I found the same species of chiton when rockpooling on clachan beach on north uist in the outer hebrides but i haven't managed to identifie it.
I see Tonicella rubra is also intertida & found in the NE,but that usually shows growth lines on the 'shells' (valves)& doesnt have the rough granulations on the girdle that are shown here.
