On behalf of Mr. J. D. Butterell, a specimen of Testacella

 that this species appears not uncommonly in gardens at Beverley. 

 The Chairman observed that specimens of this Testacella had 

 occasionally been obtained by Mr. J. Emmett from the nurseries 

 at Boston Spa ; also that Mr. Shrubsole of Chester had written 

 him stating that this species occurs freely in a lane near that 

 town, and that a gardener there keeps them on purpose to kill 

 worms in his Fernery. Several specimens were shown oi Helix

 cellarius and Z. niiidulus from Pontefract Lane near Leeds ; and

 pusillum from Middleton, on behalf of Mr. D. Barnfather.

 varieties, including var. cerma from the Avon canal, Freshford, 

 near Bath. This is the first occasion on which this variety has 

 been recorded as British. Mr. Taylor further showed a series 

 of shells from Cantley and Doncaster ; and Limncea peregra var. 

 maritima from Scarborough. A number of shells were shown 

 for Mr. T. H. Easterfield, including Limncea auricularia var.
