Description

The length of the elongate-ovate, black shell attains 8 mm, its diameter 3 mm. The shell contains 7½ whorls of which 1½ in the protoconch. The upper half of each whorl is concave, and not crossed by the ribs, which are situated below. Of the three spiral lirations which connect the ribs, the upper one is rather more slender than the others. There is a slight thickening just below the suture.. The body whorl contains 15 spiral ribs. The small aperture is red and measures ⅓ of the total length of the shell. The sinus is small and is slightly situated below the suture. The siphonal canal is very short.[2]
