Exhibits : 



On behalf of Dr. ScharfF were shown the examples of Helix nemoralis 

 presented to the Society's collection, with a note that Mr. R. D. Darbishire 

 believes that the richly calcareous quality of the soil at Roundstone may have 

 tended to the formation of the lieavy shells which are there found, that he 

 (Dr. Scharff) had, however, collected recent specimens living on the same 

 calcareous soil which exhibited no thickening whatever of the shell, so that 

 this reason appeared to him to be insufficient to account for the production 

 of the heaviness of the shell. Dr. Scharff in his note asked for opinions on 

 the point. He mentioned also that Mr. Latham, of Manchester, ground down 

 a number of these shells and found that after eliminating the sand, etc. , there 

 still remained a very large quantity of pure carljonate of lime (he forgets the 

 exact figure) soluble in muriatic acid (see Proc. Lit. & Phil. Soc. Manchester, 

 vol. 4, 1865). 



On behalf of Mr. Robert Cairns were exhibited a var. of Biilinins 

 obsamis and the \2S. fttlva of Helix cnperata, both from Clifton, B. acutiis 

 var. injlata, from Peel, Isle of Man, and Planorbis contortics var. alba, from 

 Marple, Cheshire,
