 inches and a quarter broad, and the number of its scaly ribs 

 varies from seventy to about one hundred ; the shell also varies 

 greatly in colour, which is sometimes only pale reddish, with 

 darker concentric bands, or often. yellowish, or dark red, 

 with purple bands, and Dr. Shaw has figured a beautiful va- 

 riety, with purple, black, and crimson bands. Gronovius 

 says it is an English shell, and my late lamented correspon- 

 dent, Mr. Montagu, informed me of its having been found 

 on the coasts of Scotland. Sir Joseph Banks procured a 

 specimen from the stomach of a cod on the Banks of New- 

 foundland.
