Habitat. Hills of Central Ceylon. 



This frog is closely allied to R. limnocharis, but I have no 

 hesitation in regarding it as entitled to specific rank. It is easily 

 distinguished by a combination of characters : first and second 

 fingers equal or nearly so, diameter of tympanum not greater than 

 interorbital width, outer metatarsal tubercle absent or very in- 

 distinct, inner metatarsal tubercle usually smaller.

 Rana gracilis, part., Bouleng., Cat. Batr. Ecaiid. p. 28 (1882). 



Vomerine teeth in rather strong oblique series between and 

 extending posteriorly beyond the choanae. 



Head as long as broad or slightl}^ longer than broad, moder- 

 ately depressed ; snout rounded or pointed, as long as or a little 

 longer than the eye, projecting more or less beyond the mouth ; 

 canthus rostralis very obtuse ; loreal region oblique, concave ; 

 nostril usually a little nearer the end of the snout than the eye ; 

 the distance between the nostrils greater than the interorbital 

 width, which is less than that of the upper eyelid ; tympanum very 

 distinct, I to I the diameter of the eye and i| to i| times its 

 distance from the latter. 



Fingers obtusely pointed, first longer than the second, third 

 as long as or a little longer than ttie snout ; subarticular tubercles 

 well developed and very prominent. 



Hind limb very long, the tibio-tarsal articulation reaching the 

 tip of the snout or a little beyond, the heels strongly overlapping 

 when the limbs are folded at right angles to the body ; tibia 4 

 to 4^ times as long as broad, if to slightly less than 2 times in 

 length from snout to vent, shorter than the foot, a little longer or 

 a little shorter than the fore limb. Toes rather pointed, very 

 slender, barely ^ webbed, the web not reaching the second 

 phalanx ; outer metatarsals separated nearly to the base ; sub- 

 articular tubercles rather small, moderately prominent ; tarsal 

 fold absent or reduced to the distal half ; inner metatarsal tu- 

 bercle strong, eUiptic, compressed, i to f the length of the inner 

 toe ; a rather indistinct outer metatarsal tubercle. 



Back with elongate glandular warts or interrupted longitudi-
