■DEPOSITS OF THE SUSSEX COAST. 



35: 



that it would be difficult to give atiy but the most diagrammatic 

 section of them. The general succession seen on the foreshore on 

 the west side of the channel is : — 



Laminated peaty olay, with Corbicula, &c. 



Clayey gravel, with large flints, blocks of granite, &c. 



Eocene Clay. 



A short distance to the east we find : — 



Mass of rolled clay pebbles. 

 White marl with Chalk grains. 

 Clayey gravel with erratics. 



Still farther east the marl dies out, and peaty clay full of Corhicula 

 comes on again. The deposits here described are seen on the fore- 

 shore, but the low cliif above shows that the old beach-shingle 

 extends right across the channel, and is overlain by stony loam. 



In the peaty clays overlying the gravel with re-deposited erratics 

 were found several hones. of lihinoceros. Between and around the 

 bones were seen numerous land and freshwater shells and seeds of 

 plants. So that there might be no doubt as to the contemporaneity 

 of the different fossils, a large sample of the peaty and sandy clay 

 was taken from the same spot where the bones were found. The 

 material, after washing and picking over, yielded a large series of 

 shells and plants ; and, as this is the first case in which any consider- 

 able number of plants has been found in this country associated 

 with Pleistocene mammalia and moUusca, I give the complete list of 

 these classes, leaving the coleoptera and entomostraca for future 

 work. Por the determination of the mosses I am indebted to my 

 friend Mr. A. Gepp.
