From leaf litter. This was about 4mm across, so I came to the conclusion that it might be Aegopinella pura - is it possible to confirm?
No interactions present.

Correct size and number of whorls but I cant see the microsculpture of the shell. I find it hard from a photograph but if you have reference specimens of each it should be easy.
I have a blurred photo of an empty transparent snail shell similar size - it was caught in a cobweb on a treetrunk in a deciduous wood on chalk. From your comments, it won't be identifiable to species but is there a genus or other group I could narrow it down to? I know next to nothing about snails yet.
Zonitidae it the wider sense as used in Kerney & Cameron. Checklist at http://www.conchsoc.org/recording/checklist.php
For modern view see http://molluscs.at/gastropoda/terrestrial/zonitidae.html
Thanks!! That's great!
The radial growth lines were fairly clear, but the spiral striae were not at all clear - I thought I could just make them out in places but they weren't as clear as the key seems to indicate. So my judgement was on size and number of whorls, but it looks like this one will have to remain unconfirmed.

If so I can check it against the material in the University Museum of Zoology, Cambridge
I do keep specimens sometimes, but didn't in this case I'm afraid. Will see if I can find some more of them.
