INTRODUCTION. 



In this paper are set forth the results obtained by collecting 

 in the calcareous beds of the Bernician or Lower Carboniferous 

 series of Northumberland. The work, which occupied the 

 greater part of a year (1907-8), had for its object an inquiry 

 into the faunal succession of the Upper Bernician. 



The scheme adopted for zoning was that used by Dr. 

 Arthur Vaughan in his work on the Carboniferous Limestone 

 formation of the South-West Province, and successfully applied 

 by subsequent workers to other Carboniferous areas in Britain.
