SCHEME FOR THE DIVISION OF BRITISH MARINE 

 AREA INTO CENSUS AREAS.

(Read before the Society, June i8lh, igig). 



While the land and freshwater mollusca of this country have been 

 intensively studied in a great variety of aspects, there still remains a 

 great quantity of work to be done on marine mollusca, all round our 

 coasts. Apart from dredging, even the littoral fauna offers a multi- 

 tude of problems to which any of us who live near the sea may 

 contribute valuable data. In my own records I have long used a 



division of the British coastal seas into areas, and recently have f 

 attempted to define these areas in detail. The present scheme is ' 

 tentative only, and probably calls for much revision, especially in 

 Irish waters. Perhaps a Committee might be appointed to examine 

 its practicability and authorize some definite system of Census Areas.
