Description. — UF 8544-2, an adult male from Leticia, Amazonas, 

 Colombia. Vomerine teeth in two heavy, triangular, narrowly sepa- 

 rated series behind the choanae; tongue two-thirds as wide as mouth 

 opening, nearly oval, its posterior border free and distinctly notched; 

 snout moderately long, rounded when viewed from above, rounded 

 in profile, the upper jaw extending well beyond the lower. Nostrils 

 dorsolateral, slightly projecting, their distance from end of snout 

 about two-thirds their distance from eye. Can thus rostralis distinct; 

 loreal region flat, vertical, sloping outward to the upper lip. Eye 

 large, prominent, its diameter about five-sixths its distance from tip 

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

 to interval between nostrils. Tympanum distinct, its greatest di- 

 ameter two-thirds that of eye, separated from eye by an interval 

 equal to one-fourth its own diameter. Fingers moderately long, 

 their tips not enlarged, with lateral ridges, free, first finger longer 

 than second, fourth shorter than either, tip of first reaching midway 

 on penultimate phalanx of third; a prominent oval thumb pad present, 

 and, in the male, a black-tipped spine on pad and another below 

 basal metacarpal tubercle; a slightly larger rounded palmar callus; 

 metacarpal tubercles large and well developed. Toes long, webbed at 

 the base, with wide dermal fringes, third toe much longer than fifth, 

 its tip reaching halfway on antepenultimate phalanx of fourth; a 

 small oval inner metatarsal tubercle and a smaller round outer one; 

 tarsus not granular; a heavy tarsal ridge, ending just before reaching 

 heel; a distinct skinfold on heel and knee. Body fairly stout, in post- 

 axillary region equal to greatest width of head. When hind leg is 

 adpressed, heel reaches posterior border of eye; when limbs are laid 

 along the sides, knee and elbow touch; when hind legs are bent at 

 right angles to body, heels slightly overlap. Skin of upper parts 

 shagreened with minute pustules; a short glandular ridge above
