NOTES ON THE LAND AND FRESH-WATER MOL- 
LUSCA OF GREENOCK AND SURROUNDING 
DISTRICT. 
: BY THOMAS SCOTT. 
[Read 29th December, 1885.) 
NINE years ago, when the British Association held 
its meetings in Glasgow (in 1876), a number of very use- 
ful lists of species belonging to various groups, both of 
animals and plants, were prepared; and these form 
no inconsiderable part of the Fauna and Flora of 
the West of Scotland, a book which is very useful 
to all students of Natural History for reference. 
Among these lists is one of the Land and Fresh- 
water Mollusca, which includes all the species known 
to its compiler as occurring in the West of Scotland 
at that time. 
| Through the zeal and energy of various workers, 
our knowledge of the Natural History of the West 
of Scotland has been considerably increased during 
these nine years; and one of the branches which 
have to some extent been successfully worked up is 
that of the Land and Fresh-water Mollusca. Not 
only have new stations been found for the species 
already known to occur, but several species and 
varieties have been added to the list of those pre- 
viously recorded; and no doubt, as the study of 
this branch becomes more widely and thoroughly 
carried out, other additions will yet be made. 
Accordingly, with the progress made in other 
branches of Natural History, it will possibly be found 
that ere long the second edition of the Fauna and 
Flora, referred to in the preface to the first, will be 
much needed; and it is to be hoped that this will. 
by-and-by be an accomplished fact. Not only will a
