Bemarks. — The Rana lateralis Boulenger with which Boettger com- 

 pares this species is described from Tenasserim and is related to 

 B. malaharica from Malabar and the Bombay hills. R. oMnavana 

 appears, then, to be of decided Indian affinities. 



Habitat. — There is no record of this species having been observed 

 beyond the type locality, Okinawa shima in the Riu Kiu Archipelago.
