Java, Borneo, Sumatra. Discovered by Mr. A. L.Butler on the 

 banks of the little Sungei Buloh Eiver in Selangor, above the 

 reach of tidal influence, where this curious toad is not uncommon. 

 Mr. Butler describes the habits as aquatic and arboreal. " They are 

 usually found sitting on branches overhanging the water, into 

 which they dive when disturbed. They are, as their fully webbed 

 hind feet would lead one to suspect, powerful swimmers. When 

 the males are croaking the blackish pouch under the throat is 

 inflated to the size of a pigeon's egg. Their croak is generally 

 uttered three or four times in very I'apid succession and then 

 followed by an interval of silence."'
