The size of the shell varies between 20 mm and 40 mm. The umbilicate shell is typically more elongated than Lunella coronata with an altitude about equalling the diameter. It is finely granulose all over, with subsutural and coronal series of tubercles, and sometimes one or two additional series upon the median part of body whorl.[2]
