 Meta, Colombia. Tongue two-fifths as wide as mouth opening, elongate, 

 oval, its posterior border free and unnotched; snout moderate, rounded 

 when viewed from above, rounded in profile, the upper jaw extending 

 well beyond the lower. Nostrils dorsolateral, projecting, their distance 

 from end of snout about one-half their distance from eye; Can thus 

 rostralis blunt, rounded; loreal region concave, with a deep furrow 

 on its lower margin above the upper lip. Eye large, prominent, its 

 diameter about two-thirds its distance from tip of snout; interorbital 

 diameter equal to that of upper eyelid, equal to interval between 

 nostrils. Tympanum indistinct, its greatest diameter apparently 

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

 to one-half its own diameter. Fingers and toes with slightly enlarged 

 terminal disks; fingers long, with distinct lateral ridges, free, first 

 finger shorter than second, which equals the fourth, second and

 prominent outer one; a diagonal tarsal ridge ending midway to heel

 in postaxillary region equal to greatest width of head. When hind 

 leg is adpressed, heel reaches anterior border of eye; when limbs are 

 laid along the side, knee and elbow are slightly separated; when 

 hind legs are bent at right angles to body, heels just touch. Skin 

 of upper parts very pustular, the pustules forming small rounded 

 glands on head and along dorsolateral area; an X-shaped gland between
