Filodrillia ornata is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.

(Original description) The small shell is rather solid, turreted and has a subcylindrical shape.

Sculpture:— The flattened and conspicuous fasciole carries three or four small spiral threads.

The remaining spirals are sharp cords, narrower than their interspaces, larger and wider apart on the periphery, about fifteen on the body whorl and five on the penultimate.

The radial riblets, so faint as to scarcely appear in the intercostal furrows, form beads on these spirals.
