less than seventeen notes and articles from Mr. Kew, dealing 
with the Lincolnshire mollusca in no dry-as-dust manner, but 
with the addition of details that betokened the alert mind as well 
as the observant eye. 
It is of interest to recall that it was the accidental finding of a 
freshwater cockle attached to the leg of a water-beetle at West 
Barkwith in August 1888, that set Mr. Kew collecting particulars 
of cases of similar significance, which ultimately—in 1893— 
resulted in the publication of his excellent book on ‘ The 
Dispersal of Shells.” 
The species which is most closely identified with Mr. Kew 
is the discovery of Clausilia volphii in the postglacial ravines near 
Louth—a discovery which was made in 1887. The species was 
subsequently identified at Grantham by Messrs. Hawkins and 
Worsdale, and there is no doubt ‘that Mr. Hawkins had taken it 
many years before without regarding it as more than a strongly- 
marked variety of one of the other species of the genus—but 
that he did discriminate it is not to be doubted. The species is 
one of what we may consider the disappearing ones, and the 
Lincolnshire localities are a great distance from the other known 
British stations, Northamptonshire being the nearest. 
In 1886, the Rev. Canon W. W. Fowler, our entomological 
ex-President, announced the discovery and at the same time the 
extinction, by railway extension, of Limnea glabva near Lincoln, 
a species which ought certainly—judging by its Yorkshire distri- 
bution—to be found in the north of our county. 
I now come to my own connection with Lincolnshire 
Conchology. In 1883, I collected on the edge of the Isle of 
Axholme, and at the exact point of junction—on the Black Bank 
Drain—of the three counties of Lincoln, York and Nottingham, 
we (my friend Mr. W. Eagle Clarke, F.R.s.E., now head of the 
Natural History department of the Royal Scottish Museum in 
Edinburgh, and myself) took a single example floating of 
Vivipava contecta, which at that time seemed to be a new record 
for all three counties. 
Two years later, 1 made the acquaintance of an excellent 
naturalist, the late Mr. James Eardley Mason, of Alford, and in
