Borsonia (Cordieria) ovalis P. Marshall, 1917 (original combination) Cordieria ovalis is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.

(Original description) The small, oval shall has a short spire consisting of 4 rapidly diminishing whorls.

The oval aperture measures rather less than half the length of the shell.

On the body whorl the costae decrease anteriorly, and are not distinct on the base.

This shell, owing to the coarseness of its sculpture, has a somewhat rude appearance, and is very characteristic.
