226 PROCEEDINGS COTTESWOLD CLUB 191 1 



This section has been briefly described by Hudleston' and 

 the top-bed of the above record corresponds to his bed A ; 19 

 and 20 to his bed B, together with his " variable hne of loose 

 reddish sand"; and the top-layer of the Chipping-Norton Lime- 

 stone to his bed C. Mr H. B. Woodward has also given a record/ 

 which in the main, agrees with the above ; but he records the 

 remains of Cetiosaurus^ from the deposit in his section that 

 corresponds to beds 19 and 20 in the above record. 



The Chipping-Norton Limestone is well displayed in a 

 quarry near the Workhouse (53) and has been worked at Over 

 Norton and other places in the immediate neighbourhood. It 

 is poorly exposed at the top of the bank in the deep cutting 



(55) on the way to Langton Bridge, where Windoes identified 

 the Clypeus-Gni " and the probable equivalents of [Walford's 

 blocks] C and D " below it.''

(56) has been described in detail by T. Beesley ? a somewhat 

 clearer record has been published by Hudleston f and addi- 

 tional details have been given by Mr Walford (pp. 15-16).^
