Hexaplex cichoreus (Gmelin 1791) is correct.
The genus Hexaplex differs from Chicoreus in shell-characters only in
that it has 4 or more varices per whorl; Chicoreus has 3 (abnormal
specimens with more are very rare). Objectively it may be that one of
the two names is not a good genus and should be included in the
other, perhaps with subgeneric status. Both genera were described in
1810, and I don't know which was published first (the first-published
name would have priority if a synonymization is done).
Murex endivia Lamarck 1822 is a synonym, and this specific name
should not be used.
