90 PROCEEDINGS COTTESWOLD CLUB 1910 



Coming now to the western face of the hills, in the lane 

 from North Stoke to Bitton, is the section that was recorded 

 by Prof. S. H. Reynolds and Dr A. Vaughan,' on the authority 

 of Mr S. S. Buckman. It is at the top of the lane in which 

 Charles Moore found what he thought might be a thin repre- 

 sentative of the Marlstone.^ It is unnecessary to recapitulate 

 here all the details that have been given by Prof. Reynolds and 

 Dr Vaughan ; it will suffice to say that they record that the 

 Upper Trigonia-Gnt rests upon sands and sandstones of 

 Duniortierice-striatuli hemerae. 



In the road-side near the schools at Upper Cheney, there 

 is an exposure of much-disturbed rock ; but the sequence ap- 

 pears to be as follows : 



Sequence at Upton Cheney 



III. Doulting Stone i.. Limestones, pale-yellowish oolitic. 



/ 2. Limestone, rubbly, somewhat ironshot, 

 with corals (principally near the top) ; 



IV. Upper Coral-Bed Ostrea sp., Trigonia costata, Sowerby, 



and Ctenostreon pectiniforme (Schlotheim), 



VI. Upper Trigonia- Terebratula globata, auctt. non Sow., and 



Grit a fragment of Polyplectites cf. lingniferns 



^ (d'Orbigny). 



Non-sequence : Bajocian and Aalenian wanting. 



r 3. Sandstone, hard, calcareous. (In a sand- 



Cotteswold pit on the right-hand side of the road, a 



Sands - short distance to the cast, is seen a con- 



I sidcrable thickness of yellow, micaceous 



V sands with " sand-burrs.") 



Although no definite indications of the Cephalopod-Bed 

 occur in this section, deposits of the hemerae ? aalensis, Moorei, 

 DumortiericB and dispansi, have been observed in the neigh- 

 bourhood.^ The record of Polyplectites is particularly interest- 

 ing, in that this ammonite occurs at the base of the deposit of 

 Truellei date in Normandy, and there gives its name to a bed 

 {"Linguiferus-Bed ") that immediately overlies the Garantiana- 

 Bed." 



The top-portion of the Anahacia-lAvaesiorxes — of which 

 the uppermost layer is considerably bored — with the overlying 

 Rubbly Beds (similar to those at Twerton Hill), is seen in an 

 old quarry in the corner of a field east of the road at Tog-Hill 

 Farm.
