Finella pupoides is a species of small sea snail, a marine gastropod mollusk in the family Scaliolidae.

Its color varies from white to pale yellow, a few times even dark brown.

The shell shows typically two indistinct brown bands below the suture and at the base.

The shell is elongate, fusiform with a narrow, pointed apex.

The sculpture of the teleoconch has characteristic flat-topped spiral cords with rather weak axial ribs.
