rostralis angular, straight; loreal region nearly vertical, concave; 

 nostril equidistant from eye and tip of the snout, or nearer to 

 the latter; interorbital space as broad as or a little narrower or 

 a little broader than the upper eyelid; tympanum distinct, '"/g to 

 equal to the width of the eye. Disks of fingers small, of toes as 

 large or slightly larger; first finger extending beyond second, 

 which is a little shorter than fourth ; toes entirely or nearly 

 entirely webbed, the web reaching all disks or the two distal 

 phalanges and sometimes part of the next phalanx of fourth toe 

 are free; outer metatarsals separated nearly to the base; sub- 

 articular tubercles well developed; a distinct, oblong inner, and 

 a smaller, round outer metatarsal tubercle; no tarsal fold; the heel 

 reaches to between the anterior border of the eye and the 

 tip of the snout or beyond ; tibia about ^j^ to ^/g the length 

 of head and body; when the hind limbs are folded at right 

 angles to the body, the heels are strongly overlapping. 



Smooth or finely granulate above; a narrow dorsolateral 

 fold and a glandular fold from below the eye to the shoulder, 

 sometimes followed by one or two glandules; sometimes a 

 few scattered warts on back and sides; smooth below. 



Greyish, brownish, pink, or blackish above, sometimes marbled 

 with darker, the warts usually dark; loreal region or a streak 

 below the canthus rostralis often dark brown or black; a 

 more or less distinct dark temporal spot, sometimes (especially 

 in the young) continued into a black streak along the side 

 of the body, bordered above by the often light-coloured dorso- 

 lateral fold; sides rarely reticulated with blackish; tympanum 

 usually reddish brown ; a narrow light vertebral line, and another 

 light line along the tibia may be present; often a white streak 

 along the upper lip, continued to the shoulder; limbs with 

 dark cross-bars; beneath white, often powdered or reticulated

 a pair of dark spots on the breast and an oblique dark bar 

 on the shoulders. From snout to vent no mm.
