FROGS OF COLOMBIA — COCHRAN AND GOIN 413 



Remarks. — While the 15 frogs examined do not give a complete 

 picture of the variability of E. sanctae-martae, the six critical propor- 

 tions fall within the same range of significance as those of E. erythro- 

 pleurus, to which it is allied in other characters, such as the granular 

 belly, finely granular back, the presence of a heel tubercle (or at least 

 a ridge across the heel), and in having the adpressed heel reach between 

 the center of the eye and the tip of the snout. It differs from erythro- 

 pleurus in having much larger finger disks and a smaller tympanum 

 that is situated at a greater distance from the eye. 



The toes are definitly webbed at the base in all but one of the 

 specimens examined, and that one has a mere trace of a web. Usually 

 the belly is coarsely granular, but it is nearly smooth in one example. 

 In some frogs the glandular W behind the head is more distinct in 

 outline and color than in the one described. Two of the frogs show 

 continuous dark lateral stripes below the dorsolateral folds, and in 

 these the center of the back is paler.

Description. — ZIMUG 67/ — (the designated lectotype), an adult 

 collected on the road between La Uni6n and Chingasa, at 1,000- 

 2,400 meters, in Cundinamarca, Colombia. No bony ridges on top of 

 head. A large shield-shaped frontoparietal depression. Vomerine teeth 

 in two small, narrowly separated, slanting series behind the choanae; 

 tongue broad, two-thirds as wide as mouth opening, cordiform, its 

 posterior border free and deeply notched; snout moderately long, 

 rounded when viewed from above and in profile, the upper jaw 

 extending well beyond the lower. Nostrils dorsolateral, scarcely pro- 

 jecting, their distance from end of snout two-thirds their distance 

 from eye. Can thus rostralis sharp; loreal region flat, flaring outwards 

 to the upper lip. Eye large, prominent, its diameter a little less than 

 its distance from tip of snout; interorbital diameter nearly twice that 

 of upper eyelid, equal to interval between nostrils. Tympanum dis- 

 tinct, its greatest diameter not quite one-half that of eye, separated
