FROGS OF COLOMBIA — COCHRAN AND GOIN 25 



Five examples (USNM 146834-8, collected by Hno. Nic&oro 

 Maria) from Sutatenza, Antioquia, are quite similar to those men- 

 tioned above but differ from them in being much lighter in color. 

 No maxillary teeth can be found; otherwise, they might be grouped 

 with one of the smaller kinds of Phyllobates.

Description. — USNM 144980, an adult from La Ceja, Monte del 

 Diablo, Antioquia, Colombia. Tongue almost half as wide as mouth 

 opening, oval, its posterior border free and unnotched; snout broadly 

 rounded when viewed from above, truncate and slanting backwards 

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

 lateral, slightly projecting, their distance from end of snout being 

 half their distance from eye. Can thus rostralis bluntly rounded; 

 loreal region flat, vertical, continuous with the upper lip. Eye large, 

 prominent, its diameter about 1% times its distance from tip of snout; 

 interorbital diameter a little greater that that of upper eyelid, equal 

 to interval between nostrils. Tympanum distinct, its greatest diameter 

 about one-third that of eye, separated from eye by an interval equal 

 to one-quarter its own diameter. Fingers moderate in length, with 

 faint lateral ridges, free, first finger much shorter than second, fourth 

 a little longer than second, its tip reaching to base of penultimate 

 phalanx of third, the disk of which covers about three-quarters the 

 tympanum; all the finger disks relatively large; an indistinct thumb 

 pad present; a round palmar callus; metacarpal tubercles well 

 developed. Toes moderate, with traces of a web between the three 

 outer ones, third toe longer than fifth, its disk reaching to center of 

 antepenultimate phalanx of fourth; disk of fourth toe covering 

 two- thirds the tympanum and smaller than that of third finger; an 

 indistinct inner metatarsal tubercle and a poorly defined outer one; 

 no true tarsal ridge, but a short diagonal gland crossing tarsus mid- 

 way to heel; a distinct skinfold on heel and knee. Body moderately 

 elongate, in postaxillary region a little narrower than greatest width 

 of head. When hind leg is adpressed, heel reaches to posterior corner
