IV.— PLEISTOCENE NON-MARINE MOLLUSC A FROM 

 CLACTON-ON-SEA, ESSEX. 



By Wilfred Mark Wbbb, F.L.S., Memb. Malac. Soc. 



In the Essex Naturalist some years ago' the present 

 writer dealt with a number of Pleistocene shells from a locality 

 presumed to be some miles from Walton-on-Naze"" and found by 

 the late John Brown, F.G.S., of Stan way. More recently^ it had 

 to be admitted that this locality was one and the same with 

 Clacton, whence Brown also described shells of like age. The 

 first mentioned specimens being in the possession of the Essex 

 Field Club, a list was given in detail. Since then however, the 

 presentation of further specimens as noted below, and the 

 alteration in the locality, has rendered it advisable that a corrected 

 list should be made out. The present Note further verifies one or 

 two records of the older writers upon whose authority, up to the 

 present time, they solely rested, as none of the species in question 

 could be traced. 



The specimens marked " J.W.K." form part of the small 

 collection of Pleistocene remains from Clacton, presented to the 

 Club by the Rev. J. W. Kenworthy, (see Essex Nat. vol. x. p. 

 406) and those marked " W.H.D." formed part of the collection 

 of Mr. W. H. Dalton, F.G.S., recently presented to the Club, 

 [both of which collections will be more fully described in a future 

 *' Museum Note." — Ed.] The specimens without initials formed 

 part of the original "John Brown Collection."
