Description. — USNM 145134, an adult male from Gorgona Island, 

 sea level to 90 meters, Colombia. Faint parallel bony ridges on top 

 of head between the eyes. Vomerine teeth in two short, heavy, trans- 

 verse, widely separated series behind the choanae; tongue one-half as 

 wide as mouth opening, oval, its posterior border free and unnotched; 

 snout nearly truncate at tip when viewed from above, truncate in 

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

 lateral, strongly projecting, their distance from end of snout about 

 one-third their distance from eye. Canthus rostralis rounded; loreal 

 region slightly concave, flaring outwards to the upper lip. Eye large, 

 prominent, its diameter equal to its distance from tip of snout; 

 interorbital diameter 2% times that of upper eyelid, a little greater 

 than interval between nostrils. Tympanum small but distinct, its 

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

 interval equal to two-third its own diameter. Fingers very short, 

 their disks pointed, with lateral ridges and very small webs at the 

 base, first finger much shorter than second, fourth longer than either, 

 its disk reaching to base of disk of third, which nearly covers the 

 tympanum; a crescentic thumb pad present; an indistinct palmar 

 callus; metacarpal tubercles scarcely developed. Toes short, nearly 

 one-fourth webbed, third toe shorter than fifth, the disk of which 

 reaches almost to base of antepenultimate phalanx of fourth; disk of 

 fourth toe nearly covering the tympanum and equal to that of third 

 finger; a very small inner metatarsal tubercle; outer metatarsal 

 tubercle absent; no true tarsal ridge; a distinct skinfold on heel and 

 knee. Body short, in postaxillary region narrower than greatest width 

 of head. When hind leg is adpressed, heel reaches posterior corner 

 of eye; when limbs are laid along the sides, knee and elbow touch; 

 when hind legs are bent at right angles to body, heels are slightly 

 separated. Skin of upper parts smooth, with a few short, weak glandu- 

 lar lines above shoulders and along sides; venter smooth except for 

 some fine transverse ridges across throat, and some granules behind 

 vent and on posterior femur; a very indistinct glandular ridge from
