Very common, in the littoral zone, on every part of the coast. 
It is extremely variable. 
Genus — B uccinum. 
B. undatum, Linn, (the “ buckie.”) 
Very common, in all our laminarian and coralline zones. It 
varies to such an extraordinary extent that one can hardly realise 
that it is all one species. The solidity of the shell depends upon its 
environment, so that one may obtain a specimen from the rocks near 
low tide mark of a slatey colour, very solid, the mouth more than 
half the total length of the shell, and the outer lip slightly reflected 
and about quarter-of-an-incli m thickness; and then, take one 
from a sandy part of the coralline zone of a light buff colour, very 
thin, the mouth barely one-third the total length of the shell, the 
outer lip not reflected, and no thicker than parchment. The two 
preceding descriptions are from actual specimens.
