The size of the shell varies between 40 mm and 60 mm. The imperforate, solid shell has a turbinate shape. The 6-7
whorls 6- are, flat above, obliquely costate below the

body whorl. The base of the shell is a little rounded, radiately lamellose striate and concentrically lirate with three to five lirae, mostly tuberculate, especially in the young. The oval
