' additions to our local molluscan fauna ; in fact, in one or two cases, 
to record shells which are not even in Alder’s classical list, and others 
which are decidedly rare. Several of the shells mentioned below, 
recorded in a previous list, were then only represented by dead or 
immature specimens, but have now been found living and abundant 
con our coasts,
