The axial sculpture consists of about 15 low, short oblique ribs most prominent at the shoulder, with wider interspaces and obsolete in front of the periphery. The spiral sculpture consists of faint spiral striations visible only under the lens. The aperture is subovate. The siphonal canal is long, narrow and straight. The columella is straight and attenuated in front. [2]
