Insects. 1787 



it in slow streams in Hertfordshire for the last three years successively, but nowhere 

 else, and have never met with any specimens in the same locality that are intermediate 

 between it and the strongly banded Pal. achatina, but, on the contrary, all the other 

 specimens I have taken in that neighbourhood, and associated with it, are the most 

 strongly banded I have ever seen. 



I have a series of Pal. achatina, taken in the neighbourhood of Newbury, Berks, 

 varying from strongly banded to very faint, also from other localities, but, however pale 

 or faint, yet the bands are distinctly visible both inside and out on holding the speci- 

 mens to the light: this is not the case with the shell under consideration, as in all the 

 specimens I have taken, varying in size from one-eighth, to one inch and a quarter, 

 not a vestige of banding is discernible. As this shell is so very distinct in appearance 

 from the two described species of British Paludina, viz., Pal. vivipara and Pal. acha- 

 tina, both of which have hitherto been described, figured, and regarded as banded 

 shells, I propose, until decided whether it be a distinct species or not, naming it Palu- 

 dina achatina, var. efasciata, which name can stand as specific, should it hereafter 

 prove to be a species. — John Pickering ; 117, Lower Thames Street, May 17, 1847.
