|Comments and Corrigenda
||The figures aren't numbered quite sequentially. No doubt there was a good reason, but it can be slightly confusing.
||About 140 commonest of the 230+ British species known at the time. The others are rare.
||Line drawings, mostly of shells.
||In the Hand (also useful to examine with x8 or x10 hand lens).
||The keys are for identifying whole animals. Features of the soft parts are often used so there may be problems identifying dead shells.
