merine teeth in two transverse, short, narrowly separated series behind 

 the choanae; tongue moderate, one-half as wide as mouth opening, 

 squarish, its posterior border free and distinctly notched; snout 

 moderately elongate, rounded when viewed from above and in profile 

 the upper jaw projecting well beyond the lower jaw, which is quite 

 truncate and somewhat concave anteriorly. Nostrils lateral, dis- 

 tinctly projecting, their distance from end of snout two-third their 

 distance from eye. Can thus rostralis definite and angular; loreal 

 region concave, with a slight furrow along border of upper lip. Eye 

 large, prominent, its diameter about fourth-fifths its distance from 

 tip of snout; interorbital diameter X% times that of upper eyelid, a 

 little greater than interval between nostrils. Tympanum small but 

 distinct, its greatest diameter two-fifths that of eye, separated from 

 eye by an interval equal to three-fourths its own diameter. Fingers 

 long, without lateral ridges, free, first finger shorter than second and 

 with a small disk, fourth longer than either, reaching midway on 

 penultimate phalanx of third, which nearly covers the tympanum; 

 a rounded thumb pad present; a cordiform palmar callus; metacarpal 

 tubercles well developed. Toes faintly webbed, very long, third toe 

 longer than fifth, its disk reaching to base of antepenultimate phalanx 

 of fourth; disk of fourth toe covering two-thirds the tympanum, and 

 smaller than that of third finger; a small but distinct inner metatarsal 

 tubercle and a smaller round outer one; a faint tarsal ridge, ending 

 three-fourths of the distance to heel; a heavy skinfold on heel and 

 knee, the heel with a pronounced skin tubercle. Body elongate, in 

 postaxillary region narrower than greatest width of head. When 

 hind leg is adpressed, heel reaches a point between eye and nostril; 

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

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

 Skin of upper parts faintly pustular, with a weak glandular middorsal 

 furrow and minute round dorsal pustules which are a little coarser 

 on the sacrum; venter coarsely granular on posterior two- thirds of 

 belly, on posterior proximal part of femur, and below vent, smooth 

 on chest, finely pustular on throat and chin; a heavy glandular ridge 

 from posterior corner of eye, above tympanum, becoming smaller and 

 ending above shoulder; two or three flat glandular warts at angle of 

 jaw; a slight skinfold across chest; a large ventral disk. 



Dimensions. — Head and body, 28 mm.; head length, 11 mm.; 

 head width, 10.5 mm.; femur, 11.5 mm.; tibia, 16 mm.; foot, 13 mm.; 

 hand, 8.5 mm. 



Color in alcohol. — Top of head and middorsal area ochraceous;
