Desertion. — CNHM 54597, an adult from La Selva, Pueblo Rico, 

 Caldas, Colombia. Vomerine teeth in two heavy, narrowly separated, 

 transverse triangular series behind the choanae; tongue half as wide 

 as mouth opening, thick, cordiform, its posterior border free and 

 distinctly notched; snout broadly rounded when viewed from above, 

 straight and sloping forwards in profile, the upper jaw extending 

 slightly beyond the lower. Nostrils dorsolateral, slightly projecting, 

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

 Canthus rostralis blunt; loreal region nearly flat, sloping strongly to 

 the upper lip. Eye large, prominent, its diameter about five-sixths its 

 distance from tip of snout; interorbital diameter three-fourths that of 

 upper eyelid, equal to interval between nostrils. Tympanum small 

 but distinct, its greatest diameter a little less than one-third that of 

 eye, separated from eye by an interval equal to IK times its own 

 diameter. Fingers fairly short, their tips bulbous but scarcely en- 

 larged, with faint lateral ridges, free, first finger longer than second 

 and equal to fourth, the tip of which reaches to base of penultimate 

 phalanx of third; a large elongate thumb pad present; a weak palmar 

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

 eighth webbed, third toe much longer than fifth, its disk reaching to 

 base of antepenultimate phalanx of fourth; disk of fourth toe covering 

 about one-half the tympanum and much better developed than disks 

 of fingers; a prominent, elongate inner metatarsal tubercle, the outer 

 one scarcely visible; a faint tarsal ridge, ending halfway to heel; a 

 heavy skinfold on heel and knee. Body very stout, in postaxillary 

 region nearly equal to greatest width of head. When hind leg is ad- 

 pressed, heel reaches anterior 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 overlap. Skin of upper parts shagreened, 

 and with small tubercles or short rows of glands thickly scattered 

 everywhere; several enlarged tubercles on upper eyelid; venter smooth, 

 except for some transverse ridges across posterior belly; a short, wide 

 glandular ridge from posterior corner of eye, ending above tympanum; 

 a weak skinfold across the chest; a ventral disk; a median external 

 vocal sac in the male.
