GENUS BUCCINUM. 3 
The Buccina are carnivorous animals, provided with a cylin- 
drical trunk, susceptible of being much elongated or of being 
concealed entirely within the body; this trunk is armed at its 
extremity with beaks, which enable the animal to pierce the 
shell of other mollusca, upon which it preys. 
The sexes are separate. The shells of the males are gen- 
erally smaller, and less inflated than those of the females. The 
males are provided with a very large exciting appendage, which, 
in a state of repose, is situated under the right edge of the 
mantle. 
The eggs are generally united together ; they are sometimes 
driven and transported by the waves to distances far removed 
from the places where they had been deposited; whence the 
same species of Buccinum are often found in very different 
climates. : 
The Buccina are met with in all seas, especially upon rocks, 
where they are in large numbers; the warmest climates furnish 
the species most brilliant in coloring. Some species serve for 
food to the inhabitants of many countries, particularly upon the 
shores of the Channel.
