834 APPENDIX. 



Sixty yards above the Kilburn Coal. — Between the Blackshale Coal 

 and the Kilburn Coal exposures are scarce. A brick pit at the Albany, 

 north of Stapleford, shows a thin coal about 60 yards above the Kilburn 

 Coal. From the ironstone nodules in the black shales overlying the 

 coal the following mollusca have been obtained : — 



Naiadites modiolaris (Sow.). 

 Carbonioola aquilina (Sow.). 

 „ robusta (Sow.). 



In addition, a solitary scale of Coelacanthus elegans (Newb.) was 

 found. The floor of the brick pit is a very hard, massive, ripple- 

 marked bed of ganister-like sandstone containing numerous specimens 

 of Carbonicola aquilina. This is the first occasion known to the writer 

 of the occurrence of the mud-loving genus Carbonicola in an arena- 

 ceous rock. 



Kilburn Coal. — The Survey record a fish-bed from the roof of this 

 coal at the Denby Colliery. 



At the Horsley, Dale Abbey, Stanley, and Mapperley Collieries the 

 black roof shales of this coal also contain fish remains. The list, 

 which is still incomplete, includes the following: — 



Megalichthys Hibberli (Agass.). 

 Rhizodopsis sauroides (Willm.). 

 Sphenacanthus hybodoides (Egert.). 

 Acanihodcs Wardi (Egert.). 

 Elonichthys Egertoni (Egert.). 

 Coelacanthus elegans (Newb.). 



At the Trowell Moor Colliery a few shells occur, including: — 



Carbonicola sim'ilis. 

 Naiadites modiolaris. 



The specimens of C. similis are identical in condition and size with 

 those recorded from the Top Hard Coal. 



The roof shales of the Kilburn Coal in the new sinking at Loscoe 

 Colliery, near Heanor, yielded a number of shells, including: — 



Carbonicola robusta (Sow.). 

 „ aquilina (Sow.). 



Honeycroft Ralce. — In the Stanton district, on the outcrop of the 

 Kilburn Coal, the abandoned open-cast workings in this rake contain 

 specimens of Carbonicola robusta (Sow.). 



The roof shales of the Trowell Moor Colliery yielded the following 

 plants :- — 



Catamites cistii (Brongn.). 



„ ramosus (Artis). 



„ sp. (external surface). 

 Sphenophyllum cuneifolium (Sternb.)- 

 Alethopteris lonchitica (Schl.). 

 Mariopteris lali folia (Brongn.). 



sp. 

 Neuropterts heterophylla (Brongn.). 



„ obliqua (Brongn.). 



Aphlebia crispa (Gutbier). 

 Lepidophyllum lancifolius (Lesq.). 

 Stigmaria ficoides. 

 Pinnularia, sp.
