742 MR ROBERT KIDSTON ON THE FOSSIL PLANTS OF 



Mr A. Macconochie, of the Geological Survey of Scotland, about twenty years ago, 

 and on these I contributed a paper to this Society in 1883, # and to Mr Macconochie, 

 I believe, is also due the credit of discovering all the localities from which fossil plants 

 have been collected from this series in Dumfriesshire. 



After the publication of my paper dealing with the Eskdale and Liddesdale 

 fossil plants, some of Mr Macconochie's localities were visited by other collectors and a 

 few specimens collected by Mr T. Stock, and a larger series, which was acquired by the 

 Geological Department of the British Museum, from Glencartholm, were subsequently 

 examined by me. The present list contains the results of all these collections, and I 

 take this opportunity of correcting one or two of my earlier identifications which 

 further investigation has shown to be inaccurate. 



To save repetition, I give here a list of all the localities and horizons from which the 

 specimens have been derived, as in the appended list of species the localities are given 

 in a contracted form and the horizons are not stated, as at no one locality have the 

 fossil plants been collected from more than one horizon. 



I. Locality. — Bank of River Esk, Glencartholm, Eskdale. 



Horizon. — " Carbonaceous Series " ( = " Scremerston Series ").+ 

 IT. Locality. — Foot of Tarras Water, three miles south of Langham, Eskdale.

 many feet below the base of the Fell Sandstones.
