This species attains a size of 120 mm with a degree of variation in color and sculpture strength, particularly the size of spines and varices.
(Original description in French) This subclaviform shell is solid and features a long siphonal canal. It is yellowish-white or tawny in color. It is ornamented with finely decussate (crisscrossed) transverse ribs and strong tuberculate (knobbed) longitudinal ribs. Three varices are present per whorl in the spire, each surmounted posteriorly by long, straight, channeled spines and elevated, thin, pleated crests. The spire consists of 9 to 10 very convex whorls, which increase gradually in size, separated by a deep suture. The aperture is oval, and the columella is white, reflected, and thick. The peristome is subacute (slightly pointed). The siphonal canal is elongated, narrow, and slender, angulate at its posterior third, and barely raised dorsally.[2]
