Description
The shell is described as thin and "egg-shaped"[2] with very rounded whorls. The spire is short, and the apex may become worn out in older specimens.[2] The name malleatus derives from Latin malleāre (to hammer) and refers to the "hammered-like sculpture" often found on the shell of this species.[2]
