diagrams in illustration of this paper, and for assistance in carrying 

 out these researches; and to the following students for similar 

 help, namely : Messrs. W. Plant, W. G. Salt, and W. Scrivens. 



The authoritative naming of the fossils was essential, and to this 

 matter Dr. W. Hind and Mr. J. Ward have devoted much time and 

 trouble : it is due to these two geologists to acknowledge the 

 assistance derived from their pioneer-work in connection with the 

 palaeontology of the Worth Staffordshire Coalfield, which promises 

 results equally valuable when applied to the other British coalfields. 

 To the following experts my thanks are also tendered, for naming 

 fossils mentioned in this paper, namely : Dr. F. A. Bather, Mr. Gr. C. 

 Crick. Dr. A. H. Foord, Mr. B, Kidston, F.B.S., Mr. E. T. Newton, 

 F.B.S., Dr. A. S. Woodward, F.B.S., & Dr. Henrv Woodward, F.B.S.
