PLANTS. 



The following plants were obtained from this horizon : — 



Colliery. 

 Catamites variant: (Sternb.), Gedling 



„ cisli (Brongn.), 

 sp. 

 Neuroptens obliqua (Brongn.), 



sp. 

 Lepidophloios laricinus (Sternb.), 

 Lepidodendron obovatum (Sternb.), 



,, lycopodioides (Sternb.), 



„ ophiurus (Brongn.), 



,, dichotomum (Sternb.), 



Lepidostrobus, sp. 

 Sigillaria laevigata (Brongn.), 

 „ ovata (Sauveur), 



Specimens of Lepidodendron are the only common plants at this 

 horizon. 



Top Hard Coal (Barnsley Bed). — In discussing the molluscan 

 assemblage found in association with this seam an experimental area 

 of about 40 square miles will be considered ; its boundaries are fixed on 

 the west by the almost continuous outcrop of the coal from Wollaton, 

 near Nottingham, to Pinxton, a distance of ten miles, and on the east 

 by the line of collieries from Gedling up the Leen Valley to Annesley. 

 Within this area the fossil horizon has been detected in the three good 

 exposures on the outcrop of the seam : — 



Digby clay pits. Levd at Brookhill Leys. 



Clay pit at Stoney Lane, Brinsley. 



and also at the following eight collieries: — 



Gedling. Annesley. 



Bestwood. Bulwell. 



Hucknall Torkard. New Watnall. 



Newstead. High Park. 



There is thus every reason to infer that this fossil horizon extends 

 continuously throughout and beyond the area under consideration. 

 The following general section of the roof of the Top Hard Coal illus- 

 trates the mode of occurrence of the fossils : — 



Grey shale with bands and nodules of ironstone, numerous shells. 

 Combe Coal. 



Underclay (clunch) passing laterally into shale with shells. 

 Top Hard Coal. 



The following lists enumerate the fossils from this horizon: — 



MOLLUSC A. 



Naiadites modiolaris (Sow.). Carbonicola aquilina (Sow.). 



,, carinata (Sow.). ,, similis (Brownl. 



„ triangularis (Sow.). ,, nucularis (Hind.). 



,, quadrata (Sow.). Anthracomya modiolaris (Sow.). 



„ Williamsoni (Brown). 



FISH. 

 Coelacanthus elegans (Newb.), a solitary scale ; Gedling Colliery.
