XXXI. — The Fossil Plants of th,e Carboniferous Bocks of Canonbie, Dumfriesshire, 

 and of Parts of Cumberland and Northumberland . By Robert Kidston, 

 F.R.S.L. & E., F.G.S. (With Five Plates.) 



(Read June 15, 1903. Issued separately December 7, 1903.) 



This communication deals with the fossil plants of the Calciferous Sandstone 

 Series and Carboniferous Limestone Series of Eskdale and Liddesdale ; of the Lower 

 Coal Measures of Canonbie ; of the Middle Coal Measures of Byre Burn, Canonbie ; 

 and of the Upper Coal Measures, Jockie's Syke, Cumberland ; to which is added a list of 

 the fossil plants of the Calciferous Sandstone Series of Cumberland and Northumber- 

 land, with the object of comparing them with those from the corresponding series in 

 Scotland. 



The geological structure of the areas from which the fossil plants were derived has 

 been fully described by Dr John Horne, F.R.S., and Dr B. N. Peach, F.R.S.* It is 

 therefore unnecessary for me to make any remarks on this part of the subject, so I have 

 restricted my geological notes to a bare statement of the horizons of the localities from 

 which the plants were collected. 



I must here express my thanks and great indebtedness to Mr J. J. H. Teall, F.R.S., 

 Director of the Geological Survey of the United Kingdom, for permission to use the 

 Collections of Plants made by the Geological Survey. I wish also to acknowledge 

 the valuable assistance I received from Mr A. Macconochie, by whom the greater 

 portion of the specimens were collected on the Scotch side of the Border, and to Mr 

 John Rhodes, of the Geological Survey of England, who collected almost all the 

 specimens from the Lower Carboniferous Rocks of Cumberland and Northumberland. 



I am also indebted to the late Mr Hugh Miller, F.R.S.E., for my knowledge of 

 some of the horizons of the Lower Carboniferous Plants from Cumberland and 

 Northumberland, and to Dr Horne and Dr Peach for the horizons of the Plants 

 from the Lower Carboniferous of Dumfriesshire. 



For the Lower Carboniferous Rocks of Berwickshire and some other districts which 

 are included in the paper by Dr Horne and Dr Peach I have not given lists of 

 the fossil plants, as these are reserved for another occasion.

 Eskdale and Liddesdale. 



The great part of the specimens on which the list of the fossil plants of the 

 Calciferous Sandstone Series of Eskdale and Liddesdale is founded was collected by
