The localities of this genus are the Indian, Northern, 

 and Atlantic Oceans, the Red Sea, &c. Many of the 

 species are transversely striped, and are covered by an 

 epidermis. F. longissimus is a remarkably long, turreted 

 shell. F. colosseus is very large, often found more than 

 eleven inches long; and other species are five or six; 

 many of them are very graceful in form and beautiful in 

 structure ; but the colours are not vivid. F. pagodus is a 

 beautiful shell, the whorls being coronated. The animal 

 of F. antiquus is eaten in Scotland, and called "red 

 whelk," or " buckie." — There are six British species.

 thick ; spire of a moderate length ; aperture 

 oval ; canal rather long, sometimes slightly 

 bent; right lip sharp, and often wrinkled or

 and the operculum exactly so. — 16 species J; 

 also fossil.

 the Isle of France, also found in the Medi- 

 terranean. They are not numerous, the colours rather 

 brighter than those of Fusus. F. dislans is a beautiful 

 shell.

 shaped ; spire short ; mouth oval, with cither a long or 

 short canal ; left lip with from three to five plaits, which
