Description. — USNM 147232, an adult female from Pizarro, Choc6, 

 Colombia. No bony ridges on top of head. Vomerine teeth in two 

 long, widely separated, slanting series behind the choanae; tongue 

 slightly more than half as wide as mouth opening, oval, its posterior 

 border free and unnotched; snout short, bluntly rounded when viewed 

 from above, nearly truncate in profile, the upper jaw extending some- 

 what beyond the lower, which is truncate anteriorly. Nostrils supero- 

 lateral, slightly projecting, their distance from end of snout about 

 two-thirds their distance from eye, separated from each other by an 

 interval equal to their distance from eye. Canthus rostralis rounded; 

 loreal region concave, sloping outwards to the upper lip. Eye large, 

 prominent, its diameter equal to its distance from tip of snout; 

 interorbital diameter IK times that of upper eyelid, equal to interval 

 between nostrils. Tympanum very small, its greatest diameter one- 

 third that of eye, separated from eye by an interval equal to its own 

 diameter. Fingers short, without lateral ridges, free, second and fourth 

 fingers subequal, first finger much shorter than either; disks of fingers 

 large, that of third finger about twice the tympanic area; a small 

 oval thumb pad present; a very small palmar callus; metacarpal 

 tubercles weak, scarcely visible. Toes with barely perceptible traces 

 of webs, short, third toe shorter than fifth, the disk of fifth reaching 

 to base of penultimate phalanx of fourth; disks of toes a little larger 

 than those of fingers, disk of fourth toe covering more than twice the 

 tympanic area; a small, blunt, oval outer metatarsal tubercle and a 

 round inner one of about the same size; no tarsal ridge; a heavy skin- 

 fold on heel and knee. Body rather elongate, in postaxillary region 

 slightly narrower than greatest width of head. When hind leg is 

 adpressed, heel reaches to center of eye; when limbs are laid along the 

 sides, heel and elbow are separated; when hind legs are bent at right 

 angles to body, heels are well separated. Skin of upper parts smooth 

 except for some very small tubercles on snout; venter smooth except 

 for a granular area around vent and on lower femur; a weak glandular 

 ridge from posterior corner of eye above tympanum, ending about
