Hi Carlos and other friends
 
Eulima belongs to the family Eulimidae, also according
to: Checklist delle specie fauna italiana a cura di A. Minelli,
S. Ruffo, S. La Posta 1995.  Melanellidae went in synonomy
with Eulimidae. So its possible to find in some works Eulima
under the family Melanellidae.
 
In my collection I have Cymbium olla from the harbour Valencia Spain collected without animal  by an Italian friend. Gianluigi Bini.
For Cerithium vulgatum I looked into F. Nordsieck: Die europäischen Meeres-Gehäuseschnecken : He ranges this
species from the Mediterranea to the Kap.
Hope I helped you.
Helmut from Innsbruck
