Description

The shell is described as thin and "egg-shaped"[3] with very rounded whorls. The spire is short, and the apex may become worn out in older specimens.[3] The name malleatus derives from Latin malleāre (to hammer) and refers to the "hammered-like sculpture" often found on the shell of this species.[3]
