  • "Shell reaching a height of about 80 mm, moderately slender. Protoconch and earliest teleoconch whorls not known. Earliest preserved teleoconch whorls sculptured by eight axial ribs per whorl, which are overridden by eight spiral threads.

Number of spiral threads on penultimate whorl 13. Number of preserved teleoconch whorls seven. Dorsal surface of body whorl with three spiral rows of knobs. The most adapically situated row not prominent, the others prominent. Remainder of dorsal side of body whorl sculptered by spiral and axial threads. Aperture long and narrow. Parietal callus smooth. Outer lip only slightly flaring, its inner surface smooth with the exception of a few faint, spirally elongated denticles on the adapical and abapical part. Sinus small. Base of columella bent backward."
