Land Snails of British Isles (2nd edition)

This AIDGAP identification guide covers all 100 outdoor land snails found in Great Britain.

There are four sets of keys. The first two keys offer two alternative routes to taking identitifcation to family level. One is a pictorial key, using shell height to width ratio and shell size. The second key is a more traditional dichotomous key to families.

The final two keys take identification to species level. The third key uses dichotomous and tabular keys where these are appropriate. Difficult identitifications are covered in the fourth key, for the small number of species where identification requires dissection.
