Description

The length of this very rare shell attains 3 mm, its diameter 1.25 mm.

(Original description) This is a minute turreted pale brown species. The shell contains six whorls, angled just below the sutures, then straight. The straight longitudinal ribs, few in number, are crossed by lirae, conspicuous and large for the size of the shell, six at the penultimate whorl, nine on the body whorl, and less in proportion (e.g. four in the antepenultimate) on the other whorls. The aperture is narrow. The sinus is large and hollowing across the outer lip; which is somewhat thickened and obscurely toothed within.[1]

Distribution

This marine species occurs off the Loyalty Islands and off Mactan Island, Philippines

gollark: And you could finally achieve the dream of people for generations - 10-gigabit ethernet to the phone.
gollark: But you'd get that satisfying click when you plug in your phone.
gollark: I wish they would use a sensible connector, like RJ45, and supported power over ethernet charging and data transfer.
gollark: At this point it might actually be cheaper to just get an identical replacement model, since the company making the phone seems to have run into financial troubles recently and thus sell the same phones at dirt-cheap prices.
