Description. — MLS 196, La Selva, Norte de Santander, Colombia. 

 Vomerine teeth absent; the choanae small, rounded; tongue about one- 

 half as wide as mouth-opening, elongate, its posterior third free and 

 shallowly notched. Snout short, U-shaped when viewed from above, 

 rounded in profile, the upper jaw extending but very slightly beyond 

 lower; nostrils more lateral than superior, slightly projecting, their 

 distance from end of snout about one-half that from eye, separated 

 from each other by an interval equal to about their distance from eye. 

 Can thus rostralis slightly denned; loreal region flat and slightly 

 oblique, the upper lip flaring out a little below it. Eye moderate, not 

 prominent, its diameter equal to its distance from nostril; palpebral 

 membrane not reticulate; interorbital distance about equal to width 

 of upper eyelid, which is relatively wide and slightly greater than dis- 

 tance between nostrils. Tympanum very distinct, about one-third the 

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

 third its own diameter. Fingers entirely without webs, fourth finger a 

 little longer than second, just reaching to disk of third which slightly 

 more than covers the tympanic area; no projecting rudiment of a 

 pollex; no ulnar ridge; toes without webs, third and fifth subequal, disk 

 of fourth toe as large as disk of third finger and slightly more than 

 covering the tympanic area; tubercles very indistinct; no tarsal ridge; 

 no dermal appendage on heel. Body short, in postaxillary region a little 

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

 reaches tip of snout; when limbs are laid along the sides, knee and 

 elbow overlap considerably; when hind legs are bent at right angles to 

 body, heels overlap greatly. No patagium extends from back of upper 

 arm to side of body. Skin of upper parts smooth; a rather well devel- 

 oped narrow glandular ridge encircling upper part of tympanum; skin 

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

 uniformly and very finely granular; traces of a skinfold across chest; 

 adult male, vocal sac subgular.
