WE VARIETIES OF ARION ATER. 



Mr. Wm. Denison Roebuck, Sunny Bank, Leeds, having consented 

 to prepare a paper on Arion ater, similar to that by Mr. Taylor on 

 Helix arbustoru7/i, would be glad if Conchologists would assist him 

 with material, in the way of information and specimens. In particular, 

 it is desired to ascertain which of the numerous varieties described by 

 Moquin-Tandon as occurring in France are to be found in the British 

 Isles, together with the details of their geographical range, both in 

 Britain and. on the Continent. Conchologists may be reminded that 

 the more plentiful the supply of (reliable) information, the better is the 

 proposed paper likely to be.
