30 Non-Marine Mollusca of Lincolnshire. 
The following List includes 10g species, 133 varieties and 3 
monstrosities. A good list when we consider that of the 170 
species, in the catalogue adopted, 26 species are either extinct or 
introduced. Only 144 species are left for comparison. 
There are several species which may be reasonably expected to 
turn up and I hope that attention will be directed to this end. 
I take this opportunity of expressing my great indebtedness 
to Mr. J. W. Taylor for his kindness in verifying the 
identification of species and many varieties. This gives equal 
value to all the new records here published ; [also desire to thank 
the numerous workers who have kindly assisted in so far working 
out the Mollusca of the County. 
I shall be very pleased to receive further collections 
of Mollusca, together with locality, soil, and other notes, 
especially from those divisions for which we have few records.
