rior borders. Head as long as broad; snout obtusely pointed, 

 feebly projecting, as long as the upper eyelid, much deeper 

 than long; canthus rostralis very distinct; loreal region dis- 

 tinctly oblique, concave; nostril a little nearer to tip of snout 

 than to eye ; interorbital space narrower than the upper eyelid ; 

 tympanum very distinct, 4 / 5 the width of the eye. Disks of 

 fingers and toes very small, not more than about 1 / 5 the dia- 

 meter of the tympanum ; first finger much longer than second, 

 which is longer than fourth ; third toe as long as fifth ; toes 

 2 / 3 webbed, two phalanges of fourth, and one phalanx of the 

 other ones being free; subarticular tubercles very prominent; 

 a distinct, oval inner and a very small, round outer metatarsal 

 tubercle; the heel reaches the nostril; tibia about 1 / i the length 

 of head and body. 



Skin finely granulate above ; a very narrow, but prominent 

 glandular dorsolateral fold; some narrow oblique folds on the 

 back; lower parts smooth; posterior surfaces of thighs granular. 

 From snout to vent 63 mm. 



Dark brown above; temporal region and cross-bands on 

 the limbs black. Lower parts lighter, uniform. 



Male with internal vocal sacs and humeral glands. 



I examined the specimen described by Werner and Roux 

 and now preserved in the Basle museum. The species is nearly 

 related to R. temporalis from Malabar, but distinguished by 

 the position of the vomerine teeth, and the shorter web 

 between the toes. From R. nicobariensis it may be distinguished 

 by the broader head and the narrower interorbital space. 



Habitat: Sumatra (Laut tador !).
