Description. — USNM 146991, an adult from Tequendama Falls, 

 Cundinamarca, Colombia. No bony ridges on top of head; a distinct 

 frontoparietal depression. Vomerine teeth in two very weak, well- 

 separated patches behind the choanae; tongue two-thirds the width 

 of mouth opening, squarish, with a slight notch on its free posterior 

 border; snout moderately long, pointed at the tip when seen from 

 above, more rounded in profile, the upper jaw projecting considerably 

 beyond the lower, which is nearly truncate anteriorly; nostrils super- 

 olateral, their distance from end of snout two-thirds their distance 

 from eye. Canthus rostralis thick and rounded, with a heavy furrow 

 between it and the flat loreal region which merges with the flaring 

 upper lip. Eye large and prominent, its diameter about three-fourths 

 the snout length; interorbital diameter 1% times the width of upper 

 eyelid and 1% times the interval between nostrils. Tympanum dis- 

 tinct, its diameter about two-fifths that of eye, and separated from 

 eye by about one-fourth its own diameter. Fingers moderate, free, 

 with very wide lateral ridges, first finger much shorter than second, 

 which in turn is shorter than fourth, tip of fourth finger reaches to 

 base of penultimate phalanx of third; disk of third finger covering 

 four-fifths of tympanum; a small crescentic pad at base of first finger; 

 two or three small, weak pads on palm of hand; metacarpal tubercles 

 well developed; toes long, free, with wide lateral ridges, third toe 

 much shorter than fifth, which reaches almost to base of penultimate 

 phalanx of fourth; toe disks a little larger than finger disks, disk of 

 fourth toe completely covering the tympanum; a small round inner 

 and a very small outer metatarsal tubercle; a prominent tarsal ridge 

 extending nearly to heel. Body moderate, in postaxillary region 

 narrower than the relatively wide head. When hind leg is adpressed, 

 heel reaches to nostril; when limbs are laid along the sides, knee 

 and elbow slightly overlap; when hind legs are bent at right angles 

 to body heels greatly overlap. A. short supratympanic ridge, fading 

 out above the shoulder. A narrow glandular median dorsal line from 

 tip of snout to anus. Skin above minutely pustular, with small scattered 

 tubercles on snout, a group of several heavy tubercles above shoulder, 

 and similar but less prominent ones on each side of sacrum; a group 

 of small, pointed tubercles in area behind tympanum and on each 

 eyelid; chin faintly tubercular, chest and belly and posterior femur
