•This, altliough by far the most copious of any hitherto given, must be considered as a very iinpor- 



fecl nomenclature of the shells of North Britain, especially of the more minute species. It is 



however remarkable that amongst a large parcel of sand replete with microscopic shells, wilh 



which the author was favoured by his friends from the shores of the Frith of Forth, only one 



new occurred ; indeed the species were by no means so numerous as might have been expected. 



Much however remains to be douc ia the oorlli| and luucb way be c;ipected through the medium
