Description. — CNHM 54789, from Pueblorrico, Caldas, Colombia. 

 Vomerine teeth in two heavy / \ series, lying close together between 

 the large, oblong choanae; tongue three-fourths as wide as mouth, 

 opening, broadly cordiform, its posterior border very slightly free 

 and very shallowly notched. Snout large, broadly triangular when 

 viewed from above, rounded in profile, the upper jaw extending a 

 little beyond lower; nostrils more lateral than superior, slightly 

 projecting, their distance from end of snout about one-fourth that 

 from eye, separated from each other by an interval equal to about 

 one-half their distance from eye. Can thus rostralis well defined; 

 loreal region concave and very oblique, the upper lip flaring out 

 strongly below it. Eye moderate, fairly prominent, its diameter not 

 quite as great as its distance from nostril; palpebral membrane 

 reticulate; interorbital distance half again as great as width of upper 

 eyelid, which is relatively wide and slightly greater than distance 

 between nostrils. Tympanum very distinct, about one-half the diameter 

 of eye, separated from eye by a distance nearly equal to one-half its 

 own diameter. Fingers webbed, the web on third finger reaching base 

 of disk on lateral side and middle of penultimate phalanx on medial 

 side, fourth finger longer than second, reaching to middle of disk of 

 third which more than covers the tympanic area; rudiment of a pollex 

 not pronounced; a low ulnar ridge. Toes completely webbed, the web 

 on fourth toe reaching the base of the disk; third and fifth toes sub- 

 equal, disk of fourth toe slightly larger than the tympanic area; a 

 distinct oval inner but no apparent rounded outer metatarsal tubercle; 

 a very indistinct tarsal ridge; a short broad triangular dermal append- 

 age on heel. Body elongate, in postaxillary region but little narrower 

 than greatest width of head; when hind leg is adpressed, heel reaches 

 beyond tip of snout; when limbs are laid along the side, knee and 

 elbow overlap; when hind legs are bent at right angles to body, heels 

 overlap slightly. No patagium. Skin of upper parts smooth; a low 

 indistinct glandular ridge encircling upper part of tympanum, skin 

 of throat and chest smooth, that of belly and lower surface of thigh 

 uniformly granular; no traces of a skinfold across chest; adult female, 

 no vocal sac. Skin of head not co-ossified with skull, roof of skull not 

 exostosed. 



Dimensions. — Head and body, 90 mm.; head length, 30.6 mm.; 

 head width, 32.1 mm.; femur, 47.2 mm.; tibia, 49.3 mm.; heel-to-toe, 

 63.8 mm.; hand, 27.3 mm. 



Color in alcohol. — Pale brown above, dirty tannish gray below. The 

 dorsal pattern consists of a narrow median stripe that extends from 

 tip of snout to about the sacral hump, where it fades out. Some dozen 

 small brownish spots, a few millimeters in diameter, are scattered 

 over the back, with most of them clustered in middle of the back
