« If much diligence were used in the research, it might be possible to find, perhaps, as many more as those enumerated above, differing from them either in genus or species; but these are all we could collect, after several examinations of the bank; and having little information on the subject ourselves, they have been submitted, in the first instance, to the Countess of Dalhousie, and subsequently to Mrs. Sheppard, of Woodfield,— two females whose refined tastes have led them to a successful cultivation of more than one branch of Natural History ; and to one or other of these ladies we are indebted for the above quoted names. Mrs. Sheppard observes on the singularity of finding a fresh water shell (melania) mixed up with the others which are exclusively of marine origin. The fact would seem to imply, that when this bank of shells was deposited land was not far off. »
