 Q.J.G.S., vol. xlv., 1889, p. 445. 



Near the Monument on Nibley Knoll, which is such a 

 land-mark, is a quarry in which the Upper Coral-Bed is very 

 well displayed : better so than anywhere else in the South 

 Cotteswolds, with the exception of Rodborough Hill. The 

 section was noticed by Mr S. S. Buckman, but he simply 

 recorded that the " Upper Trigonia-Gvit " overlies the Freestone, 

 which in turn succeeds to beds which he refers with a query to 

 D', that is, to the " Sandy ferruginous beds " of Witchell.^ He 

 gives, however, a detailed account of the " Opalinwn-Zone," 

 Cephalopod-Bed, and Cotteswold Sands, which are exposed at 

 the top of the bank by the lane-side between the quarry and 

 North-Nibley village. This account is amphfied in a paper 

 pubUshed by the same author in 1889, the Freestone being re- 

 ferred to the " Murchisonce-Zone" ; while the Upper Lias 

 deposits are more minutely subdivided.^ Mr H. B. Woodward 

 gives a record of the beds exposed in the quarry ; but only 

 makes two subdivisions — Ragstones and Freestones ; while he 

 publishes a summary of Mr Buckman's record of the beds in 

 the lane-section."*
