(Described as Zeidora legrandi) The white, delicate shell is depressedly conical and cap-shaped.

The apex is minute and short, hooked and somewhat adpressed, almost reaching the posterior margin.

In the apical region the ornament is extremely fine, but beyond it the cancellation is visible to the unaided eye (there are about nine rows of rhombic spaces in a radial distance of 2 millimetres measured from the periphery).

The fissural band is margined on each side by an elevated rounded keel, which is crenately sculptured.

The septum is narrowly crescentic (extending in the middle line to about one-fifth and on the sides to about one-fourth of the length of the aperture), much depressed posteriorly (about one-half the depth of the shell) becoming shallower on the anterior border, which almost reaches the base of the shell.
