Geographical Distyibution. The species was described from Java and Dr. van 
Kanipen, who has been kind enough to examine the large specimen from vSinggora 
figured on plate tells me it cannot be distinguished from Javanese examples. 
From Mr. Boulenger's notes it appears that R. cancrivora occurs all over the Malay- 
Archipelago as far east as the Celebes. If I am right in regarding R. vittigera , VVieg- 
mann, as a synonym, it also occurs in South China and the Philippines. There is a 
specimen from Mandalay in t le British Museum, but I have not seen any from 
Burma myself. Most of the specimens in the Indian Museum are from the vSiamese 
peninsular provinces of Sunkla (Singgora) and Patani. 
In the country round the Tale Sap or Inland Sea of Singgora R. cancrivora is, in 
moderately damp places, by far the commonest frog. It is fond of sitting at the edge 
of ponds or ditches, and sometimes at that of the lake itself, and when disturbed 
dives into the water and buries itself in the mud at the bottom. Near Singgora it 
frequents ditches of brackish water and I saw a half-grown frog, which I subsequently 
captured, leaping into the sea from a rock at the mouth of the lake. 
The following specimens are preserved in the Indian Museum. I have also ex- 
amined others from the same localities that have now been distributed to various 
correspondents, as well as 17 specimens from North Borneo that the authorities of 
the Sarawak Museum have been kind enough to lend me, and several from Siam.
