FROGS OF COLOMBIA COCHRAN AND GOIN 437 



niiddorsal stripes. All have a narrow dark stripe from tip of snout, 

 along can thus, and above tympanum, ending behind it; two large 

 dark spots from eye to lip, usually crossed by a narrow white line 

 paralleling the lip. Palms and soles mouse gray, the disks and tubercles 

 lighter. 



Remarks. — A characteristic found in megalops is the presence of a 

 tubercle (or sometimes of several small tubercles) on the heel, and 

 rarely with a ridge or swelling across it. The skin of the belly is granular 

 to faintly granular in 60 percent of the specimens examined and 

 smooth to pustular (under the lens) in the remainder. The back often 

 shows several short glandular ridges, while some of the larger frogs 

 have tubercles more or less thickly scattered on the back. 



While the toes were said to be free in the original description, in 

 several specimens at hand (including a paratype, USNM 64026 from 

 San Lorenzo) the toes are faintly webbed. The throat, chest, and 

 anterior half of belly are usually brown-spotted, the rest of the belly 

 being immaculate, in this respect agreeing with longirostris.

Plate 58a-c 



1965. Eleutherodactyhis lehmanvalenciae Thornton, p. 425, fig. 1 (type locality 

 approximately five miles upstream from mouth of Raposo River and 

 20 miles south of Buenaventura, Department of Valle, Colombia). 



Description. — USNM 151399 (holotype), an adult female collected 

 approximately five miles upstream from mouth of Rio Raposo and 

 20 miles south of Buenaventura, Valle, Colombia. No bony ridges on 

 top of head. Vomerine teeth in two small, slanting, nearly contiguous 

 series well back of the choanae; tongue one-half as wide as mouth 

 opening, broadly cordiform, its posterior border free and faintly 

 notched; snout broadly rounded when viewed from above, truncate 

 in profile, the upper jaw extending slightly beyond the lower. Nostrils 

 more lateral than dorsal, projecting, their distance from end of snout 

 barely one-fourth their distance from eye. Canthus rostralis distinct, 

 concave; loreal region nearly flat, sloping outwards to the upper lip. 

 Eye large, prominent, its diameter equal to its distance from nostril;
