Vol. 59.] FOSSIL FLOKA OF THE CTTMBEELAND COALFIELD. 11 



the ' Cannel Band.' The ' Bannock Band,' another important seam, 

 lies about 135 feet above the Main Band at Whitehaven, and is 

 there 7 to 8 feet thick. The ' Six Quarters Coal ' at Whitehaven is 

 about 255 feet below the Main Band, and 7j feet thick. 



(1) Localities and Horizons of Plant-Itemains. 



Fossil plants do not appear to be so abundant in the Cumberland 

 Coalfield as in some other coalfields. The finest plants collected 

 were from the Cannel Band in the Kobin Hood Pit at Flimby, south 

 of Maryport, belonging to the Flimby & Broughton-Moor Coal 

 Company. I am indebted to Mr. Lloyd Wilson, of the above 

 Company, for special facilities for obtaining this collection. The 

 plants occur there in the shales forming the roof of the Cannel 

 Coal, from 3 inches to 2 feet above the seam. This band is believed 

 to lie about 380 feet below the Sandstone Series. 1 



I also obtained plants from the shales above the Main Band at 

 Walk Mill Pit, Moresby, rather more than 2 miles east of White- 

 haven. A few specimens, from the same horizon in the William 

 Pit at Whitehaven, were forwarded to me by the kindness of the 

 manager, Mr. Turner. 



All the plants from the Productive Series are thus from the 

 horizon of the Main Band, which, as will be shown, belongs to the 

 Upper Division of the Productive Measures. Attempts have been 

 made to obtain specimens from the Bannock Band, and especially 

 from seams below the Main Band, but without success. 



So far as I am aware, with the exception of a few specimens at 

 Keswick and Oxford, mostly without record of horizons, no collec- 

 tion from the Productive Measures of Cumberland is to be found in 

 any museum. The only specimens that have been described and 

 figured from the Whitehaven Coalfield are Lindley & Hutton's 

 Splienopteris crenata and Schizopteris adnascens 2 ; the types of these 

 are in the Museum of the Northumberland & Durham Natural 

 History Society at Newcastle-on-Tyne. Mr. Kidston has shown 

 that both Lindley & Hutton's species belong to Pecopteris (Dactylo- 

 theca) plumosa, Art. 3
