Austrodrillia subplicata

(Original description) The short, solid shell is narrowly oval, with a blunt apex and a slightly contracted base.

The aperture is oval, slightly contracted behind, opening widely into a very short siphonal canal in front.

The inner lip shows a complete, applied narrow glaze.

The columella is straight and slightly bent to the left in the siphonal canal.

The shell shows well-marked crowded sinuous incremental striae.
