Dear George

The name of the Cistula species in the museums
collection from the old Biasioli collection before
1900 are pallida and radula. I eventually want to
know the right genus and author and family.
Could I have more informations of these two species
thank you best in advance and with best shelling
greetings.
Helmut from Innsbruck
