PROCEEDINGS of the CONCHOLOGICAL SOCIETY. 



Meeting, 



HELD JANUARY 25TH, 1883. 



Mr. J. W. Taylor was voted to the Chair. Correspondence 

 was submitted from the President, Dr. W. H. Evans, and 

 Messrs. W. Jeffery, J. W. Cundall, R. Scharff and E. Collier. 

 Mr. Collier wrote: — "In exchanging shells I often receive 

 Pisidiwn and Splmriiim with both valves separated, and in 

 such cases the right ones cannot well be put together. The 

 method I adopt for my own cabinet is as follows: — Having 

 placed my shells in a basin, I pour over them water sufficiently 

 warm to cause the shell to open, and after extracting the animal 

 (even in such species as Pisidhifu pusillum it can easily be done) 

 screw up the shells singly in small pieces of thin tissue paper, 

 so that when dry, which will not take more than two or three 

 days, the valves will be closed as in life. I have found this 

 plan to answer perfectly even for S. corneum and 6". ovale. 

 S. rivicola, I find, answer best to be tied up with thread." 



NEW MEMBER. 



Mr. J. Morgan of Sutton, was elected a member of this 

 Society. 



PAPER READ. 



A Paper on the Land Shells of Gibraltar, by Dr. Kobelt 

 of Schwanheim, translated from the German for the Society by 

 Mr. R. Scharff. The thanks of the meeting were voted to Dr. 

 Kobelt for his valuable communication, and to Mr. Scharff for 

 the translation.
