NON-MARINE MOLLUSCA OF 
LINCOLNSHIRE. 
C. S. Carrer, M.C:S. 
Hon. Curator, Louth Ant. and Nat. Soc. 
Since the publication, in 1887, of Mr. W. Dennison Roebuck’s 
admirable paper ‘“ Materials towards a List of the Land and 
Freshwater Mollusca of Lincolnshire,’ which appeared in the 
Naturalist for that year, much good work has been accomplished 
by a number of enthusiastic collectors. Except for the very 
useful List compiled by Mr. H. Wallis Kew, published in the same 
Journal for 1902, and the various scattered notes, which have 
also from time to time appeared there very little, comparatively, 
is known of the amount of good work done during the last 
eighteen years. 
The present list has been compiled in compliance with 
requests frequently made to me, to record, as far as space will 
allow, what has been done, and therefore what _ still 
remains to be accomplished. It is hoped that the enthusiasm of 
the past will not in any degree be diminished, but rather 
stimulated by successes to greater activity. 
It is with regret that I have not been able to incorporate 
the whole of the records of Mr. Roebuck’s great collection of 
Lincolnshire Non-Marine Mollusca. Its owner is at present 
abroad, and neither notes nor specimens are accessible, 
and the space at our disposal is also insufficient for doing 
justice to Mr. Roebuck’s work asa Malacologist. I learn, however, 
that he contemplates publishing a list on his return, 
so we may all look forward with expectancy for the result of 
more than twenty years work in our County. 
The classification, and nomenclature adopted here is 
that published by the Conchological Society in 1904, except in 
some few cases amongst the slugs, where Mr. Taylor’s Monograph 
has been followed. 
When a species is common and generally distributed, only 
the first known record, and the Natural History Divisions of the 
County, for which it has actually been recorded, have been given.
