Of the species referred to last year, I have little further to say, 
except that their apparent abundance has been fully confirmed 
this season, and that I have had the pleasure of confirming Lord 
Walsingham’s notice of the occurrence of the very local and 
elegant Gelechia 'pidelJa, whicli seems to be tolerably common in 
the Brandon district. 
Two other southern coast species, AspUates citraria and Catop- 
tria citrana, also occurred there in August, in considerable num- 
bers, and are interesting as collateral evidence, although I do not 
think that they are, either of them, quite so exclusively littoral in 
their habits as those previously noticed. Moreover, common as 
they both ai’e in certain localities on the south coast, they appear 
to be either scarce, or extremely local on that of Norfolk.

THE MARINE MOLLUSCA OF THE NORFOLK COAST, 
fABSTRACT.J 
By F. W. Harmer, F.G.S. 
Read 28th November, 1871. 
There is, perhaps, no portion of the natural history of our county 
which has received less attention than that which treats of the 
Marine Mollusca of our coast. The only list of them Avith Avhich 
I am acquainted, is one given on the authority of the late Rev. O. 
IMunford, of East Winch, in a small pamphlet on the Natural 
History of Hunstanton published in 1867, Avhich hoAvever contains 
but about thirty species, and these principally distinguished by 
names Avhich have now become obsolete. One of our hand-books on 
this subject, the “British MoUusca ” of Messrs. Forbes and Hanley, 
gives but four shells from the Norfolk coast, two of Avhich, Area 
lactea and Tellina donacina, I have not yet met Avith ; Avhile the 
more recently published “British Conchology” of l\Ir. J. OAvyn 
Jeffreys alludes to but three, though both these Avorks contain 
numerous localities for tlie species do.scribcd in them.
