Description. — USNM 147093, an adult male from Mariquita, 

 Tolima, Colombia. Vomerine teeth in two transverse, crescentic, nearly 

 continuous series behind the choanae; tongue two-thirds as wide as 

 mouth opening, broadly oval, its posterior border free and deeply 

 notched; snout long, rounded when viewed from above, but with a 

 ridge around lip border so that in profile the upper jaw appears more 

 or less acuminate and extends considerably beyond the lower. Nostrils 

 dorsolateral, scarcely projecting, their distance from end of snout 

 almost equal to their distance from eye. Can thus rostralis distinct; 

 loreal region nearly flat, sloping to the upper lip. Eye large, prominent, 

 its diameter nearly as great as its distance from tip of snout; inter- 

 orbital diameter equal to that of upper eyelid, equal to interval 

 between nostrils. Tympanum large and distinct, its greatest diameter 

 three-fifths that of eye, separated from eye by an interval equal to 

 one-fourth its own diameter. Fingers short, with lateral ridges, free, 

 first finger longer than second or fourth, reaching to base of ultimate 

 phalanx of third; an oval thumb pad present; a large partly divided 

 palmar callus; metacarpal tubercles well developed. Toes very long, 

 not webbed, third toe much longer than fifth and reaching beyond base 

 of antepenultimate phalanx of fourth; tarsus smooth; an oval inner 

 metatarsal tubercle; outer metatarsal tubercle very small, almost 

 invisible; a heavy tarsal ridge, ending at heel; a heavy skinfold on heel 

 and knee. Body elongate, in postaxillary region smaller than greatest 

 width of head. When hind leg is adpressed, heel reaches nostril; 

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

 legs are bent at right angles to body, heels overlap greatly. Skin of 

 upper parts minutely pustular; a pair of glandular lateral folds, and 

 between them three other pairs of folds which sometimes break up 

 into rows of elongate glands; venter smooth; a heavy skinfold across 

 chest; a ventral disk; a pair of external lateral vocal sacs in the male. 



Dimensions. — Head and body, 54 mm.; head length, 18 mm.;
