334 PROCEEDINGS OF THE CONCHOLOGICAL SOCIETY. 



work for the accomplishment of which the Society was estabUshed, 

 has we think, been most satisfactorily pursued. 



The Society has met during eleven months of the year for the 

 transaction of business. At these meetings seven papers have 

 been read, namely: — 



1. "On a proposed System of Conchological Locality 



Records," by Mr. W. Denison Roebuck. 



2. "Notes from the Isle of Wight," by Mr. C. Ashford. 



3. "Unio luteolus and its allied forms," by Prof F. M. 



Witter. 



4. "A series of Notes on the Structure of the Darts of 



H. arbustorum, H. aspersa, H. hortensis, H. 

 nemoralis, &c., and their value as a means of 

 determining species," by Mr. Chas. Ashford. 



5. "The Life-History of Helix arbustorum," by the 



President. 



6. "List of shells of the Bristol District," by Mr. J. W. 



Cundall. 



7. "List of Shells found in the Ilkley District," by 



Messrs. W. Nelson and J. W. Taylor. 



SPECIMENS EXHIBITED. 



The aggregate number of shells exhibited during the year, 

 both in regard to species and varieties as well as to individual 

 specimens, has been quite equal to that of previous years, though 

 we regret to say that in the Yorkshire exhibits there has been a 

 considerable falling off. Exhibits of Yorkshire shells have been 

 made by Mr. W. Nelson, Mr. W. D. Roebuck and the Secretary. 

 Shells from other localities have been shown by the President 

 (Mr. J. W. Taylor), Mr. W. Nelson, Mr. Robert Scharff, Mr. W. 

 Jeffery and Mr. C Ashford.
