Description. — CNHM 43850, an adult male from Cisneros, Valle, 

 Colombia. Head flat above, its length about 1% times its width, due 

 to elongated snout; tongue a little less than half as wide as mouth 

 opening, very long, spatulate, its posterior border free and unnotched; 

 snout bluntly pointed when viewed from above, nearly right-angled 

 at tip, concave and receding in profile, the upper jaw extending con- 

 siderably beyond the lower. Nostrils lateral, small, scarcely projecting, 

 their distance from end of snout equal to their distance from eye. 

 Can thus rostralis straight and sharp; loreal region slightly concave, 

 descending almost vertically to the upper lip. Eye large, prominent, 

 its diameter about seven-eighths its distance from tip of snout; inter- 

 orbital diameter nearly three times that of upper eyelid, a little 

 greater than interval between nostrils. Tympanum not very distinct, 

 its greatest diameter one-third that of eye, separated from eye by an 

 interval equal to its own diameter. Fingers rather long, slender, with 

 lateral ridges, the three outer ones webbed at base, first and second 

 one-half webbed and quite short, first finger much shorter than second, 

 fourth longer than either and reaching to base of penultimate phalanx 

 of third; finger disks bulbous but not greatly enlarged; a small oval 

 thumb pad present; a flat, round palmar callus; metacarpal tubercles 

 poorly developed. Toes long, one-half webbed, the outer two entirely 

 webbed, third and fifth subequal, their tips reaching to base of ante- 

 penultimate phalanx of fourth toe; a small oval inner metatarsal 

 tubercle and a larger rounded outer one; apparently a tarsal ridge, 

 ending near heel; a skinfold on heel and knee. Body elongate, in post- 

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

 adpressed, heel probably reaches to center of eye (not possible to 

 acertain in the stiffened specimen) ; when limbs are laid along the 

 sides, knee and elbow touch; when hind legs are bent at right angles 

 to body, heels touch. Skin of upper parts thin, pustular under the lens, 

 adhering to vertebrae, which are very prominent; venter finely 

 pustular, with coarse pustules on chin and throat and wrinkles on 

 belly; a sharp glandular ridge from posterior corner of eye, projecting 

 above tympanum, ending above shoulder; a light skinfold across the 

 chest; no ventral disk.

 width, 13 mm.; femur, 19.5 mm.; tibia, 19.5 mm.; foot, 14.5 mm.;
