310 English Jurassic Foraminifera. 



2. Kellaways Rock ; sandy clay and sandrock ; very shelly in places. Dogs- 

 thorpe brickyard.

4. Great Oolite Clays, 20 feet ; dark-blue and greenish clays, with shelly bands. 

 New England brickyard, Orton railway-cutting, and in many wells. 



5- Great Oolite Limestone, 25 feet ; with marly or clayey bands and partings,

 In many parts of the neighbouring Pens may be found the 

 '•'buttery clay," of Pliocene or Sub-recent date, from which one of 

 us long ago obtained and determined many interesting Foraminifera ; 

 see Mr. H. B. Brady's memoir on Estuarine Foraminifera in the 

 Annals Nat. Hist. 4, vi. pp. 305-6.
