The size of the shell varies between 4 mm and 5.5 mm. The small, solid, thick shell has a globose-conic shape, evenly grained all over. it is blackish or pink varied with darker. It is imperforate when adult, and has a groove at the place of the umbilicus. The short spire is conic. The apical whorl is smooth, the following whorl has three granose lirae, the next with 3 or 4; the penultimate has 7 or 8 equal, grained lirae. The interstices are narrow. The body whorl has ten such lirae. The teleoconch contains 5 convex whorls. The last one is globose, descending at the aperture. The rounded aperture is nacre with steel-blue and dark red reflections. It is lirate inside. The concave columella terminates in a tooth, below which there is a narrow notch, and another tubercle or tooth on the basal lip equal in size to the columellar denticle.[3]
