I saw these strange looking snails on the edge of an arable field this morning. I'm pretty sure that this is Candidula gigaxii, a species I have not seen before. The shell is less wrinkled and with a more rapidly expanding outer whorl than it's close relative the much commoner Candidula intersecta. They were also climbing around in rank herbage which also fits, as intersecta is meant to prefer shorter turf. I was surprised that there was no reference in the literature to how white the body was. I'd be interested if anyone has seen this species for their comments.
