﻿CONCLUSION. 



125 



the limestone is a group of Biachiopoda, agreeing closely with that of Lununaton, 

 Woolborough, and the Upper Dartington beds, of a very limited thickness, among which 

 Ehynchonella triloba, Rh. cuboides, and Merisla plebeia, &c, are conspicuous. 



Dartington, near Totness, is a very important locality for Brachiopoda; but 

 Mr. Champernowne is of opinion that in the immediate neighbourhood of the 

 Dartington limestone there are no beds to be seen on the level of the Ogwell shales. 

 Hope's Nose is a very interesting locality, and the beds there do not (as far as fossils are 

 concerned) seem to be on a very different level from the Woolborough level : we cannot, 

 I think, be very far wrong if we assign their position to the passage-beds between the 

 limestone and shales and slates above. 



Land's End, near Torquay, appears to be a spot worthy of further examination. 

 Mr. Champernowne writes me : " In a cove on the east side of the point known as the 

 Land's End, I have recently discovered beds of shales or impure limestone, in which 

 I have found Orthis arcuata, Atrypa reticularis, A. lens, Rhi/nchonclla bifera, Rh. pro- 

 tracta, and some other species. Mr. Champernowne, who has devoted much attention 

 to the Middle Devonian formation of Devonshire, sends me the following scheme of their 

 probable correlation : 



Newton. 



Dartington. 



Torquay. 



Plymouth. 







Hope's Nose. 



Luramaton and Bar- 

 ton.* 



Shales with 0. arcuata 

 (Mutton Cove). 



Mount Wise, lower 

 part of Plymouth 

 Limestone. 



Woolborough. 

 Bradley.

 mites. 



Skinner's B. Quarry 



Meadfoot (base of 

 Limestone). 









West Ogwell and Chir- 

 combe Bridge Shales. 





Meadfoot Shales and 

 Sandstone. 



Purple and Grey Slates 

 (without fossils). 



* The intermediate parts are seen in many places dipping away from the Torquay anticlinal, but 

 Mr. Champernowne has thought necessary only to indicate the well-marked Lummaton horizon and the 

 base.
