CULPIN : MARINE AND OTHER FOSSILS. 
The marine shells at Bentley, which numbered 38 species, 
were found in four bands, the comparison with Brodsworth 
(21 species), in regard to positions, being as under : —

Of the freshwater shells, Anthracomya Phillipsi was found 
in abundance at one level near the top of the Coal Measures, 
and sparsely some 100 feet above the Barnsley Coal. The 
experience, so far, in sinkings and borings in the Doncaster 
district, is that its occurrence in large numbers is confined to 
the higher beds of the Coal Measures. What may prove to be 
a new species of Anthracomya has been obtained by Mr. H. T. 
Foster from the roof of the Duncil seam, about 50 feet below 
the Barnsley Coal. It appears to be a descendant of A. Adamsi. 
There was a prolific bed of plant remains about 125 feet 
above the Shafton Coal, and as the list shows, plants were 
numerous at several positions in the beds from 320 feet above the 
Barnsley seam until the coal itself was reached. 
Fish fragments were found at various depths, but mainly 
in or near the marine bands. Listracanthus Wardi was obtained 
by Dr. Walcot Gibson from the principal marine band, which 
is the one with the limestone base, about 700 feet above the 
Barnsley Coal. 
Thanks are due, and are hereby given, to Dr. Wheelton 
Hind, Dr. Edgar D. Wellburn, and Dr. R. Kidston for examining 
and naming the fossils. Also to Mr. R. Clive and Mr. H. T. 
Foster, of the Bentley Colliery, for facilities and assistance 
given in the examination of the material tipped and its verification 
in the shafts.
