, 

 which is truncate in front. Nostrils dorsolateral, projecting, their 

 distance from end of snout about one-third their distance from eye. 

 Canthus rostralis strong; loreal region flat, the upper lip flaring out 

 below it. Eye large, prominent, its diameter about five-sixths its 

 distance from tip of snout; interorbital diameter equal to that of 

 upper eyelid and also to interval between nostrils. Tympanum small 

 but very distinct, its greatest diameter about two-fifths that of eye,
