projecting, their distance from eDd of snout about one-third that from 

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

 thirds their distance from eye. Can thus rostralis fairly well defined; 

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

 fairly strongly below it. Eye not large but prominent, its diameter 

 equal to its distance from nostril; palpebral membrane not reticulate; 

 interorbital distance about twice the width of upper eyelid, which is in 

 turn about equal the distance between nostrils. Tympanum very dis- 

 tinct, about three-fifths the diameter of eye, separated from eye by a 

 distance equal to one-half its own diameter. Fingers webbed at base, 

 web on third finger extending to middle of the antepenultimate pha- 

 lanx, fourth finger appreciably longer than second, reaching to disk of 

 third which covers about two-thirds the tympanic area; no projecting 

 rudiment of a pollex; a well-developed ulnar ridge. Toes slightly more 

 than one-half webbed, the web on fourth toe reaching base of the 

 penultimate phalanx, third and fifth toes subequal, disk of fourth toe 

 covering about one-half the tympanic area; a distinct oval inner but 

 no distinct outer metatarsal tubercle; well-developed outer and inner 

 tarsal ridges; no dermal appendage on heel. Body not elongate, in 

 postaxillary region appreciably narrower than greatest width of head; 

 when hind leg is adpressed, heel reaches anterior margin of eye; when 

 limbs are laid along the side, knee and elbow overlap considerably; 

 when hind legs are bent at right angles to body, heels overlap greatly. 

 No patagium. Skin of upper parts highly glandular, the dorsal surfaces 

 of head, body, arms, hands, feet, and legs uniformly and fairly con- 

 spicuously granular. Texture of the dorsal skin is somewhat reminis- 

 cent of the flesh of a stony pear. A rather narrow glandular ridge en- 

 circling upper part of tympanum; skin of throat and chest smooth, 

 that of belly and lower surface of thigh uniformly and finely 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, 35.2 mm.; head length, 14 mm.; head 

 width, 13.5 mm.; femur, 16.6 mm. ; tibia, 18.1 mm.; heel-to-toe, 24.6 

 mm.; hand, 10.5 mm. 



Color in alcohol. — This individual is now a uniform pale grayish 

 brown above and below. There is no sign of any pattern or pigmenta- 

 tion and the only color is the black of the choroid coat of the eye. 

 The black eyes tend to show through the partially translucent upper 

 lids. 



Remarks. — Our specimen from Florencia, Caquetd, was compared 

 directly with the series of cotypes in the British Museum, particularly 

 with BM 80.12.5.181 [1947.2.12.99] from Canelos, Ecuador. There 

 seems to be no determinable significant difference in the series and 

 we must consider all of these specimens as conspecific.
