BUCCINUM. 401 



Unfortunately the name Buccinum has even of very late 

 years been applied to such a heterogeneous assemblage of 

 shells that it is difficult to disentangle those to which 

 we restrict the name from a number of very different 

 forms having no true generic affinity with them. 



These mollusks appear to have commenced their exist- 

 ence during the later tertiary epoch. At present they 

 have the power of enduring very variable conditions of 

 depth and locality, though the geographic range of the 

 group is limited, however widely may extend the areas of 

 some species.
