THE COIULUAN KOCKS OF ENGLAND. 363 



Fig. 18. — General Section of Gorallian beds near Appleton, 



A. Alternations of hard oolitic limeatone and brash. 



B. Passage-beds, fossiliferous, 4-7 feet. 



C. Lower Calcareous Grit, upper beds. 



C. These are the highest beds of the Lower Calcareous Grit ; 

 about 14 feet are quarried. The actual thickness of the formation 

 here is uncertain ; but water is obtained at a moderate depth, and 

 there are springs on the escarpment facing the north. The beds 

 visible consist of alternations of soft buff and hard blue rock, which 

 are fairly fossiliferous, especially on approaching the next group. 

 These are the " freestone " and " flint " of the workmen. The 

 " flint," or hard blue, occurs in beds, and sometimes in doggers. 

 The top bed included in this series is pretty full of RliyncJionella 

 Thurmanni ; it sometimes presents the speckled appearance of the 

 next group. The Ammonites &c. lie mostly towards the upper 

 part ; the following are noted — Nautilus heccagonus, Ammonites 

 corclatus (excavatus), A. goliathus, A. plicatilis ? (A. perarmatus is 

 less common), Gryplwea clilatata, Glyphea rostrata, teeth of Plio- 

 saurus and Lamna ?, wood. Some of the Brachiopoda quoted in the 

 next series are also met with. 



B. Sandy speckled limestones of considerable hardness, varying 

 from buff to blue, and constituting a stone difficult to describe but 

 easily recognized. These are beds intermediate between the Lower 

 Calcareous Grit and the oolites, and represent, to a certain extent, 

 the passage-beds of the Tabular range. They are somewhat irre- 

 gularly developed, and vary in the different quarries. The fauna is 

 much the same as the top bed of calc-grit, but richer both in 

 individuals and species. In addition to some of the Ammonites 

 already quoted, the following may bo deemed characteristic : — 



Pecten fibrosus, Sow. 

 Avicula ovalis, Phil. 



expansa, Phil. 



Trigonia*, sp. n. 

 Waldheimia bucculenta, Sow. 

 Terebratula fileyensis, Walk. 



Ehynchonella Thurmanni, Voltz 

 Glyphea rostrata, Phil. 



scabrosa, Phil. 



Echinobrissus scutatus, Lam. 

 Millericrinus echinatus, Gold/. 



* A new scaphoid form remotely related to Trigonia recticosta, Lye, of the 

 Inferior oolite ; it occurs on the same horizon, associated with Waldheimia 

 Hucttestoni and Terebratula fileyensis, in the neighbourhood of Snainton.
