See text Douglassia is a genus of sea snails, marine gastropod mollusks in the family Drilliidae.

The postnuclear whorls show a broad concave area immediately below the summit, across which the axial ribs do not extend.

The parietal wall shows a heavy callus that forms a knob at the exterior angle.

The sculpture consists of strong axial ribs that extend from the anterior limit of the concave area, where they are strongest over the base, growing feebler anteriorly.

Fine incremental lines are also present on the ribs and in the intercostal spaces.
