Found these two snails in a freshwater ditch in Slimbridge Gloucestershire during some survey work I was carrying out. Any ideas on ID would be greatly appreciated. One with rounded aperture, the other was less so. Both had operculums. Broader than high with the peak only slightly raised. Ditch not particularly well vegetated with only minimal emergent vegetation around margins.
