906 MR. 8. 8S. FLOWER ON THE REPTILES AND [Dec. 1, 
Cantor gives Penang, Singapore, and the Malay Peninsula as 
localities, and says ‘‘although it inhabits Singapore ..... it 
appears not to occur in the valleys of Penang, but to affect the 
hills, at an elevation of more than 2000 ft.” Stoliczka mentions 
it as being “not uncommon in Penang.” I found this species 
very common both in Penang and Singapore, but, contrary to 
Cantor’s experience, I found it at Penang at almost the sea-level 
(20 ft.), though it was certainly more numerous on the hills. It 
is a cheerful little frog of most graceful build. It comes out from 
its hiding-places shortly before sunset, and remains abroad all 
night; the males are easily found as they sit on shrubs or trees or 
on the edges of the rainwater-butts under the verandahs of the 
houses, and from time to time utter a single rather musical short 
croak. In March and April they can be found both by day and 
night in copuld in ponds. Cantor mentions the power of changing 
its colours this species possesses. It changes both its colour and 
markings very rapidly and frequently, but dark bands across the 
legs can always be more or less distinguished ; the lower parts are 
some shade or other of buff, but the principal variations of the 
upper parts are as follows :— 
(i.) pale bronze, uniform ; 
(ii.) pale bronze, with four longitudinal dark brown or 
black lines ; 
(iii.) a bright yellowish-bronze, almost orange, uniform ; 
(iv.) reddish-brown, almost chocolate, mottled with darker ; 
(v.) pale brownish-green or olive, with irregular dark 
spots ; 
(vi.) callowikt isan mottled with darker or brown. 
The Rhacophorus mentioned by Stoliczka (J. A. 8. B. 1873, 
p- 112) as a separate species, Polypedates quadrilineatus, from 
Penang, is not even a true variety, as the dark lines appear 
conspicuously and disappear entirely in the same individual. If 
killed with or without the lines visible they remain so in spirit. 
In Singapore at different times I noticed many young frogs which 
had just left the water all of which had the dark lines visible ; 
these disappear as the animal grows, only to reappear temporarily 
in the adult. 
The females are considerably larger than the males ; the largest 
male I caught was 48 mm. from snout to vent, and the largest 
female 68 mm. from snout to vent.

Tadpole. In January, February, March, and April, 1896, I 
found the tadpoles of this species in several small ponds and in 
rainwater-butts about Singapore; and was able to collect a large 
series for the British Museum.
