Polyspirella trachealis is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.

They are obliquely immersed in the first of the succeeding turns, above which only the tilted edge of the last two volutions projects.

They are shouldered at the summit, and marked by three strong spiral cords which slope abruptly posteriorly and gently anteriorly.

It is marked by incremental lines and exceedingly fine, spiral striations.
