line; in bimaculatus they make an obtuse angle. The 

 external metatarsals are completely separated in rein- 

 wardti, in bimaculatus not completely. 



Tadpoles taken on Fraser's Hill and bred out by me 

 agree entirely with van Kampen's description of the tad- 

 pole of reinwardti (Nat. Tijd. Ned. Ind., LXIX., 1909, 

 p. 43). 



The colouration of R. bimaculatus in life shews 

 considerable variation, the upper parts ranging through 

 various shades of green, grey, pink or brown, usually 

 uniform but sometimes with an indistinct dark) (upon 

 the back. Below dull yellow the membrane between the 

 fingers yellow, between the toes red or orange, this 

 colour sometimes including the upper arm, flanks and 

 a band along the thighs. Very young specimens are 

 light brownish-green above, with a white throat and belly 

 and yellow limbs. 



R. reinwardti appears to have accomodated itself to 

 more lowland conditions, thriving at Buitenzorg, altitude 

 250 m., while R. bimaculatus as far as the Malay Peninsula 

 and Siam is concerned has not been found below 700 m.

A fine series of 16 specimens of this little tree-frog, 

 hitherto known only from a single example. (Nos. 5970 

 and 6007 to 6021), One was taken by Mr. Chasen at Kuala 

 Teku on a broad leaf overhanging the water, the remainder 

 are from Camp Padang. The type was obtained by Mr. 

 Robinson on Gunong Tahan at 1,000 metres. 



The series agrees well with the description. The tibio- 

 tarsal articulation may reach to the anterior border of the 

 eye. The tympanum varies in distinctness, and is always 

 smaller than the disc of the third finger. The skin of the 

 back is smooth in some, finely shagreened in others. 



As is common with many species of Philautus the 

 colour is variable. About half the scries shew the dark 

 patch on the back, more or less as figured in the description 

 of the type. In others the back is uniformly but coarsely 

 speckled with black all over. Some have no dark bars to 

 the Ihnbs. Greyish olive is the predominating colour above, 

 except in one example which is reddish brown. 



The example from Kuala Teku (No. 5970) is pale grey 

 above (under the glass dark grey finely vermiculated with 

 buff), and with a broad irregular buff band along either 

 side of the back. This specimen, the largest, measures 36 

 mm^ from snout to vent. 



Several of the females contain ripe ova, the eggs being 

 large, few and pigmented. Diameter 2 mm;
