Vol. 59.] FOSSIL PLOKA OF THE CXJMBEELAND COALFIELD. 5 



The remaining locality from which plant-remains were collected 

 by me is the coal of the Senhouse High Band, at the Ellen - 

 borough Colliery, south of Maryport. This seam of coal, which 

 is here of workable thickness, contains numerous impressions of 

 Sigillaria and Stigmaria. It belongs to the Sandstone Series. 1 



No other plants from the Sandstone Series are apparently to be 

 found in any museum or private collection, apart from those above 

 mentioned in the Woodwardian Museum. I have made many 

 enquiries for specimens in the museums in the North of England, 

 and in London, and also of nearly all those who from time to time 

 have studied the Carboniferous rocks in this district. Several 

 geologists 2 were aware that such plant-remains had been found, 

 but were unable to give particulars of the whereabouts of any 

 specimens.

Calamitean pith-casts are very common fossils in the Sandstone 

 Series of Whitehaven, and among the specimens in Sedgwick's 

 Collection some are exceedingly well preserved. The cast of 

 G. approximatus, part of which is figured on PI. I, fig. 3, is 4 inches 

 long, and 2\ inches across. There are eight small internodes, each 

 about a quarter of an inch long, succeeded by a larger internode, 

 | inch in length. The latter bears a row of branch-scars, some of 

 which are seen distinctly in the photograph. Other specimens show 

 twelve small internodes, of approximately equal length, between the 

 larger internodes bearing the branch-scars.

3 The full synonymy, previous to 1886, will be found in most cases in 

 Kidston's Catalogue of Palaeozoic Plants in the British Museum. Only the 

 more recent references, and some of the best-known works in which the species 

 are figured, are mentioned here.
