Sieved from soil/litter at the base of a hedgerow
No interactions present.
and then had to look up what "door snails" were all about.
Thanks for an interesting post. I am not familiar with the group, so not sure how likely it is to be this species. Looks right to an entirely untrained eye!
I'm not doubting the identification, but I always struggle to distinguish Clausilia bidentata from Cochlodina laminata. What features did you use to decide on Clausilia?

I've now had the opportunity to have another opinion on this specimen and it is Cochlodina laminata. My colleague separates the two species by size and width:height ratio.
C. laminata width:height ratio is about 1:4.15
Cl. bidentata width:height is about 1:4.4
It seems to work!
