greater than that of body, very slightly constricted. Snout broadly 

 depressed, its contour as viewed above well convex. Eye moderate, 

 about 1| to snout tip. Mouth large, rictus extending back to hind 

 eye edge. Lips as rather thin skin. Maxillary teeth uniserial, 

 uniform, conic, hidden by lip. Vomerine teeth few, conic, slightly 

 hooked, form nearly continuous series between internal nares, so 

 that on level with posterior portion near edge of latter. Vomerine 

 teeth would form very obtuse angle, latter directed posteriorly. 

 Tongue large, orbicular, free for about last third, and hind edge well 

 notched. Internal nares large. External nares rather close, so 

 they fall slightly within median third of antero-interorbital width, 

 Canthus rostralis distinct, not conspicuous. Interorbital slightly 

 concave. Tympanum rather small, rounded, its length 1| in eye. " 



Skin largely smooth above, granulate below, with granules on 

 belly and lower sides much largest. Groin, hind part of pelvis and 

 region around tympanum granulated. Lower surfaces of fore limbs 

 and femora finely granulated. 



Limbs all slender. Fingers with slight basal webs. First finger 

 longer than second, dilated basally or with adnate pollex, third longest, 

 and tips of all with well-developed rounded flat disks, each of which 

 less than size of tympanum. Toes slender, fourth much longest, all 

 rather well webbed basally or for half their extent, and distal disks 

 similar to those of fingers. A rudimentary hallux in form of cuneate 

 compressed tubercle at base of first toe on inside, though not free 

 and much less in extent than that of first finger. A slight tarsal fold 

 along inner edge. 



Color in alcohol slaty above, with two broad more or less complete 

 darker lengthwise bands. These bands extend from each eye above 

 to hind side of pelvis, though broken a little posteriorly. Tympanum 

 in a similar-colored blotch. Sides of body slightly more grayish in 

 general color, with rather numerous rounded dark spots towards 

 and in groin. Upper surfaces of limbs like back, with irregular 

 darker blotches. All darker markings have slightly paler edges than 

 body-color. Lower surface of body pale or nearly plain dull brownish. 

 Hind surfaces of tibia and femora mottled dark slaty and whitish.
