WINCKWORTH, , (Read before the Society, June i8lh, igig). While the land and freshwater mollusca of this country have beenintensively studied in a great variety of aspects, there still remains agreat quantity of work to be done on marine mollusca, all round ourcoasts. Apart from dredging, even the littoral fauna offers a multi-tude of problems to which any of us who live near the sea maycontribute valuable data. In my own records I have long used a. division of the British coastal seas into areas, and recently have fattempted to define these areas in detail. The present scheme is tentative only, and probably calls for much revision, especially inIrish waters. Perhaps a Committee might be appointed to examineits practicability and authorize some definite system of Census Areas. WINCKWORTH : SCHEME FOR BRITISH MARINE CENSUS. I53 The main object is to get a system which shall really help to repre-sent the British distribution of marine species, and stimulate interestin their study. Admiralty Chart No. 2—British Isles—is a convenient chart towork on, giving the whole British marine area as far as 15° West, onthe average scale of 2|- inches to a degree. For land and freshwater moUusca, counties and sub-divided coun-ties have been taken as the census unit, but for marine mollusca Ibelieve a far larger area would in most cases be more for coastal areas, the county borders do not as a rule d
