Shell medium in size, about 11 mm. in length, solid, pale cream yellow in colour, height being about 60 % of the length : aperture elliptical; anterior slope convex; posterior slope slightly concave or straight; apical whorls one and one half in number and are reduced to a small hook; the position of apical whorls close to a little below the summit and situated at the posterior end; anal fasciole narrow, provided with transverse lamellae; fissure narrow, its length being one-fifth of the anterior slope; sculpture consists of about 40 radiating ribs from the apex; below secondary ribs appear between each two of the primary ribs; numerous concentric cords divide the spaces between ribs into small square pits.

Height 8.2 mm., length of aperture 13.6 mm., breadth of aperture 10.1mm. (type specimen collected by Mr. Akibumi TERAMACHT).
Height 4.5 mm., length of aperture 8.6 mm., breadth of aperture 6.0 mm. (paratype).
Height 4.8 mm., length of aperture 8.9 mm., breadth of aperture 6.5 mm. (examined specimen collected by Mr. Kakujiro HOSOYA from the Sagami Bay, 50 fathoms in depth).
Height 5.1mm., length of aperture 8.9 mm., breadth of aperture 6.6 mm. (examined specimen from the Sagami Bay).
