193 THE GEOLOGICAL STRUCTUEE OF THE 



" Coralline beds." Several species of corals have been 

 obtained from tbese deposits, as well as many specimens of 

 Zeilleria Waltoni, and, less plentifully, Aulacothyris cariuata, 

 Bhynchonella pUcatella, Bh. suhtetraedra ; and, from the same 

 bed elsewhere, Acantlwthyris ijanacantliina rarely. 



Attention must now be directed to the south-western por- 

 tion of the Hill, where the upper beds may again be seen. 



There are two exposures southward from Dundry church: 

 one is Barns Batch quarry, at the bend in the road to Little- 

 ton on the south flank of the hill, and the other is about two 

 fields eastward in a small clump of trees. On the 6-inch 

 Ordnance map it was marked as a " gravel pit"; we have 

 called it "Barns Batch Spinney."
