separated from eye by an interval equal to its own diameter. Fingers 

 quite long, with lateral ridges, free, first finger with a very small disk 

 and much shorter than second, fourth longer than either and reaching 

 to base of disk of third, which covers tympanum and extends beyond 

 for almost one-fourth the width of tympanum; a long cylindrical 

 thumb pad present; a nearly divided palmar callus, its outer part 

 not very distinct; metacarpal tubercles well developed. Toes mod- 

 erately long, distinctly webbed at base, third and fifth toes sub equal, 

 their disks reaching to base of antepenultimate phalanx of fourth 

 toe; disk of fourth toe covering two- thirds the tympanum, and much 

 smaller than that of third finger; a rather flat, cylindrical inner 

 metatarsal tubercle and a much smaller round one; a strong tarsal 

 ridge, ending two-thirds the distance to heel; a distinct skinfold on 

 heel and knee, and a prominent tubercle on heel. Body rather elongate, 

 in postaxillary region narrower than greatest width of head. When 

 hind leg is adpressed, heel reaches to nostrils; when limbs are laid 

 along the sides, knee and elbow touch; when hind legs are bent at 

 right angles to body, heels overlap somewhat. Skin of back and sides 

 very finely granular, of head and upper limb surfaces smooth; a 

 few small tubercles on sacrum, on upper eyelids, and on a faint glan- 

 dular line between the eyes, and a large tubercle at side of back just 

 above axilla; a weak glandular W behind the head; belly and lower 

 and posterior surfaces of femur coarsely granular; chin and chest 

 nearly smooth; throat pustular; a narrow glandular ridge from pos- 

 terior corner of eye above tympanum, ending behind it; a distinct 

 skinfold across chest; a prominent ventral disk; a median external 

 vocal sac in the male. 



Dimensions. — Head and body, 47 mm.; head length, 17 mm.; 

 head width, 16.5 mm.; femur, 21 mm.; tibia, 25 mm.; foot, 20 mm.; 

 hand, 15 mm. 



Color in alcohol. — Dorsum cinnamon, with an indistinct darker W 

 behind the head, and with a dark spot emphasizing the large tubercle 

 on back above axilla; side of body pale wood brown; a seal brown 

 lateral stripe beginning on canthus, darkening above tympanum, 

 continuing on shoulder, becoming lighter and dropping diagonally 

 across the side to belly; a few dusky spots in front of groin; side of 

 head below canthal stripe drab to fawn color, with a few indistinct 

 darker patches below eye; upper surface of femur wood brown, with 

 three narrow, light-margined sepia crossbars which fade out on anterior 

 surface of femur but darken and enlarge to cover the posterior surface, 

 enclosing a few circular light spots representing the light margins of 

 the crossbars on upper part of femur; tibia, foot, and forearm with 

 traces of dark crossbars; soles of feet and palms of hands clay color, 

 their disks and tubercles lighter.
