Description. — USNM 76957, an adult male from Old Providence 

 Island, [San Andres y Providencia,] Colombia. Vomerine teeth in two 

 heavy, well-separated, chevron-shaped series behind the choanae; 

 tongue three-fifths as wide as mouth opening, cordiform, its posterior 

 border free and deeply notched; snout moderate, rounded when viewed 

 from above and in profile, the upper jaw extending well beyond the 

 lower. Nostrils dorsolateral, projecting, their distance from end of snout 

 two-thirds their distance from eye. Canthus rostralis rounded and not 

 very distinct; loreal region flat, sloping outwards to the upper lip. Eye 

 large, prominent, its diameter two-thirds its distance from tip of snout; 

 interorbital diameter equal to diameter of upper eyelid, a little less 

 than interval between nostrils. Tympanum large, distinct, its greatest 

 diameter three-fourths that of eye, separated from eye by an interval 

 equal to one-half its own diameter. Fingers moderate, with lateral 

 ridges, free, first finger a little longer than second and equal to fourth, 

 which reaches halfway on penultimate phalanx; two horny black- 

 tipped thumb spines in the male; a heavy thumb pad present; a small 

 palmar callus; metacarpal tubercles well developed. Toes long, with 

 slight webs at their bases which are prolonged as lateral ridges almost to 

 the tips; third toe longer than fifth and reaching halfway on ante- 

 penultimate phalanx of fourth; tarsus smooth; a small oval inner 

 metatarsal tubercle and a smaller round outer one; a narrow tarsal 

 ridge, ending at heel; a pronounced skinfold on heel and knee. Body 

 stout, in postaxillary region narrower than greatest width of head. 

 When hind leg is ad pressed, heel reaches to nostril; when limbs are 

 laid along the sides, knee and elbow overlap; when hind legs are bent 

 at right angles to body, heels overlap. Skin of upper parts finely sha- 

 green ed, with coarse pustules on sacrum; a dorsolateral glandular line
