FASCICULI MALATENSES 
137 
This fine new Rhacophorus is very near R. fasciatus, Blgr., from Sarawak. 
It differs in the more rounded snout, the more anterior nostril, a larger 
tympanum, and strikingly in colouration. R. shelfordi^ Blgr., also from 
Sarawak, which agrees very closely in most respects with this species and with 
R, fasciatus^ is distinguished by having the disks of the fingers considerably 
smaller than the tympanum. 
A single specimen, from Bukit Besar. 2,500 feet. 
‘ The specimen was taken in the morning, seated, a foot or two above 
the ground, on the leaf of a herbaceous plant growing in thick jungle. ‘ It was 
very sluggish, making no attempt to escape, though considerable disturbance 
had been caused by our passage in its immediate neighbourhood. The fore- 
legs were folded beneath the chest, and the hind legs were pressed close to 
the sides of the body, beneath which the feet were partially concealed ; the 
snout was somewhat depressed. The colour of the whole of the dorsal 
surface was a pale coffee, v/hich so closely resembled the shade assumed by 
many dying leaves that the frog, with its leaf-like outline in the attitude 
described, was, at first sight, mistaken for a leaf that had fallen from the trees 
above and had accidentally lodged on the plant ; Mr. Robinson, a Malay 
who accompanied us, and I were all completely deceived. At this time the 
purplish-grey of the side of the head was black, and extended in a well- 
defined band down each side. When the specimen was handled, its colour 
became darker, and mottlings of an ill-defined character, as well as the cross- 
bars on the limbs, made their appearance, as they so often do in species of 
Rhacophorus. The specimen permitted itself to be captured almost without a 
struggle, after waiting while a camera was fetched and a photograph taken. 
14. Rhacophorus nigropalmatus, Blgr. 
(PI. VI, Fig. i). 
This handsome frog, probably the very species alluded to by Wallace’' 
as the ‘ flying frog,’ was first described from Sarawak. It has since been 
rediscovered in Sumatra^ and in Upper Perak. ^ 
A female specimen was obtained at Mabek, Jalor, on the 22nd July, 
1901. Its colour in life was as follows : — ‘Dorsal surface pale grass green, 
powdered with white ; a conspicuous white mark on the dorsal surface of the 
thigh ; on the dorsal surface of the feet, the green changes gradually into 
orange ; membrane of the feet, orange marked with black ; sides of the body
