Buccinum angulosum Gray is a very good instance to illu- 
strate the above hypothesis by. 
The normal form is rounded, with a sharply eut uniform 
body-sculpture and very faint subsutural riblets mostly in 
the smaller whorls. The variety with stronger longitudine 
ribs is rare and they are not, at most, remarkably pro- 
minent; but in the carinated variety they become very 
strong, through they may be shown either as ribs from 
suture to carina ending in nodes, or they may appear 
solely as nodes which gives a form superficially most 
remarkable and one would suppose it distinet until the 
connecting series if studied.
