Minute snails that just looked like black bits of dirt to the naked eye. Found under a loose bit of bark on a Taupata tree.

Shell very small, tall-spired, smooth, shiny light brown. The parietal lamella shows up as a thin narrow ridge in the ventral view. It also shows that the umbilicus ("navel" of the shell) is closed and how the columella (white) is folded back.
This species occurs in the Wellington Region up to central North Island but not in eastern Wairarapa. Further north it can be found mainly in the coastal areas of Hawkes Bay, East Coast, Bay of Plenty, Hauraki Gulf, Northland and as far south as northern Taranaki. This species is also known from coastal areas of the northern half the of the South Island.

In our aquarium, not sure if it originally came from a pond or river sample.

Small snail that I hadn't really taken any notice of while I was taking photos, but it moved between frames and caught my attention. Picture cropped from second photo (centre, bottom edge). Also see http://naturewatch.org.nz/observations/956041 and http://naturewatch.org.nz/observations/956042 for context.
