Five whorls remaining in the decollate specimen studied. The suture is channelled. The earlier whorls are sculptured by fine close radial riblets developed on the periphery and vanishing towards the suture. These disappear on the body whorl, which is smooth Between the riblets run spiral threads. The aperture is elliptical and shows four plaits, decreasing anteriorly. The siphonal canal is short.[2]
