(Original description) The minute shell is black, with a paler band at the posterior edge of the body whorl and a half. The shell contains about six whorls. The protoconch is smooth and somewhat irregularly swollen. The suture is closely appressed. The axial sculpture consists of about 20 narrow low threadlike ribs with subequal interspaces. The spiral sculpture consists of faint obsolescent striae between the ribs and two or three threads on the siphonal canal. The aperture is narrow. The outer lip is sharp. The aperture is blackish. The columella has three dark plaits. The siphonal canal is hardly differentiated. [2]
