We have been careful, in drawing up the above list, to confine 

 the catalogue almost entirely to shells taken in a livmg state — 

 cases of divergence from this rule being invariably specified. 

 Otherwise the list might have been considerably enlarged. At 

 the same time, there are several other L-and and Fre.-ih-water Shells 

 known to inhabit the islands, which we were not fortunate enough 

 to obtain on this occasion. Helix aculeata, for instance, is found 

 in Guernsey, and so are Splicerium corneum and Sp/ucrium lacustre, 

 while Testacdla Haliotidce occurs abundantly both at Guernsey and 

 Sark.
