a few narrow dark cross-streaks on the limbs; white beneath. 

 Length 60 mm. 



Closely allied with Rh.javanus, from which it is distinguished 

 by the shorter hind limbs and the coloration; from RJi. poe- 

 cilonotus it can be distinguished by the more extensively 

 webbed fingers.

 1600 m. !, and Sinlak Deras! in Kurintji, E. Jacobson leg.).
