cave ; nostril a lit tie nearer to the tip of the snout than to the eye ; 

 interorbital space as broad as the upper eyelid ; tympanum small, 

 often rather indistinct, not more than two fifths the diameter of 

 the eye. Fingers moderate, depressed, first not extending quite 

 as far as second; toes webbed to the disks ; tips of fingers and toes 

 dilated into very large disks, that of the third finger larger than the 

 tympanum ; subarticular tubercles large ; inner metatarsal tu- 

 bercle oval, flat ; outer metatarsal tubercle very indistinct or absent ; 

 no tarsal fold. The tibio-tarsal articulation reaches beyond the 

 tip of the snout; tibia as long as the trunk. Skin smooth or 

 granulate above ; sides with larger glandules ; a fold above the 

 tympanum ; belly granular. Brown or dark olive above, spotted 

 or marbled with darker, or with greyish variegations ; limbs with 

 dark cross bands ; beneath yellowish, uniform or marbled with

 rounded ; canthus rostralis obtuse ; loreal region concave ; nostril 

 a little nearer to the eye than to the tip of the snout ; interorbital

 distinct, hardly one third the diameter of the eye. Fingers very 

 long, dilated into very large disks, which measure more than half 

 the diameter of the eye ; inner finger with a small distal expansion, 

 as long as the second minus the distal disk ; third finger at least 

 as long as the distance between the end of the snout and the tym- 

 panum. Toes moderate, much depressed, webbed to the disks, 

 which are smaller than those of the fingers ; subarticular tubercles 

 large ; an oval, flat, inner metatarsal tubercle ; no outer tubercle ;
