The " eye supports " differ from ttose of true Paludina, fide 

 Benson, J. A. S. B., 1855. Mons. Bouvier has also sent me ten 

 specimens, exactly resembling Canton ones, as from " Cochin- 

 China." I fear he has been misled by his correspondent ?

Very close to PI. X, figs. 15 to 17 of Kobelt's Fauna Japo-

 specimens can be easily distinguished from the Japanese form 

 by the subglobose, instead of angulate periphery.
