1 " The Chinnor locality is in Oxfordshire. It is a pit on the Oxford Eoad, on the slope of Chinnor 

 Hill. The 'Lower Eock ' is the main mass of the Chalk-rock, probably the rock itself; for, although 

 there is a thinner bed of similar rock some fifteen feet higher, I think this upper bed is in the zone of 

 Micrasters. The section is ii very good one." — A. J. Jukes-Bkoavne. December 2Sth, 1889.
