upper lip rounding outwards very slightly beyond the loreal region. 

 Eye large and prominent, its diameter equal to its distance from end 

 of snout; interorbital diameter a little greater than that of the rather 

 broad upper eyelid, equal to the distance between nostrils. Tympanum 

 distinct, about one-half the diameter of eye and located immediately 

 behind eye. Fingers moderately long, free, without lateral ridges, 

 with small disks, disk of third finger covering about one-eighth the 

 tympanum; first finger longer than second, fourth rather short; 

 subarticular tubercles of fingers very large; a large palmar tubercle 

 present, third and fourth toes with a very short web between them, 

 the other toes without webs; disk of fourth toe covering almost one- 

 half the tympanum; third toe longer than fifth, reaching halfway on 

 antepenultimate phalanx of fourth; subarticular tubercles of toes 

 very small; a heavy, short, transverse glandular ridge across tarsus 

 about one-third the way from inner metatarsal tubercle to heel 

 (which suggests the tarsal tubercle found in some species of Physalae- 

 mus) ; a small but distinct inner metatarsal tubercle and a smaller 

 outer one; subarticular tubercles of toes smaller and less evident than 

 those of fingers. No inguinal or lumbar gland. Body rather elongate, 

 in postaxillary region equal to greatest width of head ; when hind legs 

 are ad pressed, heel reaches to center of eye; when limbs are laid along 

 the sides, knee and elbow greatly overlap ; when hind legs are bent at 

 right angles to body, heels slightly overlap. Skin not easily torn, 

 coarsely granular on back, finely granular on tip of snout and on side 

 of body; skin of arms nearly smooth, that of upper leg surfaces 

 coarsely granular; venter smooth.

Color in alcohol. — Dorsum black, with a narrow white dorsolateral 

 line from above nostril, above eye, and straight backward along side; 

 a large squarish white spot in upper part of groin and another at 

 armpit; a narrow white lateral line from below arm along side to 

 lower anterior part of groin; legs barred with lighter slate gray diago- 

 nal bars; throat and chest black; belly and lower leg surfaces white 

 with many large black spots; palms of hands and soles of feet spotted 

 heavily with black, their corresponding upper surfaces white with a 

 few black dots. A white line beginning below nostril andrunnin g 

 along edge of upper lip and to the shoulder ends in a large crescentic 

 white patch; a second white line beginning below nostril, continuing 

 on edge of upper lip, below tympanum, above arm insertion, and 

 straight back to leg insertion; a third white line, very irregular in 

 outline, from axilla to groin along lateroventral border and paralleling 

 the two upper lines; venter slate-gray anteriorly, the posterior half of
