G.W. Tryon thought this species was a synonym of Cyclostrema peterseni Frielle, 1877 (now a synonym of Skenea peterseni (Friele, 1877)) [2]
Description
The size of the shell varies between 2 mm and 3 mm. The white shell is perforate, somewhat solid. It is opaque, smooth, and shining. The base of the shell contains sometimes a few faint oblique, curved lines;. The four whorls are convex and have a deep suture. The columellar lip is vertical, forming a slight angle with the outer lip at their junction.[2]
Distribution
This species occurs in Arctic waters and in the northern Atlantic Ocean off Greenland, the Faroes and Scandinavia at depts between 60 m and 160 m.
gollark: Hmm, it seems to be >2KB.
gollark: All in less than two kilobytes of Python! I think!
gollark: Basically, my WHY JIT compiler sticks your actual code into a skeleton with the busy loop, then embeds that into a shell script which writes a C compiler (embedded at the end of the script using a bizarre quirk of shell scripts where you can just stick anything in after an exit and it won't care) to a temporary file, writes the skeletoned code into another one from a heredoc, executes the C compiler temporary file with the code temporary file as input (it outputs to another temporary file), executes the result, and exits with the return code.
gollark: Void main got popular, so they just allow it.
gollark: Lax compilers.
