 Quintana, near Popayan, Cauca, Colombia. Tongue half as wide as 

 mouth opening, oval, its posterior border free and slightly notched; 

 snout broadly rounded when viewed from above, truncate in profile, 

 the upper jaw extending well beyond the lower. Nostrils lateral, 

 scarcely projecting, their distance from end of snout three-quarters 

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

 region faintly concave, sloping outward to the upper lip. Eye large, 

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

 interorbital distance 1% times that of upper eyelid, a little greater 

 than interval between nostrils. Tympanum distinct, its greatest 

 diameter one-half that of eye, separated from eye by an interval 

 equal to three-quarter its own diameter. Fingers fairly long, with 

 lateral ridges, free, first finger equal to second, fourth longer than 

 either and reaching to base of penultimate phalanx of third, the 

 disk of which covers about one-eighth the tympanum; a small oval 

 thumb pad present; a large round palmar callus; metacarpal tubercles 

 well developed. Toes moderate in length, webbed at the base, third 

 toe much longer than fifth, its disk reaching to center of antepenulti- 

 mate phalanx of fourth; disk of fourth toe about one-third the tym 

 panum and larger than that of third finger; a small oval inner 

 metatarsal tubercle and an outer one of about equal size; a faint 

 tarsal ridge ending diagonally across tarsus midway to heel; a heavy 

 skinfold on heel and knee. Body stout, in postaxillary region equal 

 to greatest width of head. When hind leg is adpressed, heel reaches 

 posterior border of tympanum; when limbs are laid along the side, 

 knee and elbow just meet; when hind legs are bent at right angles 

 to body, heels are widely seperated. Skin of upper parts resistant to 

 abrasion, smooth (thickly pustular under the lens) ; a small parotoid 

 swelling extending backwards as a narrow lateral gland, fading out 

 at midbody but again perceptible near the groin; venter smooth 

 (finely pustular with magnification); no skinfold across the chest; a 

 faint ventral disk; a pair of lateral external vocal sacs in the male.
