Vomerine teeth in short transverse or feebly obHque series or 

 small feeble groups on a level with the posterior borders of the 

 choanae or just behind them, the distance between the two series 

 equal to or a little less than the length of one of them. Tongue 

 with a long pointed papilla in the middle. 



Head rather strongly depressed, as long as broad or a little 

 l)roader than long; snout rounded, feebly projecting beyond the 

 mouth, as long as or a little shorter than the eye ; canthus 

 rostralis ver}' obtuse or indistinct ; loreal region oblique, concave ; 

 nostril equidistant from the e^-e and from the tip of the snout ; 

 distance between the nostrils a little greater than the inter- 

 orbital width, which is equal to or a little less than that of the 

 upper eyelid ; tympanum very distinct, i to :^ the diameter of the 

 eye, i to 3 times its distance from the latter. 



Fingers moderately long, the tips dilated into rather large 

 discs, which are a little broader than long and with a groove in 

 front, separating the upper from the lower surface ; first finger 

 shorter than the second, third a little longer than the snout ; sub- 

 articular tubercles moderately large, not very prominent. 



Hind limb long ; the tibio-tarsal articulation reaches the tip 

 of the snout or beyond, rareh' between the eye and the tip of the 

 snout, the heels strongly overlap when the limbs are folded at 

 right angles to the body ; tibia 4 to 5 times as long as broad, i| to 

 if times in length from snout to vent, as long as or a little longer 

 or a little shorter than the fore limb, slightly longer than the foot. 

 Toes rather long, depressed, and dilated at the end like the 

 fingers, t| webbed or the web reduced to a mere rudiment, and not 

 penetrating or scarcely penetrating between the outer metatarsals ; 

 subarticular tubercles rather small, feebly prominent ; no tarsal 

 fold; inner metatarsal tubercle elliptic, feebly prominent, h to f 

 the length of the mner toe ; no outer tubercle. 



Skin of back with short longitudinal glandular folds ; sides 

 granulate, with flat warts ; a strong grandular fold from the eye to 

 the shoulder. Lower parts smooth, or posterior part of belly 

 feebly granulate. 



Olive or brownish above, mottled with darker ; a more or 

 less distinct subtriangular dark spot between the eyes, often limited 

 in front by a Hght cross-bar ; a black streak along the canthus 

 rostralis and a black temporal spot ; a light vertebral band some- 

 times present; limbs with dark cross-bars. Lower parts white, 

 uniform or spotted with brown, sometimes brown dotted with white. 



Males without secondary sexual characters. 



Skeleton as in R. heddomii. 



The tadpole referred to this species by Annandale is pretty 

 normal in shape, the tail about if times as long as the body and 

 ending in a blunt point ; but the mouth-disc is very remark- 

 able, without horny teeth ; the upper lip forms a crescentic mem- 

 brane which can be closed down over the mouth, the lower is 

 divided into three lobes, and there is a large, rounded lateral 

 lobe ; all fringed with pointed papillae ; papillae are scattered on
