CULPIN : MARINE AND OTHER FOSSILS. 
boulder clay, and also in similar boulders from a sinking 
at Bentley, near Doncaster, where glacial debris, 20 feet 
thick, was found below a covering of 80 feet of river silt 
and clay. 
Since these discoveries, a sinking has been successfully 
carried down to the Barnsley seam at Brodswortli, about four 
miles north-west of Doncaster, and as the result of watching 
the ground gone through (see Section, p. 333), some particulars 
have been obtained, which it is thought desirable to place on 
record, not only in regard to the range of Anthracomya Phillipsi 
and its allies, but also as to the existence of marine bands 
not hitherto recorded in Yorkshire. 
But before mentioning these further, I should remind my 
readers that at the Annual General Meeting of our Society at 
Shefheld, in November last, as also at the Annual Meeting of 
the Institution of Mining Engineers in the same city, in Sep- 
tember last, Mr. H. St. John Durnford recorded a marine band 
found 195 feet below the base of the Permian rocks in a deep 
boring at Barlow, near Selby (for account of this boring see 
pp. 337-346). Abundant fossil plants were found some 500 feet 
lower, and Carbonicola acuta and Anthracomya sp. occurred 
100 feet below the plants. Mr. Durnford further stated that a 
bed with marine fossils had been proved in a boring at 
Wentbridge. 
Mr. E. Hummel, of the Leeds University, has also been ex- 
amining the Coal Measures recently, and has collected data 
which, when published, will add -very considerably to our know- 
ledge of the marine bands, and other features, in the Yorkshire 
Coalfield. 
References to the fossils recorded in the publications men- 
tioned, with the exception of those announced by Mr. Durnford, 
have been entered on a table (p. 334) of the Measures above 
the Barnsley Coal, which has been copied from the Geological 
Survey Memoir on the Yorkshire Coalfield. Further lists 
(pp. 327-331) summarise the records from the Brodswortli 
sinking.
