the lower. Nostrils dorsolateral, distinctly projecting, their distance 

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

 rostralis sharp and distinct; loreal region slightly concave, sloping 

 outwards to the upper lip. Eye relatively small but prominent, its 

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

 area plane, its diameter nearly twice that of upper eyelid and con- 

 siderably greater than interval between nostrils. Tympanum distinct 

 but small, its greatest diameter one-half that of eye, separated from 

 eye by an interval equal to its own diameter. Fingers moderately 

 long, with very small disks, without lateral ridges, free, first finger 

 shorter than second, fourth longer than either and reaching to base 

 of disk of third, which covers about one-fourth the tympanum; an 

 oval thumb pad present; a cordiform palmar callus; metacarpal 

 tubercles well developed. Toes rather short and also with small disks, 

 webbed slightly, third toe a little shorter than fifth, the disk of which 

 reaches to base of antepenultimate phalanx of fourth; disk of fourth 

 toe covering one-fourth the tympanum, and about the same size as 

 that of third finger; a rather flat oval inner metatarsal tubercle and a 

 smaller round outer one; an ill-defined tarsal ridge, ending halfway 

 to heel; a prominent skinfold on heel and knee. Body stout, in post- 

 axillary region narrower than greatest width of head. When hind leg 

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

 along the sides, knee and elbow are widely separated; when hind 

 legs are bent at right angles to body, heels fail to meet. Skin of upper 

 parts finely granular, with an interrupted middorsal row of glands, 

 and three rows of similar glands on each side, the outer one dorsolateral 

 in position; a prominent ( )-shaped gland behind the occiput; small 

 tubercles on top of head and arms, larger ones on upper leg surfaces ; 

 venter coarsely granular excepting the chin, which is faintly granular ; 

 a round flat gland, somewhat larger than the other granules, in post- 

 axillary region; a glandular ridge from posterior corner of eye above 

 tympanum, thickening greatly and ending above shoulder in two 

 heavy glands; a distinct skinfold across chest; a ventral disk; a pair 

 of lateral external vocal sacs in the male. 



Dimensions. — Head and body, 21.5 mm.; head length, 7.5 mm.; 

 head width, 8.5 mm.; femur, 7.5 mm.; tibia, 8 mm.; foot, 7.5 mm.; 

 hand, 6 mm. 



Color in alcohol. — Dorsum burnt umber to Vandyke brown, with the 

 bases of the longitudinal glands and larger tubercles outlined with 

 clove brown; side of head wood brown, with a large indistinct russet 

 spot in front of and behind the eye extending to edge of upper lip; 

 can thai region faintly suffused with sepia; upper limb surfaces van- 

 dyke brown, except knees, elbows, and upper parts of feet and hands, 

 which are wood brown; side of body wood brown with many small
