It is, about twice as long as broad, arched. The minute spire is flat and consists of two whorls. It is at right angles to the shell's length and terminal. Its colour is white with irregular crimson splashes spirally arranged along the back. Its sculpture consists of fine spiral grooves decussated by growth lines. The peristome is nearly in one plane and is angled above. The columella is slightly thickened.[2]
