Dear Erwin,
This is a species of Pleurobranchaea. There are a number of species apparently occurring in the Mediterranean and the eastern Atlantic which all look very similar externally. Following Marcus & Gosliner's (1984) review it would need a look at its anatomy to identify it to a species.

Besr wishes,
Bill Rudman.
