No. 22. Greenish tenacious clay ; rises on the shore near 

 Barton Station, and runs out of the cliff near High Cliff Castle. 

 It contains a few shells, and the teeth and bones of fishes, and 

 measures about 20 feet. 



No. 23. The High Cliff sands and clays rise on the shore a 

 quarter of a mile to the eastward of Chuton Bunny, and run out of 

 the cliff about a quarter of a mile to the westward of High Cliff 

 Castle. This bed is composed of alternations of sand and clay, 

 of brown, green, and ferruginous colours. It is very rich in 

 beautiful shells, as Cassidaria coronata, C. carinata, with many 

 other species, and contains numerous nodular masses made up 

 entirely of fossils, but my materials do not at present enable me 

 to give a correct list of these. This bed attains a thickness of 

 from 20 to 30 feet. 



No. 24. Green clay; rises on the shore at Chuton Bunny, and 



* The British Natural History Society, of which Mr. Charlesworth of 

 York is Secretary, has distributed amongst its members a very complete 

 suite of the fossils of the above lists. A series of these shells, including 

 100 species, is supplied for a small subscription.
