PROPOSED RAPID COMPLETION OF THE VICE-COMITAL 

 CENSUS OF BRITISH LAND AND FRESHWATER MOLLUSCA. 



To render more complete the coloured maps of distribution in 

 jNTr. John W. Taylor's comprehensive and invaluable Monograph, a 

 circular has been issued by the undersigned, with the hearty co- 

 operation of Mr. Fred Taylor, the Recorder of the Conchological 

 Society, and the active assistance of Mr. Fred Booth, for enabling 

 nialacologists to know what species are required for inspection from 

 the various counties or vice-counties. The circular includes a full 

 list of the British species. When sent to a worker for any particular 

 area, all species are scored out which have already been authentic- 

 ated by Mr. John \V. Taylor. The idea is that workers should 

 submit for inspection any species left unmarked. 



The result has already been satisfactory — for 500 of the blanks 

 have been filled up (for 47 counties), thanks to Miss A. L. Massy, 

 Mrs. Carphin, Dr. Scharff, and Messrs. L. E. Adams, F. H. Sikes, 

 A. H. Jowett-Murray, J. R. le B. Tomlin, B. R. Lucas, J. E. Cooper, 

 J. F. Musham, G. D. H. Carpenter, E. D. Marquand, A. Mayfield, 

 C. H. Moore, J. N. Milne, A. Eoydell, C. Oldham, R. Welch and 

 A. W. Stelfox, and assistance is promised by Mrs. d. B. Eongstaff, 

 and Messrs. Hugh Watson, J, Williams Yaughan, J. Roseburgh, 

 and C. P. Richards. 



Will conchologists send for marked lists, more particularly for areas 

 in which they have collected but are not resident ? 



Collectors planning expeditions to outlying areas are desired to 

 ask for marked lists — more particularly for districts in Scotland, 

 Wales, Ireland, and the western promontory of England. 



Of unworked areas County Longford is the most conspicuous 

 instance, for so far only two species have been authenticated — both 

 slugs. Various Scottish counties (Wigtownshire particularly) have 

 been very scantily worked, and in England Hunts, and Monmouth 

 are but little represented in the records — while for numerous well- 

 worked areas there are common species not yet authenticated.
