Help me find out this ones name

[paul monfils]

This is Neptunea contraria, a fairly common deep water species found in the eastern Atlantic from Spain to Morocco.  It is a normally sinistral species, meaning its shell coils in the opposite direction from most other Neptunea species, and most gastropods in other families as well. That's what its name refers to. The direction of coiling is "contrary" to the direction typically seen in most species. Such shells are often referred to as "left-handed".
