Description. — USNM 142101, an adult from 50 miles north of Cali, 

 Valle, Colombia, Heavy bony ridges on top of head. Parotoid gland 

 thick and prominent, oval, its length equal to distance from tip of 

 snout to posterior border of eye; tongue half as wide as mouth opening, 

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

 when viewed from above, truncate in profile, the upper jaw scarcely 

 extending beyond the lower. Nostrils lateral, slightly projecting, their 

 distance from end of snout about one-half their distance from eye. 

 Can thus rostrails blunt but distinct; loreal region concave, vertical, 

 merging gradually with the upper lip. Eye large, prominent, its dia- 

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

 little over twice that of upper eyelid, much greater interval between 

 nostrils. Tympanum not very distinct, its greatest diameter a little 

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

 its own diameter. Fingers moderate in length, with very faint, blunt 

 lateral ridges, free, first finger much longer than second, fourth longer 

 than either; a large blunt thumb pad present; a poorly defined round 

 palmer callus; metacarpal tubercles well developed. Toes long, one- 

 half webbed, third toe much longer than fifth, its tip reaching to middle 

 of antepenultimate phalanx of fourth; a heavy, blunt, oval metatarsal 

 tubercle and a rounded outer one; a distinct tarsal ridge, ending near 

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

 axillary region wider than greatest width of head. When hind leg is 

 adpressed, heel fails to reach the shoulder; when limbs are laid along 

 the sides, knee and elbow are widely separated; when hind legs are 

 bent at right angles to body, heels are slightly separated. Skin of 

 upper parts coarsely glandular, with many small tubercles on posterior 

 part of back and sides; a heavy glandular fold along side from parotoid 

 to groin; venter granular, the granules on belly nearly flat, those on 

 throat and chest smaller, a little more raised ; a heavy bony ridge from 

 posterior corner of eye above tympanum, ending at anterior end of 

 parotoid; a pair of wide, blunt scapular ridges; another wide bony 

 ridge from inner posterior corner of eye to nuchal region; a faint skin- 

 fold across the chest; no ventral disk; an external vocal sac in male.
