Of these the most interesting are : — 



The single specimen of Zonitoides exr.avatus, the species not having 

 been found in the fossil state south of the Thames, although it occurs 

 in the Holocene of Chignal and the Pleistocenes of Copford and Clacton in 

 Essex. 



Vitrea Rogersi, also represented by a single example, because it confirms 

 the existence of this species in Holocene times. Some examples were 

 found in the Ightham lissure, but there being at the time some doubt 

 whether they might not have been introduced accidentally from above, 

 attention was not specially drawn to them. 



Clausilia hiplicata is also noteworthy, it having hitherto only been met 

 with in Holocene deposits at Blackfriars and at Reigate. The striation on 

 th'« Sj^)ecimen is less marked than on recent examples, an unusual con- 

 dii^ion, since sculpturing is usually more conspicuous on fossil than on 

 recent shells of the same species. 



A small snail's egg which was found is probably that of a Clausilia ; 

 while the fragment of a larger one may be put down to Helix nemoralis. 



The specimens have now been deposited in the British Museum. 



I am indebted to Mr. B. B. Woodward and Mr. A. S. Kennard for their 

 kindness in determining and describing these specimens, also for the 

 information as to former finds, etc.
