Carhonicola {Anthracosia) nucularis. 



This species is recorded by Dr. Hind in his Monog. on 

 Carhonicola, &c. (p. 63 and p. 159), as occurring- in the 

 Lower Mountain Mine, Wigan. 



Carhonicola [Anthracosia) aquilina. 



This species is essentially the Carhonicola of the Lanca- 

 shire Lower Coal Measures. It occurs in vast numbers in 

 the shale immediately overlying the Bassey or Salts mine at 

 Oreave and Oaken Cloughs, near Bacup. It also occurs at 

 Grime Bridge Clough. Specimens from Oaken Clough are 

 in the Dugdale Collection, M.M. 



Also at Helpet Edge, Saddle worth. Specimens are mostly 

 in the form of internal and external casts. The species must 

 have covered large banks of mud judging from its abundance 

 at the localities named, it also ranges upwards to the shales 

 under the Upper Mountain Mine. Carhonicola aquilina is 

 probably the species recorded by C. Dugdale from his JN^o. 6 

 bed of the Lower Coal Measures. (C. Dugdale, Trans. Man. 

 Geol. Soc, Yol. XIX.) 



Associated with C. acuta and C. robusta above Shale Bed ^ 

 coal (Bassey or Salts seam) at Rishton Colliery, near 

 Blackburn. 



Above the 40 yards or Upper Mountain Mine associated 

 with C. acuta, Anthracomya Williamsoni, and A. Wardi at 

 Burrs, half-a-mile north of Bury. . .-■ 



Carhonicola (Anthracosiaj sp. 



Over Mountain Four Feet Seam at Carre Heys, Colne. 

 (W. 658 e coll.. Wild, M.M.) 



Anthracomya Williamsoni. 



This species is recorded by Dr. Wheelton Hind from the 

 Upper Mountain Mine, Burrs, half-a-mile north of Bury.
