116 Address to the Lincolnshive Naturalists’ Union. 
As far as our own particular line of research is concerned, a 
reference collection of the shells upon which my forthcoming list 
is to be founded, is being put together and later on a display 
collection of good examples of each species and well-marked 
variety will be formed. 
Not very much work was done in 1907 except that Mr. John 
F. Musham, F.£.s., who has now worked the county with great 
assiduity and vigour during the past year or two, printed for 
private circulation a list of his captures, giving localities for 89 
species and numerous named varieties—and a year later he 
supplemented it by a list of additions, concerning 32 species. 
In 1907, Mr. Vernon Howard found the reversed or 
dextrorse monstrosity of the common Clausilia bidentata in the 
Louth district, and in 1908 Mr. Beetlestone found the sinistrorse 
or reversed monstrosity of Helix nemovalis near Market Rasen. 
In our Transactions for last year (1908), I published a Census 
of the distribution of our Land and Freshwater Mollusca, showing 
in tabular columns the districts for which each species has been 
recorded. Copies of this I shall be happy to give to anyone— 
conchologist or not—who will assist us in securing material to 
fill up the blanks in our knowledge. 
There are various other people who have worked at our 
subject, and have not published. Mr. Henry Preston, of 
Grantham, our geological ex-president, has worked for some 
years along with Messrs. Hawkins, Stow and Worsdale, the 
Grantham Museum displaying some of the results of their 
labours; and Miss Florence H. Woolward, of Belton, has also 
worked with the Grantham group of investigators. 
The Rev. W. W. Mason, in the course of his botanical 
perambulations, never forgets his conchological friends and their 
insatiable thirst for detailed information. 
In the north of the county, Mr. John Beaulah, of Raven- 
thorpe, near Brigg, is a collector of old standing, whose stores 
of knowledge we hope before long to avail ourselves of. 
The recent lamented death of Mr. Alfred Reynolds, of 
Owston Ferry, has deprived us of a keen and active worker.
