BIBLIOGRAPHY OF THE NON-MARINE MOLLUSCA 

 OF LANCASHIRE. 



By J. WILFRID JACKSON. 



(Read before the Society, November 14th, 1906). 



Some time ago, with a view to working up the Non-Marine 

 MoUuscan Fauna of Lancashire, I commenced to hunt out records 

 of previous work done in the county, and was astonished to find 

 so many references scattered up and down in various pubUcations 

 and transactions of Societies, many of which go back almost to the 

 commencement of last century. Finding so many useful notes in 

 little-known publications, it occurred to me that a bibliography of 

 them would not be out of place in the pages of our fournal, and 

 furthermore might prove useful to those who, like myself, are interested 

 in the conchological literature of the county. 



Though somewhat startled at the outset at what appeared a for- 

 midable task, I persevered with the work, and, thanks to numerous 

 friends, I have been able to compile a list, brought up to the end of 

 1906, which may be looked upon as fairly satisfactory and toleral)ly 

 complete. The work entailed has been considerable, owing to the 

 records being so scattered, and has necessitated the consultation of 

 works both in public and private libraries, particularly that of my 

 friend, Mr. Alfred Leicester, whose fine collection of local con- 

 chological literature has proved of the greatest service. 



It is a matter for regret that some of the earlier Manchester 

 collectors, such as F, Kenderdine, T. Glover, T. Peace, T. Kelsall, 

 8. Brockbank, T. Morley, and others, did not leave behind them 

 published records of their discoveries. One has only to turn to Miss 

 Maria Glover's notes on her father's collection (y. Conch., vol. ii, pp. 

 368-372) to show that the conchologists of his day were quite as 

 active and enthusiastic as those of the present. 



The first published record I can find is Kenyon's Preston list, 

 1829. Contemporary with him was Dr. Gilbertson, of Preston, who 

 first discovered Vertigo alpestris in this country. Unfortunately he 

 did not live to publish his MSS., which at his death went to the 

 British Museum, along with his collection. These MSS. were 

 evidently of great importance ; Gray, Forbes and Hanley, and Gwyn 

 Jeffreys all quoting from them. Kenyon and Gilbertson, therefore, 

 might be looked upon as the pioneers of Lancashire non-marine 

 conchology.
