[Very young specimens of this Toad were extremely common along 

 the sandy banks in certain parts of the Tahan River : they harmonised 

 with their surroundings in a most wonderful manner, so that it was 

 almost impossible to detect them, except when in motion.

[Though only a single specimen of this Frog was obtained, it was 

 probably anything but rare, as its peculiar note, more like that 

 of an insect than a batrachian, was constantly heard in the evening after 

 rain. The species lives in small holes in tree trunks, often at a 

 considerable height from the ground, and is to be secured by dropping 

 salt into the water with which the hole is generally filled, when the 

 Frog will rise to the surface. — H. C. R.]

The longer hind limbs distinguish this species, previously known 

 only from Borneo, from R. chalcmwta, Schleg. Males are much 

 smaller than females and have the tympanum larger in proportion to 

 the size of the digital disks.
