From this list it will be seen that five species of Foraminifera 

 belong to Lower Bernicean rocks, eight to the Upper, and that 

 seventeen species range from the Lower to the Upper, and these are 

 among the most common of the Carboniferous Foraminifera, some of 

 them having a very wide geographical distribution. In the following 

 notes, however, some of the species marked only Lower Bernicean 

 in the list, I have found in the Upper or Yoredale Shales both of 

 Northumberland and North Lancashire. 



In the Monograph of Carboniferous and Permian Foraminifera of 

 Mr. Brady, the classification of the species differs from that adopted 

 by Prof T. Rupert Jones, F.R.S., in the Catalogue of Fossil 

 Foraminifera in the collection of the British Museum (1882). This 

 work may be obtained from the Trustees, through any bookseller, 

 and the student of fossil foraminifera will find it to be a very useful 

 hand-book. In following this classification then, it must not be 

 premised that I do so out of any desire to place myself on a level 

 with, or in opposition to, specialists like Prof T. Rupert Jones or 

 Mr. H. B. Brady. I accept the arrangement because it is a later 

 production than that of the monograph, and Mr. Jones says that it is 

 adapted from the table in Mr. H. B. Brady's ' Notes on Reticularian 

 Rhizopoda ' (Quart. Journ. Micro. Soc, N. S., Vol. xxi.).
