BATRACBIANS OF THE MALAY PENINSULA. 393 



Discovered by Mr. L. Wray on the Larut Hills, Perak, at 3,000 ft. 

 elevation, and so far known only from this locality. They inhabit 

 holes in trees which contain rain water. When croaking they lie in- 

 flated on the surface of the water with limbs extended after the manner 

 of Callula pulchra. In April 1900 I procurod three examples on the 

 Larut Hills. Two were captured in holes in trees, at about 3,500 ft. 

 elevation. The colour of these two was dark blackish brown. The 

 third specimen I took from a crevice in a rockery at the " Cottage," 

 within a yard of a postmarked " 4,513 feet above M. S. L." Tho 

 colouring of this example was quite different and was in life as follows : 

 Pale yellowish clay colour, becoming yellower on the insides of the 

 thighs. Tympanum, and a bar across the head between the eyes, grey ; 

 back faintly mottled with gray. Three greyish black bars across the 

 thighs, two on the second, and three on the third joint of the hind 

 limbs. Beneath, pale drab or stone-colour, strongly tinged with pink- 

 ish. Chin, and a line down centre of throat blackish. 



An old specimen given me by Mr. Wray, caught at the same 

 time as the type, has faded in spirit to a brownish red. 



The croak of this frog is described by Mr. Wray as u loud, flute-like 

 and musical."

The only locality in which I have found this curious toad is the- 

 little Sungei Buloh River in Selangor, on the banks of which, above 

 the reach of tidal influence, the}' are not uncommon. I obtained four 

 of them — an adult male and three smaller specimens — while on a trip 

 up the river in 1898. Unfortunately all except the large specimen 

 were subsequently lost. In October 1899 Mr. A. Hale, whom I had 

 asked to try and get me more of these toads, procured me a very large 

 female specimen. He caught three or four more, but these again 

 were lost, through the overturning of a boat, I think. 



The habits of this toad are 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 fset 

 would lead one to suspect, powerful swimmers. When the rnaie* 

 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
