v.— PLEISTOCENE SHELLS FROM COPFOBD, 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.
