Notes. — Some 20 feet lower down the hill is an exposure of what look like 

 Harford Sands, near the bench-mark 920, on the right-hand side of the road 

 to Winchcombe. There is an undoubted exposure of these sands in a rabbit- 

 burrow, in the copse under the steep brow of the hill to the left. This is at 

 about the same level. The sandstone is crowded with lamellibranchs. A 

 measurement makes it 45 feet below the Notgrove Freestone. About another 

 25 feet lower is an exposure of Oolite-Marl with Terebratula fimbria. 



In the main, the strata at Farmcott and Sudeley Hill correspond 

 with the Cleeve-Hill and Mid-Cotteswold sections, but the lithie 

 character of the Lower Trigonia-giit has altered somewhat. The 

 horizon with Terebratula TJptoni is very useful :^or comparison with 

 Leckhampton Hill, and gives a datum-line at once. Belemnites 

 gingensis is also a good fossil by which to distinguish a particular 

 horizon. 



It may be noticed that we have lost the Phillipsiana to Wit- 

 c^gZZia-beds found at Cleeve Hill 3| miles to the west. Their limits 

 can be very precisely defined. Thus at Cotehay Farm the top layer 

 of the Bourguetia-hedi^ is bored — the Philli^siana-beds have gone. 

 At Rowell Gate the Notgrove Freestone is bored : the Bourguetia- 

 and Witchellia-hQdi^, therefore, disappeared in the Charlton Abbots 

 Valley. 



In the next sections the lithie character of the Lower Trigonia- 

 grit is altered entirely ; but Hyperlioceras defines the horizon. 

 These sections carry the strata farther down, and show the 

 sequence.
