Description

The shell size varies between 3 mm and 6 mm,^{[citation needed]} and features a hole at or near the top of the shell.^[2] The height of the shell is shorter than its width and a sculpture of granular riblets radiate from the apex, both of which help distinguish the species from the related P. alicei, which has a smooth shell taller than it is wide.^[2]

Mosquera et al. (1981) and Mosquera (1983) misidentified a Puncturella agger specimen as belonging to this species (then called Puncturella profundi).^[3] While P. agger shares the radial rows of granules with Profundisepta profundi, it is distinct in that there is a slit, rather than a hole, near the top of the shell, stretching from the apex to the anterior edge.^[2]

Distribution

This species is distributed in the Northern Atlantic Ocean along Iceland and Greenland.
