■ 1) For practical reasons the division in subgenera has not been taken in 

 consideration in this synopsis. It differs in this point from the synoptic tables 

 of the South Asian, Papuan, Melanesian and Australian species of Rana, which 

 Boulenger (Rec. Ind. Mus., XX, 1920) has given and which may be compared 

 with my synopsis.
