The height of the shell is 28 mm, its diameter 40 mm. The conoid shell is more or less depressed at the apex. Its color pattern is grayish greenish, or brownish cinereous. The six whorls are flattened above, and radiately plicate, the folds rather unequal and irregular. The periphery is carinated spinose, bearing about twelve radiating more or less foliated spines upon the body whorl. This body whorl descends deeply toward the aperture. The convex base is concentrically more or less densely squamosely lirate. The outer lirae are generally prominent and subspinose, sometimes causing the periphery to appear bicarinate. The aperture is transversely oval, very oblique, generally golden within, and stained with purple or blue on the columella.
