long, rounded when viewed from above and in profile, the upper jaw 

 extending well beyond the lower. Nostrils dorsolateral, slightly pro- 

 jecting, their distance from end of snout about two-fifths their distance 

 from eye. Can thus rostralis distinct, straight; loreal region concave, 

 sloping outwards to the upper lip. Eye large, prominent, its diameter 

 three-fourths its distance from tip of snout; interorbital diameter equal 

 to that of upper eyelid, and to interval between nostrils. Tympanum 

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

 by an interval equal to two-thirds its own diameter. Fingers long, 

 with pronounced lateral ridges, free, first finger a little shorter than 

 second, fourth longer than either and reaching to base of disk of third, 

 which covers the whole tympanum; a narrow oval thumb pad present; 

 a very indistinct small palmar callus; metacarpal tubercles well 

 developed. Toes free or very slightly webbed, very long, third toe 

 shorter than fifth, the disk of which reaches to base of antepenultimate 

 phalanx of fourth; disk of fourth toe covering the tympanum and 

 equal to that of third finger; a small but pronounced inner metatarsal 

 tubercle and a very indistinct smaller outer one; a narrow tarsal ridge, 

 ending midway to heel; a heavy skinfold on heel and knee. Body 

 elongate, in postaxillary region narrower than greatest width of head. 

 When hind leg is ad pressed, heel reaches far beyond snout; when 

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

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

 upper parts shagreened, with a few very small granules on sides and 

 on sacral region; chest, throat, and anterior half of belly smooth; 

 posterior half of belly, lower proximal parts of femur and below anus 

 granular; a heavy glandular ridge from posterior corner of eye above 

 tympanum, ending above shoulder; a slight skinfold across the chest; 

 indications of a weak ventral disk; a median external vocal sac in 

 the male. 



Dimensions. — Head and body, 59 mm.; head length, 21 mm.; head 

 width, 20.5 mm.; femur, 32 mm.; tibia, 38 mm.; foot, 35.5 mm.; 

 hand, 18 mm. 



Color in alcohol. — Dorsum dull russet; a clove brown band between 

 the eyes; a pair of wide longitudinal clove brown stripes down either 

 side of middorsal area, which is russet, the lateral margins of these 

 clove brown stripes indistinct, but gradually lightening to cinnamon 

 on the sides, where a series of four or five short diagonal rows of black 

 spots begins just behind the axilla, continuing to groin and becoming 

 larger there; a similar series of black spots, sometimes fusing into bars, 

 on anterior and top of femur, abruptly ending in a rounded prolonga- 

 tion midway down the posterior femur and being outlined with a 

 pale fawn-colored line near their termination; lower part of posterior
