 buco. 350 fathoms. Red mud. 



Habitat. — Guinea (Deshayes) and Martinique (Reeve, Kiener, and British Museum) ; 

 Guadaloupe (Fischer). 



According to Mr Hanley, Turbo exolctus, Linne, is really the Turritella bicingulata, Lam., which 

 is the more in want of a satisfactory name, because Turbo cinctus, Donovan, has priority over 

 Lamarck's name. At the same time, Linne quotes Bonanni (Recreatio, p. 126, fig. 113) alone for 

 his Turbo exolctus; and Bonanni's figure, it would appear, undoubtedly represents not Turritella 

 bicingulata, Lam., but Turritella exoleta, auctorum. In these circumstances, Mr Hanley proposes to let 

 things alone, and I have, hesitatingly, followed him.
