MR. G. A. BOULENGER ON SOME SPECIES 



[Feb. 



an otherwise typical R. criiciger, 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 specimen* 

 from Rambodde, Ceylon, "agreeing with P. mriculatus in size and 

 appearance, but easily distinguished by bony lujchal prominences, 

 which are especially "distinct in the adult, the smaller tvmpanum.

a. R. leucomysfax, Darjeeling ; a'. IJittu, Cliina ; a". Ditto, Celebes, b. R. ma- 

 culatus, Nilgherries ; b'. Ditto, Bombay ; b". Ditto, Ceylou. c. R. criiciger, 

 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 froni India and Ceylon, it is 

 clear that Peters based his comparison on the other Cevlouese form, 

 R. cruciger, which he probably regarded as the typical R. tnacnlatHs. 

 P. biscutiger, Ptrs., is therefore a synonym of R. maculatus. Gray.
