Buccinum angalosnm Gray is a very good instance to illu- 

 strate the above hypothesis by. 



The normal form is rounded, with a sharply cut 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 distinct until the 

 counecting series ifS studied.
