Perrinia elisa is a species of sea snail, a marine gastropod mollusc in the family Chilodontaidae.

The thick, solid, imperforate shell has an acutely conical shape.

The rest of the whorls (7 to 8 in all) are traversed spirally by three strong cords, the central one narrowest, all closely beaded by the decussation of close, regular, elevated lamellae of increment, which sharply sculpture the interstices.

The body whorl is angled at the periphery, and bears 7 concentric lirae on the base, the inner ones smaller.

The short columella is subvertical and cylindrical, with three or four small, transverse, rather acute folds on the lower half.
