upper jaw projecting considerably beyond lower; nostrils lateral, their 

 distance from end of snout one-half their distance from eye, separated 

 from each other by an interval equal to three-fourths their distance 

 from eye. Canthus rostralis sharp; loreal region flat, the upper lip 

 flaring outwards below it. Eye large, very prominent, its diameter 

 four-fifths the length of snout; interorbital diameter slightly greater 

 than width of upper eyelid, IK times the distance between nostrils. 

 Tympanum distinct, one-half the diameter of eye, separated from eye 

 by two-thirds its own diameter. Fingers rather short, free, second 

 shorter than fourth, first longer than second and fourth, all with 

 rounded tips, which are only slightly dilated ; a heavy pointed elongate 

 pad at base of first finger and a flattened oval one on palm; all meta- 

 carpal tubercles very greatly developed; toes moderately long, free, 

 with slightly dilated tips, third slightly longer than fifth and reaching 

 to base of antepenultimate phalanx of fourth; a small conical inner 

 metatarsal tubercle and a rounded, flat outer one; metatarsal tubercles 

 very well developed, those below the proximal joints being larger than 

 the inner metatarsal tubercle; no tarsal ridges, instead a row of weak 

 round or elongate glandules on outside of tarsus. Body rather stout, 

 in postaxiUary region equal to greatest head width. "When hind leg is 

 adpressed, heel reaches a little beyond tip of snout; when limbs are 

 laid along the side, knee and elbow greatly overlap; when hind legs 

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

 minutely glandular, with 8 to 10 fine, broken, sinuous granular ridges 

 from posterior half of each eyelid to the sacral region; some small 

 granules above coccyx, extending onto posterior femur; a narrow, 

 distinct supratympanic ridge, with rounded heavy glandules at corner 

 of mouth and smaller ones in front of tympanum. Venter smooth, 

 with a prominent ventral disk. No apparent external vocal sac. 



Dimensions. — Head and body 54 mm.; head length 21 mm., width 

 21 mm.; femur 26 mm.; tibia 30 mm.; foot 26 mm.; hand 14 mm. 



Color in alcohol. — Dorsum pale olive-yellow; a dark brown stripe 

 along canthal region; a pair of light brown spots where the glandules 

 end at sacrum; three pale gray crossbars on femur and tibia, and one or 

 two fainter ones on forearm; upper lip pale gray, with traces of light 

 diagonal bars in front of and behind the eye; venter immaculate pale 

 buff. 



Color in life. — Upper surface clay color tinged with vinaceous-buff. 

 A clove-brown stripe along the canthus, ending behind ear, and a 

 clove-brown stripe along outer side of tibia. Pupil gold above, with 

 a brown line through it; below more coppery and greenish, the enthe 

 area sprinkled with fine black dots. 



Remarks. — This species appears to be less common than E. guentheri 

 although it is by no means rare. The short second finger makes this
