More views please

from the side and underneath.
We also need to know the size.
Littorina 15mm, Euspira catena 30mm.
Have a look at the marine snail shells at http://www.conchsoc.org/groupbrowser/Marine%20snail
and http://www.marlin.ac.uk/speciesinformation.php?speciesID=3325

There more to this than I'd first seen.
First, Littorina mariae is now L.fabalis.
I am certain it is not either of those.
This picture looks like E.catena (which I have never knowingly seen) but the size difference is quite significant Keith.
