variation

Yellow Shell is very variable in its depth of colour and amount of banding, and I wouldn't see that as evidence of different subspecies.

There are, I think, 4

There are, I think, 4 subspecies in the UK - two small and dark subspecies restricted to the Scottish islands, and two large and yellow, as here (bilineata & hibernica), which seem to be nationwide.

I can't find the distinguishing features that separate the two - it seems to be connected to the amount of brown in the banding, but I can't see anything obvious to suggest it's not just a continuum.
