Lots of these conical brown shells of varying sizes crawling over felled conifer log bark.
No interactions present.
Picture 2 is Cochlodina (Cochlodina) laminata
Are the teeth less obvious in the live animal?
Yes, the animals are covering the teeth.
Balea is only 6-8 mm long and a different shape
Thanks for the info. I could have sworn I took photos all of the same individual, but I must have muddled them up. One of the problems using photos for ID.
I have agreed to the the one on the left as C.bidentata and the one on the right as B.perversa - it is pretty barrelled.

not Balea. Balea would have a narrow lip and a rather squarish mouth. In Cochlodina the lip is bluntly thickened and reflected as in the right hand photograph. If we were given the size dimensions it would be even more obvious.
You are right (of course) looking at mouth shape only, this then, I think, is also likely to be C.bidentata.
shows a snail with a glossy shell and weak striations.
Clausilia bidentata is strongly and deeply striated.
