Of conchologists outside the county, many have collected in 
it at one time or another. Amongst others, Mr. Fred. Rhodes, 
the Curator of the Bradford Cartwright Museum natural history 
collections, has spent holidays in two successive years at Mable- 
thorpe, and has given me notes of his captures. 
So much for the history, with which I fear I shall have 
wearied you. 
The present state of affairs is very simply stated. We wish 
to complete the investigation during the coming year—1g10—if 
possible, with the view of publishing a complete, elaborate and 
exhaustive account of the Land and Freshwater Mollusca. 
What remains to be done is this. The county is divided into 
34 districts which have been unevenly worked. For the 
Holbeach district we have not a single species, record or note of 
any kind, and for the Louth district there are 84 species on 
record,—the numbers recorded for the others varying from 7 to 
79. Striking an average 18 districts are below and only 16 
above it.* 
We cannot, of course, attain perfection, but we should like 
this year to devote special attention to the districts which have 
so far had the least attention paid to them—and such of our 
friends who are desirous to help and have choice of place would 
do well to direct their attention to some poorly-worked area 
lying conveniently for them. 
There are now not many species one may confidently expect 
to meet with. Nevertheless, the existence of Limnea glabra, now 
supposed to be extinct, ought to be confirmed by new discovery. 
Mr. Peacock believes he has once seen Limax tenellus at 
Linwood Warren, and I think he was right in his surmise—but 
We require the actual confirmation that the sight of one example 
would give. 
Zonitoides excavatus has been seen once, and ought to be found 
- again.+ 
* P.S.—June, rgto. These statistics are as given in December, 1909. 
Research this year in the Holbeach, Long Sutton, Horncastle, Crowland, 
ee and Grimsby areas has considerably altered the state of things.

t+ P.S.—In May, 1910, Mr. Musham and I re-discovered it in Tumby 
Wood.
