Habitation" The Buccina generally 

 inhabit the ocean, with the exception 

 of a very few species, which are found 

 to inhabit the earth. 



Lamarck has divided the jrenus 

 J^uccinum into seven genera : Do- 

 liuni, Harpa, Cassis, Terebra, Purpura, 

 Buccinum, and Nassa. 



The shells composing the genus 

 Buccinum are in general strong and 

 hollow ; they adhere to rocks and 

 stones in the ocean, and deposit their 

 ova in deep water. Some of the larger 

 kinds are said to have been used as 

 trumpets in ancient times. 



In Turton's Linne 202 species of 

 Buccina are described ; and eighteen 

 species have been ascertained to in- 

 habit the British shores. 



Genus 25th.— STROMBUS. Ani- 

 mal a Limax : shell univalve and spi- 

 ral ; aperture much dilated ; the lip 

 expanding and produced into a groove
