The Carboniferous Succession below the Coal- Measures. 397 



The actual top of tbe quarry, wbere the bods wero mucli weathered, 

 was characterised by the presence of corals of diagnostic importance, 

 viz, : — 



Cyalhaxonia aff. liimhiana, Vaugliau. 

 Lithoslrotion irreyulare (I'hill.). 

 L'insdaleia Jloriformis (Flem.) . 

 L. ruyosa, M'Coy. 



Here again, in even greater ninnl)er8 than at Gorsedd and IIollo- 

 way, were Prodacti of tbe largest size. The full list fi'oin this 

 quarry is as follows : —

(xxi) The most important sections of Carboniferous Limestone in 

 tbe district around Mold are confined to the hilly range extending 

 from Hendre to near Llanferres. At the former place tliere are two 

 quarries in tbe liiriestone at the same horizon. Since that on tbe 

 north side of the road exhibits more of a sequence, its individual 

 beds were more carefully worked. In tbe following section tbe 

 jmrticulars given by Mr. A. Straban, F.K.S., in tbe Geological 

 Memoir of Flint, Mold, and Ruthin, p. 39, are adopted : — 



7. Sandstone 



6. Shale 



5. Line of grit ... 



4. Massive Coralline Limestone 



3. Thin-bedded Coralline Limestone 



2. Limestone and shale... 



1. Limestone 

 No. 1 (limestone) contains CyathoyhjUum reginm, Phill. 

 No. 2 (limestone and shale) contains — 

 Fistnlipora aff. incrustans, N. & T. Seminula nmbigun (Sow.). 



(Vaughan). /Spirifer cf. ditplicicosUitun, Piiill. 



Athyris pkaiosulcata, Phill. S/nnfrrina biplicata, Dav. 



Proditctns lonyispimis. Sow. £uomphalus sp. 



Khipidomella Michelini (L'Eveille).
