Brown skin on shells aka the periostracum
This brown skin layer we sometimes find on shells is a natural partof the shell itself. It is grown by the creature to protect the shell itself. In some cases it wears off but, when it exists, it can make identifying the shell underneath pretty difficult.
King Scallop
Pecten Maximus
Bivalve
Distinguishable by its large size, non-matching halves (one convex, one flat, differing colours) and symmetry.
See this shell in Shells Live!
Queen Scallop
Aequipecten opercularis
Bivalve
Smaller than the King Scallop (generally smaller than 9cm across) and the two halves are more similar to each other than the Kings although still non-matching. Generally perfect symmetry in its shape ie.matching ears.
Variegated Scallops
Chlamys varia
Rarely longer than 6cm, this tends to be smaller than either the Queen or King Scallop and is not as round in shape. It has non-matching ears.
Humpback Scallop
Chlamys distorta
Generally smaller than the variegated scallop, it looks like a melted, distorted verson of it.
Tiger Scallop

A small scallop which is very much smoother than any of those above.
l. Common European Turritella aka screw shell aka auger shell
Turritella communis

Tusk shells
Common tusk shells
Dentalium vulgare

Acanthocardia tuberculata
True cockles have visible grooves ratiating from their 'noses'. In rough cockles, these are particularly deep.

Limpets
Patella sp.
See this shell in Shells Live!
Limpets are formed of just one conical shell. There are three species of limpet we commonly see in the British Isles but it is not often easy to tell them apart without seeing the limpet snail itself.
This is partly because the shells of the three species are very similar but also because they are often covered in barnacles or seaweeds and also, patterns, colours and ridges get worn away as the animals age.
Common Limpet
Patella vulgata:
most commonly seen living high up n the shore where it is frequently exposed at low tide. If you get to see the body, it is yellowish, often pale.
Black-footed Limpet
Patella depressa:
found living lower down the shore and has a black body.
China Limpet
Patella ulyssiponensis:
found living where it is not exposed by low tide often. Has an orangey body.
Chinese hat snail aka Chinaman's hat
Calyptraea chinensis
Like a small limpet, with an often pronounced 'nipple' on top.
Keyhole Limpet
Diodora sp. / Diodora graeca

Sugar Kelp Emarginula
Emarginula octaviana
A small relative of the key hole limpet
Necklace Shell aka Moon snail
Euspira catena
Dog whelks
Nucella lapillus
Found in a variety of colours, stripes. Characteristised byit very thick shell which protects it from the harshness of rockpool life.

Cat's eye shell
Turbo sp.
This is actually the operculum, or trapdoor, used to cover the opening of the turbo sea snail's shell. While the whorl / spiral effect makes it look like a shell, it is solid - flat on one side and stone-like on the other.
Common Atlantic Corbula
Corbula gibba
Faroe Sunset Shell
Gari fervensis
It is identifiable by the sharp 'bend' in its shell on one side of each half with the radiating colours giving it its sunset name..

Arca Shell
Arca tetragona
An unusually deep bi-valve.
Banded Wedge Shell
Donax vittatus

but which are not from sea snails
Some shells can be found on the beach which may have come from the dunes or green land around the beach.
Garden snail
Helix aspersa
A common snail in our gardens, its very thin shell can be found often on beaches as can live creatures.
Sandhill Snail
Theba pisana
A relatively large snail, abouth e size of a garden snail. A thin,delicate shell.
Brown-lipped snail
Cepaea nemoralis
An incredibily variable snail. Both colours and the presence of stripes can vary, along with the number and width of stripes. However, the dark line at the edge of the opening remains a constant. These are very delicate shells and tend to more likely to be crushed underfoot on the beach, more so than many sea snail shells.
Round-mouthed snail
Pomatius elegans
Unlike the other land snails listed here, the round-mouthed snails has a much thicker more robust shell not unlike that of a rockpool snail.
