FROGS OF COLOMBIA — COCHRAN AND GOIN 391 



Colombian states bordering Peru, its type locality. In the Meta frog, 

 as well as in the five Peruvian examples (including two paratypes of 

 E. lymani), the adpressed heel reaches beyond the snout, either slightly 

 or considerably. The toes are distinctly webbed at the base. The venter 

 may be finely granular to nearly smooth but with a wrinkled appear- 

 ance. There are no pronounced heel tubercles, but most examples 

 have one or two small ridges crossing the heel.

Description. — BM 1910.7.11.63, an adult male from Rio San Juan, 

 Choc6, Colombia. Vomerine teeth in two small, slanting, nearly 

 contiguous series behind the choanae; tongue a little over one-half 

 the width of mouth opening, cordiform, its posterior border free and 

 notched; snout moderately long, rounded when viewed from above, 

 broadly rounded in profile, the upper jaw extending slightly beyond 

 the lower. Nostrils lateral, projecting, their distance from end of snout 

 about one-third their distance from eye. Canthus rostralis distinct, 

 straight; loreal region concave, slanting outwards to the upper lip. 

 Eye large, prominent, its diameter equal to its distance from tip of 

 snout; a small conical tubercle on upper eyelid; interorbital diameter 

 about iy 2 times that of upper eyelid and slightly greater than interval 

 between nostrils. Tympanum small but distinct, its greatest diameter 

 approximately one-fourth that of eye, separated from eye by an 

 interval equal to one-half its own diameter. Fingers long, slender, 

 with lateral ridges, free, first finger shorter than second, fourth longer 

 than either and reaching nearly to base of disk of third, which covers 

 three-fourths the tympanum, an oval thumb pad present; a partly 

 divided palmar callus; metacarpal tubercles well developed. Toes 

 long, the first and second with a slight web, the others unwebbed, 

 third toe shorter than fifth, the disk of which reaches midway on 

 antepenultimate phalanx of fourth; disk of fourth toe covering about 

 three-fourths the tympanum and equal to that of third finger; a 

 small but distinct semilunar inner metatarsal tubercle and a smaller 

 round outer one; a tarsal ridge, ending halfway to knee; a conicle 

 tubercle on heel and a skinfold on heel and knee. Body slender, in
