tongue three-fourths as wide as mouth opening, cordiform, its pos- 

 terior border free and notched; snout moderate, rounded when viewed 

 from above, its tip truncate in profile, the upper jaw extending slightly 

 beyond the lower. Nostrils lateral, slightly projecting, their distance 

 from end of snout about two-thirds their distance from eye. Canthus 

 rostralis heavy but blunt; loreal region concave, flaring outwards to 

 the upper lip. Eye large, prominent, its diameter about four-fifths 

 its distance from tip of snout; interorbital diameter 13^ times the 

 diameter of upper eyelid, equal to interval between nostrils. Tym- 

 panum distinct, at least anteriorly, its greatest diameter one-half 

 that of eye, separated from eye by an interval nearly equal to its 

 own diameter. Fingers long, rather slender, with lateral ridges, free, 

 first finger a trifle shorter than second, fourth longer than either, 

 reaching to base of disk of third, which covers nearly one-half the 

 tympanum; an oval thumb pad present; palmar callus not distinct; 

 metacarpal tubercles well developed. Toes moderately long, webbed 

 at the base, third toe shorter than fifth, its disk reaching almost to 

 penultimate phalanx of fourth; disk of fourth toe covering two- 

 thirds of the tympanum and larger than that of third finger; a weak 

 oval inner metatarsal tubercle and a very small, indistinct outer one; 

 no tarsal ridge; a skinfold and a few small tubercles on heel; a skinfold 

 on knee. Body stout, in postaxillary region equal to greatest width 

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

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

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

 slightly separated. Skin of upper parts smooth (pustular under the 

 lens), with granules on sides and around anus; venter heavily granular 

 on belly and lower femur, smooth on chin and chest; a very heavy 

 glandular ridge from posterior corner of eye above tympanum, ending 

 in a swollen parotoid-like area above and behind ears; a slight skin- 

 fold across chest; a ventral disk; apparently external lateral vocal 

 sacs in the male. 



Dimensions. — Head and body, 43.5 mm.; head length, 14.5 mm.; 

 head width, 18 mm.; femur, 18.5 mm.; tibia, 20 mm.; foot, 20.5 mm.; 

 hand, 15 mm. 



Color in alcohol. — Dorsum russet, with coarse seal brown marblings 

 appearing to begin at the midline and extending backwards and out- 

 wards in very crude chevrons; sometimes a clove brown diagonal line 

 or spot accompanying the marbled pattern; a fine clove brown median 

 line on top of snout; limbs wood brown, with narrow sepia crossbars on 

 upper surfaces; posterior femur ochraceous-buff with two or three 

 large white spots (in fine with the wood brown areas of upper femur) ; 

 venter pinkish buff, immaculate, except for some indistinct darker 

 suffusions on chin and around lower jaw; soles of feet and palms of
