The larger specimen in the centre only has about 4 whorls - it could be an immature brown lipped snail C.nemoralis. It appears to have a pale flexible edge to the shell (indicating an immature of either species) rather than a distinct thickened white lip (indicating an adult specimen of C.hortensis).
