Head as long as broad or a little broader than long, moderately or 

 rather strongly depressed; snout rounded, feebly projecting beyond 

 the mouth, as long as the eye or slightly longer or shorter; canthus 

 rostralis obtuse; loreal region oblique, concave; nostril equidistant 

 from the eye and from the tip of the snout or a little nearer the former; 

 distance between the nostrils greater than the interorbital width, 

 which is about | that of the upper eyelid or a little more; tympanum 

 very distinct, f to once the diameter of the eye in females, 1 to 1^ 

 times in males, close to the latter or separated from it by a space not 

 exceeding | its diameter. 



Fingers moderate or rather long, usually pointed, sometimes rather 

 obtuse, first as long as or a little longer than the second, third longer 

 than the snout; a narrow dorsal fold sometimes present along the 

 sides of the fingers; subarticular tubercles moderate or rather small, 

 moderately prominent. 



Hind limb moderately long, the tibio-tarsal articulation reaching 

 the eye or between the eye and the tip of the snout, the heels over- 

 lapping when the limbs are folded at right angles to the body; tibia 

 3 to 4 times as long as broad, if to 2j times in length from snout to 

 vent, shorter than the fore limb, as long as or shorter than the foot. 

 Toes obtuse or rather pointed, f to nearly entirely webbed, 1 or 2 

 phalanges of fourth free; outer metatarsals separated nearly to the 

 base; subarticular tubercles rather small, feebly prominent; tarsal 

 fold absent or very feeble; inner metatarsal tubercle elliptic, feebly 

 prominent, t to f the length of the inner toe; no outer tubercle. 



Skin smooth or granular above, on back with numerous small warts ; 

 a glandular dorso-lateral fold, usually narrow and prominent, some- 

 times broken up or very indistinct, from above the tympanum to the 

 sacral region or, rarely, a little beyond; the distance between the 

 folds 4| to 5| times in the length from snout to vent. 



Head and anterior part of body usually bright green, and posterior 

 part of body and limbs olive or brown; body sometimes entirely 

 green or brown; back usually with more or less numerous black spots 

 or marblings; tympanum often reddish brown; dark cross-bands on

 large pad on the inner side of the first finger. 



Skeleton as in R. esculenta. Nasal bones in contact or narrowly 

 separated from each other, sometimes in contact with the frontoparie- 

 tals. No character of any importance distinguishes the tadpole from 

 that of R. catesbiana, and the eggs are likewise very small.
