Buckmani-gvit. 5. 'The Buckrmni - marl.' Yellowish 



and purplish, arenaceous, sticky, 



shelly marl, with Terebratula Buck- 



inani towards the lower part ; also 



Acanthothyris, globose species 1 



6. Hard, yellow, sandy limestone. The 

 lower bed — ' the Serpula-bed ' — 

 with S. socialis (?) abundant, and 

 two or three other species. A few 

 GryphacB also in it 2 6

Lower Tri- 7. Yellowish, slightly ironshot stone, 



gonia-gvit. very crumbly, especially when 

 much exposed ; harder and softer 

 layers. Occasional Gryphmm. Nu- 

 merous lamellibranchiata 3 5 



8. Hard band similar to the above, 



Pseudomelania 8 



9. The Meriani-bed. Rather browner, 



soft marl. Aulacothyris Meriani 

 fairly common along this line. 

 Terebratula cf. cortonensis, Bhyn- 

 chonella, sp 4 



10. Stone similar to 8 7 



11. Crumbly, calcareous, earthy marl ... 6 



12. Earthy, calcareous stone 3

Harford Sands 13. Yellow, brown, and blue, somewhat 



equivalent. sandy clay 8 



14. Blue, somewhat sandy clay, shell- 

 fragments (Ostrees?) 10

Upper Free- 15. Grey, disintegrated oolitic debris ... 3 



stone. 



16. Slightly pinkish, somewhat lami- 



nated, oolitic stone. Numerous 

 Ostrees, Pectens, and other lamelli- 

 branchiata, but all considerably 

 crushed. 



17. White, oolitic freestone. 



It may be noticed that the Clay-bed at the base of the Lower 

 Trigonia-grit is assumed to represent the Harford Sands, 2 and is 

 really first noticeable at the eastern end of Charlton Common, 

 though about 2 inches of it may be seen at Leckhampton Hill (see 

 Section XVII., p, 410). There is a distinct increase in the thick- 

 ness of the Notgrove Freestone. 



About | mile farther east is the uext section, Wistley Hill. 

 From the details of the section, especially beds 8 and 9, there can 

 be no doubt that this is the section called by Wright and others 

 ' Eavensgate,' 3 a name that I have used in various papers. However, 



1 This was measured at the eastern end of the north flank. About 300 yards 

 to the west only 3 inches of clay was found, overlain by 7 feet of Lower 

 Trigonia-grit, Aulacothyris Meriani being 2 feet 6 inches up.
