Zacconi 16, 50137 Florence, Italy; e-mail: [email protected] *Corresponding author ABSTRACT Coen introduced several new nominal taxa in the Pyramidellidae and in most Mollusca families. The Coen types, now at the Hebrew University of Jerusalem, have been examined; most of them are holotypes or lectotypes. Some lectotypes were already selected by van Aartsen, as stated in the label, therefore we have not done any further selection of types. The new pyramidellid species have been practically identified and named by Monterosato, and were all found in shell grit collected on the beach of Lido (a small island in front of Venice). None of the Coen’s new species seems to be valid. KEY WORDS Coen collection; Pyramidellidae; Adriatic Sea; Mediterranean Sea.

In some cases Coen understands that even if Monterosato considered that shell as a variety, and MATERIAL AND METHODS assigned a variety name, the differences are so small that should not be the case.
