CENSUS OF LINCOLNSHIRE LAND 
AND FRESHWATER MOLLUSCA 
to end of 1908. 
W. Denisen Rorsuck, F.L.S., 
President L.N.U. 
It is proposed--with the assistance of the Lincolnshire 
conchologists and all interested in the subject—to prepare for 
publication a new and detailed Catalogue of the Land and 
Freshwater Mollusca of the County, but before this can be done, 
there are numerous blanks to be filled up. 
The districts into which the county is divided are 34 in 
number—as set forth by the Rev. E. Adrian Woodruffe- Peacock, 
with coloured map, in “The Naturalist” for October 1895, 
pp. 289—301. 
I give them in the order in which they have been least 
worked for Mollusca, as follows :—

recorded. recorded.

The whole number of species recorded for the county is 
116—of which 111 are known for North Lincolnshire, and 100 
for South. 
‘The mass of material available is the result of the labours of | 
numerous conchologists for many years, and has been brought 
together by my friends Mr. C. S, Carter and Rev. E. Adrian 
Woodruffe-Peacock, as well as myself, from our numerous and
