Those are some gorgeous snails! I had one with that same colour variation, it's interesting how mine also had the smaller cream band alongside the black. Unfortunately my snail, Stripey, passed on because of mantle collapse but from his shell I created a necklace in his memory, and this pattern is a very beautiful and striking one. It looks better on the snails though! This is definitely my second favourite colour variation, my favourite has to be unbanded though, I've never actually seen or owned any unbanded Cepaea!
Yeah these guys are a great pattern. I love the sunny days but I have to say some days I wish for a quick rainshower so I can get my dog and go hunting! lol These are pretty much the only type I still pick up nowadays though!
