In the Proceedings of the Geologists' Association for 1878, Mr. W. H. Shrubsole, F.G.S., published a list of Foraminifera obtained from the London Clay of Sheppey. The following list, the result of an examination of some material courteously lent to us by Professor J. W. Judd, F.R.S., adds considerably to the fauna of Sheppey and includes two species not previously recorded from the London Clay. Forty-one forms have been determined, of which twenty-six. are new to Sheppey, thus bringing up the number of forms recorded from that locality to eighty-six. The geographical distribution of the Foraminifera of the London Clay was fully tabulated in 1886, and it is interesting to find so many of the forms there figured and recorded for the first time from the London area common to both localities. The figure following the specific name in the list appended shows the relative abundance of the varieties found.
