It is very abundant at Bermuda, among rocks and in tide pools at 

 low-tide. It occupies many kinds of small gastropod shells, such a- 

 Cerithium, Jlochdns, Littorina, ^\'< riflim, Anachis, Columbella, 

 Natica. Frequently it takes jossession of various land shells, com- 

 monly washed ashore. It is sometimes infested by a parasitic isopod 

 crustacean (St,r/;<i.-< cllhunarii Richardson).*
