Hi Thomas,
pleased to hear that terrestrial snails still find amateurs. Try to get a
copy of "Elseviers Slakkengids" (the famous "Kerney/Cameron"). It covers
the landsnails of northwestern Europe and it helps in identifying
Clausiliids. There are also German (published in the Parey Verlag) and
French editions with somewhat expanded geographical areas.
Numerous papers on Clausiliidae have been published by H. Nordsieck and
several other authors in the German "Archiv fuer Molluskenkunde" and also
in the Dutch "Basteria" and in other journals. This family may be puzzling
for a beginner in northern Europe, but that´s nothing compared to the
south!
For more information contact me directly!
Greetings from (a half Belgian in) Germany
Michael
