Description.— USNM 4347a (holotype), an adult male from near 

 Turbo, Antioquia, Colombia. Vomerine teeth in two heavy, transverse, 

 arc-shaped, narrowly separated series on a level with posterior borders 

 of choanae; tongue two-thirds as wide as mouth opening, ovate, its 

 posterior border free and slightly notched; snout moderate in length, 

 rounded when viewed from above and in profile, the upper jaw ex- 

 tending well beyond the lower. Nostrils dorsolateral, slightly project- 

 ing, their distance from end of snout one-half their distance from eye. 

 Can thus rostralis blunt; loreal region concave, sloping outwards to the 

 upper lip. Eye large, prominent, its diameter four-fifths its distance 

 from tip of snout; interorbital diameter equal to that of upper eyelid, 

 equal to interval between nostrils. Tympanum large, its greatest 

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

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

 ridges, free, first finger longer than second and fourth, reaching to 

 base of ultimate phalanx of third; a heavy oval thumb pad present; a 

 distinct triangular palmar callus; metacarpal tubercles well developed. 

 Toes long, third toe longer than fifth reaching to middle of ante- 

 penultimate phalanx of fourth; a small projecting inner metatarsal 

 tubercle and a much smaller round outer one; a strong tarsal ridge, 

 ending near heel; a strong skinfold on heel and knee. Body rather 

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

 When hind leg is adpressed, heel reaches a point between eye and 

 nostril; when limbs are laid along the sides, knee and elbow slightly 

 overlap; when hind legs are bent at right angles to body, heels overlap. 

 Skin of upper parts pustular, with a wide dorsolateral ridge from 

 posterior corner of eye to level of groin and a shorter lateral one from 

 behind ear to groin; venter smooth, except for some granules on pos- 

 terior femur; a sharp glandular ridge from posterior corner of eye 

 above tympanum, ending in a widened gland behind tympanum; a 

 distinct skinfold across chest; a prominent ventral disk; no external 

 vocal sacs in the male.
