Description. — USNM 144910, an adult male from Barranquilla, 

 Atlantico, Colombia. Vomerine teeth absent; tongue two-thirds as 

 wide as mouth opening, very broadly ovate, its posterior border free 

 and slightly notched; snout short, rounded when viewed from above, 

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

 Nostrils dorsolateral, scarcely projecting, almost terminal, their 

 distance from end of snout scarcely one-fourth their distance from eye. 

 Can thus rostralis bluntly rounded; loreal region flat, sloping outward 

 to the upper lip. Eye large, prominent, its diameter equal to its 

 distance from tip of snout; interorbital diameter about three-quarters 

 that of upper eyelid, a trifle greater than distance between the nostrils. 

 Tympanum small but distinct, its greatest diameter one-half that of 

 eye, separated from eye by an interval equal to its own diameter. 

 Fingers moderate, the tips not enlarged, free, first finger longer than 

 second or fourth, its tip reaching to base of ultimate phalanx of third; 

 a small oval thumb pad present; a larger rounded palmar callus; 

 metacarpal tubercles well developed. Toes quite short, webbed at the 

 base, with distinct lateral ridges, third and fifth toes subequal, their 

 tips reaching to base of antepenultimate phalanx of fourth toe; 

 a heavy semilunar inner metatarsal tubercle and a somewhat larger, 

 more rounded, shovel-shaped outer one; a faint tarsal ridge, ending 

 halfway to heel; a heavy skinfold on heel and knee. Body very stout, 

 in postaxillary region nearly equal to the head width. When hind leg is 

 adpressed, heel reaches front of shoulder; when limbs are laid along 

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

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

 parts faintly pustular, the pustules most apparent on top of head; an 

 oval gland slightly longer than snout above groin on flank, not 

 concealed when hind legs are folded; several smaller and less-distinct 

 glands on back and sides; venter smooth, except for some small 

 pustules below the anus. A broad, low glandular ridge from posterior 

 corner of eye above tympanum, ending in front of the swollen temporal 

 area behind tympanum. A heavy skinfold across chest; a very promin- 

 ent ventral disk, the skin of posterior belly in fine wrinkles paralleling 

 the outlines of disk; a median external vocal sac.

 head width, 16 mm.; femur, 15 mm.; tibia, 14 mm.; foot, 13.5 mm.;
