118 Address to the Lincolnshive Naturalists’ Union. 
There are perhaps one or two species of the genus Vertigo to 
be found, but the shells are exceedingly minute and need special 
skilled knowledge for their successful search. 
Succinea oblonga might possibly be found, as also might 
Acicula lineata, another very minute shell. Planorbis glabey is one 
which might possibly occur, and Pisidium cinereum will very likely 
occur some time. 
There are other methods in which the new list may be 
helped. We require notes on environment, on food, on soil- 
preferences, on species-associations, in short, on anything which 
tends to give life to our dry bones. 
For our introductory chapters we need notes on observers, 
on the work they have done, on their history and career. We 
should particularly like help from photographers—views of 
characteristic shell-localities, snapshots of the investigators, all 
which would help to find material for illustrations to accompany 
the work. 
So may we hope to put together an account of our Lincoln- 
shire snails that will be of some value and use to future 
investigators and be in some degree worthy of the county of 
Newton, of Banks, and of Lister. 
CHECK-LIST OF LINCOLNSHIRE PLANTS. 
4 
I much regret to say after this Check-List was published 
and issued to the Union, it was discovered that three species had 
been omitted through the sticking of the sheets of the original 
manuscript. Would members kindly add the following three 
records to their copies of the Check-List ? 
COCHLEARIA ARMORACIA, L. 1865, Britten. —1, 4, 5,7, 8. 
NYMPHOIDES PELTATUM, Rendle & Britten. 1895, Craster. +13, 15. 
VIOLA ARVENSIS, Murr. 1851, Watson. -+all. 
Many new divisional specimens and records have already been 
received, and before the end of this season much _ further 
additional matter may be expected, but all this material must 
wait for the full ‘‘ Flora of Lincolnshire.”
