Description edit
The size of the shell varies between 25 mm and 70 mm. The solid, imperforate shell has a conic shape. It is brown or cinereous. The suture is canaliculate, bordered below by a series of curved radiating tubercles. The 6-7 whorls are obliquely lamellose striate. The upper ones are carinate and tuberculate or spinose at the periphery. The body whorl descends rounded or bicarinate and is spirally lirate. The base of the shell is conspicuously radiately striate. The aperture is obliquely, transversely oval, and pearly within. The columella is arched, white and pearly, with an orange callus dilated over the umbilical region and extending over the parietal wall. The operculum is short-oval, brown within, with four whorls, the nucleus situated one-third the distance across the face. Outsideit is bright orange, polished, with a spiral callous ridge.[2]
Distribution edit
This species occurs in the Atlantic Ocean off Portugal, Western Sahara, the Canary Islands, Cape Verdes, Madeira, the Azores; in the Mediterranean Sea (off Greece, Sicily and the north of Catalonia).
