with large buff spots; posterior femur fawn color above to dull burnt 

 umber below; palms of hands and soles of feet wood brown, the 

 disks and lower surfaces of toes buff. 



Remarks. — Two rather dried-up specimens (USNM 137531, 144936) 

 tentatively have been identified with this species. In one (USNM 

 137531), the venter is black with some large white spots; in the other, 

 it is light with black spots. In each, the back has essentially the same 

 dark median chevron as in the type, and the sides of the body are 

 similarly dark. As in so many other species known from but a few 

 examples, more material is needed in order to gauge variability.

Description. — CNHM 69748 (holotype), a male from Caicedo, 

 Antioquia, Colombia. Head a little longer than broad; tongue very 

 elongate, narrow, about one-fourth as wide as mouth opening, its 

 posterior border free and unnotched; snout long, subacuminate when 

 viewed from above, slanting backwards in profile, the upper jaw 

 extending well beyond the lower. Nostrils lateral, distinctly projecting, 

 their distance from end of snout equal to their distance from eye. 

 Can thus rostralis sharp and straight; loreal region concave, vertical 

 above, and flaring slightly to the upper lip. Eye large, prominent, its 

 diameter a little greater than its distance from tip of snout; interorbitul 

 diameter lj^ times that of upper eyelid, a trifle greater than interval 

 between nostrils. Tympanum hidden. Fingers rather short, with 

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

 longer than either, reaching midway on penultimate phalanx of 

 third; disks bulbous but not enlarged; two or three small tubercles 

 taking the place of a thumb pad; a flat round palmar callus; only the 

 basal metacarpal tubercles well developed, others weak. Toes mod- 

 erately long, third, fourth, and fifth one-half webbed, inner ones 

 fully webbed; third toe much shorter than fifth, the tip of which 

 reaches to base of antepenultimate phalanx of fourth; fourth and 

 fifth toes considerably reduced in size; a weak, rounded inner meta- 

 tarsal tubercle and a slightly stronger round outer one; a sharp, thin 

 tarsal ridge, ending near heel; a distinct skinfold on heel and knee.
