Could be Cerithium coralium but again locality data would help.

This appears to be Batillaria zonale, which has traditionally been placed in the family Potamididae, but more recently the group has been split into a separate family, Batillariidae.

I think you are right Paul, it was hard to tell judging by an upside-down photo! Still need localities though.
