Animal albidum, immaculatum. Oceuli aterrimi. 
Habitat in littore scopuloso, vulgaris. 
Shell with moderately convex whorls, which are elevated into 
longitudinal lines, and are transversely lieolated with little 
antiquated lines, which in the young shells are elevated into 
curved or spimous lamelle. Height 2 to 22 inches. Breadth 
1 inch. 
The animal is whitish, without spots. The eyes are very 
black. 
All the rocky coasts of Britain produce this species in very 
great abundance. It is subject to great variety of form, as well 
as of colour; it is white, luteous, croceous, brown or purple, 
plain, or banded with one or more of those colours. In much 
exposed situations its apex is much depressed; and in very 
sheltered bays the adult shell has all those elevated lamella 
which it always has in its youthful state.
