I'KOCEEDINGS OF TUE MALACOLOGICAL SOCIKTY. 



Mr. Fisher describes it as follows: — "My notes on the shell-deposit 

 in Harlton clunch-pit are very scanty. I send all that are relevant. 

 The deposit is a thin layer of sandj^ marl beneath the surface-soil. It 

 is not stratified, and is less than a foot thick. It appears to be a wash, 

 chiefly from the Boulder Clay that caps the hill. 1 have had some of 

 the stuff brought home, and washed it. It contains bits of flint and 

 chalk, brown clay, and fine sand, and a bit of pyrites. It rests upon 

 a disintegrated surface of clunch." 



The height is about 150 feet O.D. It would thus bo at a level 

 of about 60 feet higher than the deposit formerly described. From 

 a note made bj' Mr. Garrett at the time, it appears that above the 

 marl}^ band iu which the shells occurred there was from two to three 

 feet of surface soil. 



a, raiuwasli ; b, brown sandy clay with shells ; c, disintegrated clunch ; d, talus. 



The brown sandy clay with shells rests immediately on the weathered 

 surface of disintegrated clunch. 



(N.B. — There is onlj^ a small planed off fragment in the south-east 

 corner, as though the deposit in the southern (and higher) part had 

 suffered denudation.) 



I have visited this pit four times, twice under Mr. Fisher's guidance. 



List of species found: — Non-marine: Armi aUr'^ (Linn.) [6 granules, 

 one very large] ; Ilelicella itala (Linn.) ; Hygromia hispida (Linn.) ; 

 Vallonia pulrhella (Miill.) ; Pomatias elegans (Linn. ) ; Jaminia musconim ' 

 (Linn.). Marine : Ostrea edulis, Linn. ; Ifi/tilus edulis, Linn. 



The valve of Ostrea is much eroded, but the fragment of Mytilus is 

 quite bright, and the nacre sub -iridescent. As Harlton is an inland 

 village and parish, the occurrence of marine species in such a deposit 

 is decidedly of interest. 



Although there is no index forthcoming as to the age of this deposit, 



Procured at a recent visit (April 7th, I'JOG).
