Description
The 2.0-2.5 x 1.3-1.4 mm. shell has 4-5 whorls and the spire tapers towards the apex. The aperture is simple without teeth . The colour is dark grey brown or horny brown. The surface is not shiny and finely and regularly striated. It is more coarsely sculptured than the very similar Columella edentula.
Distribution
This species occurs in countries and islands including:
gollark: Definitely not a new language, probably a few more terms at most.
gollark: No we don't.
gollark: Except not really that either and mapping on regular computers to it is kind of unhelpful.
gollark: The brain is combined kind-of-volatile RAM and CPU.
gollark: No, analogising it that way is ridiculous.
