882 J. E. MARE ON LIFE-ZONES OP THE 



The Brathay Flags, as before mentioned, are well exposed in 

 Brathay quarry. The Lower Coldwell Beds form a marked feature 

 across the country, although not exposed in any large quarry. The 

 Middle Coldwell Beds are seen in many quarries, notably Coldwell 

 and Randy Pike ; whilst the Upper beds are excellently shown, and 

 fairly fossiliferous, in a quarry about 200 yards south of Coldwell 

 quarry. 



The Brathay Flags, when traced across the country, become 

 thicker towards the S.W., whereas when we trace them eastward 

 they become very thin. The Coldwell Beds also alter in the same way, 

 and the lowest subdivision of them dies out between Troutbeck and 

 Kentmere, the other divisions being persistent. 



The following is a list of the fossils of these beds in this part of 

 the district : — 



Fossils of the Brathay Flags. 



Favosites aspera Stockdale. 



Monograptus priodon Stockdale ; Nanny Lane, Troutbeck ; 



Brathay Quarry. 



Cyrtograptus Nanny Lane. 



Retiolites Geinitzianus, Barr Stockdale. 



Crinoid Nanny Lane. 



Orthoceras Stockdale. 



All these fossils occur near the base of the Flags ; and G. priodon, 

 in a very good state of preservation, is very characteristic of this 

 division of the Flags.
