MELANIlDiE, 281 



93. Melania [Plotia] datura. 



Melania datura, Bohrn, F. Zool. S. 1S58, CeyloUy long. 21, diam. 11 mil. ; 

 Con. Indica, pi. 73, fig. 10. 



M. Brot unites, as a variety, the forms from Ceylon figured 

 in the Con. Indica, pi. 110, fig. 7 as M. scabra, var. spinulosa 

 and fig. 10, as M. accmthica, Dohrn ; this is, I think, more than 

 doubtful, as also, I consider, is his statement that the three forms 

 are found together ; this is quite opposed to all I know on the 

 subject, and it would be desirable if the Professor would give 

 his authority for the statement.
