[3] Shells are reddish brown with darker cross bands, flat and densely ribbed.

The body of this gastropod is bluish black on the upperside, while the lower side is greyish white.

It is also found in Great Britain, Ireland, France, Italy, southern Scandinavia, and other countries.

[8] It does not appear to have the capability to become an invasive pest species in North America, as it lives in leaf litter and forms colonies where the individuals do not tend to spread widely.

These gastropods live in forests and humid shady places, in dead wood logs, under stones, on humus and in soil litter, sometimes in colonies, at an elevation of 0–2,100 metres (0–6,890 ft) above sea level.
