and the Upper Coal Measures, for they are only the upper and lower ends of a continuous 

 chain, but taking all the available evidence into consideration, we must class that portion 

 of the ' Red Shales ' which are met with at Jockie's Syke with the Upper Coal Measures. 

 The following are the localities from which the plants were collected in Jockie's 

 Syke, one mile east by north of Riddings Junction, Cumberland : — ■ 



A. Jockie's Syke. The original locality discovered by Mr Macconochie in 1879, 



the exact position of which cannot now be determined. 



B. Jockie's Syke. Streamlet entering on right of main stream, 30 yards south of 



North British Railway. In soft red and greenish shales. 



C. Jockie's Syke. Main stream in Syke, about 125 yards above railway. In purplish 



shale. 



D. Jockie's Syke. Main stream of Syke, about 300 yards above railway. In 



purplish clayey shale.
