Habitation. The Volutes have on- 

 ly been found to inhabit the ocean, 

 and are most common in inter-tropical 

 climates. 



The French writers on Conchology, 

 have divided the Linnean Volutce into 

 several new genera: Oliva, Turbinella, 

 Mitra, Harpa, Musica, and Volva. 



In Turton's Linne 144 species of 

 Volutes are described ; and eleven 

 species have been found to inhabit the 

 British seas.
