28 MR. G. A. BOULENGER ON SOME SPECIES [ Feb. 5; 
an otherwise typical R. cruciger, 34 millim. long from snout to 
vent, from Dr. Kelaart’s collection, has the flanks and the sides of 
the thighs spotted with white on a brown ground. 
Polypedates biscutiger was established by Peters for specimens 
from Rambodde, Ceylon, ‘agreeing with P. maculatus in size and 
appearance, but easily distinguished by bony nuchal prominences, 
which are especially distinct in the adult, the smaller tympanum, 
Upper surface of skulls of Rhacophorus. 
a. R. leucomystax, Darjeeling ; a’. Ditto, China ; a''. Ditto, Celebes. 6. R. ma- 
culatus, Nilgherries ; 6’. Ditto, Bombay ; 5". Ditto, Ceylon. ¢. R. eruciger, 
Ceylon. 
All the figures are taken from adult females. 
and the colour of the thighs, the hinder side of which bears large 
yellow spots on black-marbled ground.’ But these being precisely 
the characters of the true R. maculatus from India and Ceylon, it is 
clear that Peters based his comparison on the other Ceylonese form, 
R. cruciger, which he probably regarded as the typical R. maculatus, 
P. biscutiger, Ptrs., is therefore a synonym of &. maculatus, Gray.
