V.—PLEISTOCENE SHELLS FROM COPFORD, ESSEX.
By Wilfred Mark Webb, F.L.S.
No list exists of the shells from this historic locality which
are in the possession of the Club, and the writer has thought it
of interest to compile the following, which indicates from what
collections the specimens had been derived. The most recent
additions are due to the kindness of Mr. Dalton, F.G.S., who
has presented the specimens obtained by the late John Brown,
which formed part of his own collection. These are marked with
his initials (W. H. D.), in addition to the letters J. B., which
indicate the original collection of the late John Brown.
