Description

The size of an adult shell varies between 15 mm and 55 mm. The shell is whitish, or has a yellowish flesh-color, or brown. It is more or less decussated by longitudinal and revolving engraved lines, sometimes forming granulations especially on the spire. The revolving lines are prominent on the body whorl, where the longitudinal ones are usually subobsolete. George Washington Tryon, Manual of Conchology vol. VI p. 235; 1884 (described as ''Pusionella milleti'')
