Description. — USNM 147035, an adult male from Puerto Narino, 

 Amazonas, Colombia. Vomerine teeth in two wide, slanting, well- 

 separated series behind the choanae; tongue one-half as wide as 

 mouth opening, oval, its posterior border free and unnotched; snout 

 moderate, rounded when viewed from above, with a ridge bordering 

 upper lip in profile, the upper jaw extending considerably beyond the 

 lower. Nostrils dorsolateral, slightly projecting, their distance from 

 end of snout equaling their distance from eye. Canthus rostralis 

 distinct but rounded; loreal region flat, oblique, sloping to the upper 

 lip. Eye large, prominent, its diameter a little less than its distance 

 from tip of snout; interorbital diameter a trifle greater than that of 

 upper eyelid; equal to interval between nostrils. Tympanum distinct, 

 its greatest diameter about three-fifths that of eye, separated from 

 eye by an interval equal to one-half its own diameter. Fingers mod- 

 erate, with faint lateral ridges, free, first, second, and fourth subequal, 

 reaching to base of ultimate phalanx of third finger; a small oval 

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

 developed. Toes long, third toe longer than fifth, and reaching to 

 center of antepenultimate phalanx of fourth; toes with rounded tips 

 which are not wider than the digital articulations; tarsus distinctly 

 granular; a small oval inner metatarsal tubercle and a smaller round 

 outer one; a tarsal ridge, ending near heel; a series of skinfolds on 

 heel and knee. Body rather stout, in postaxillary region narrower 

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

 posterior corner of eye; when limbs are laid along the sides, knee and 

 elbow fail to meet; when hind legs are bent at right angles to body, 

 heels overlap. Skin of upper parts shagreensd, with numerous low 

 glandular ridges especially on sides and sacral region; venter smooth; 

 a distinct glandular ridge from posterior corner of eye above tym- 

 panum, forking, and continuing along the sides, part as a lateral fold 

 and part ending behind tympanum; a skinfold across the chest; a 

 large flat pre-inguinal gland present; a ventral disk; a pair of lateral 

 external vocal sacs in the male.
