96 PROCEEDINGS COTTESWOLD CLUB 1910 



Below the Scissum-Beds comes the Cephalopod-Bed. The 

 Moorei- and Dumortievia-Bed portion, of the usual richly- 

 ironshot and fossiliferous type, is to be seen in an opening 

 below the fine ancient earthwork on the hill above Little 

 Sodbury, and formerly was visible (with inferior beds) in the 

 deep lane above the same village. Now, however, this latter 

 section is quite overgrown, and it is necessary to rely upon the 

 details obtained and recorded by Mr Buckman,' and re-stated 

 — with certain emendations — in the generalized section given 

 on page 94.* 



Horton-Rectory Quarry. 



The section now under consideration is certainly one 

 of the most interesting in the South Cotteswolds, affording as 

 it does a view of the beds in an area none too rich in 

 exposures. The Fullers' Earth, Rubbly Beds, and the top- 

 portion of the Anabacia-UiTCiQsiones have been removed by 

 denudation, but there is a considerable thickness of the last- 

 named subdivision still remaining. Holl identified it with his 

 "Upper Ragstone,'"* and Edwin Witchell with his "White 

 OoUte."^ When I use the term " White Oolite " henceforth in 

 this paper I mean rock on the same horizon as this Horton 

 " White Oolite," because it is by no means certain that the 

 white-coloured limestones of various localities that Witchell 

 called " White Oolite " are of precisely the same age. 



The thick-bedded limestones between the conspicuous 

 White Oolite and the fossiliferous Upper Trigonia-Gx'ii corre- 

 spond to the Doulting Stone of the Bath-Doulting district, and 

 to the Clypeus-Gx'ii of such sections as that of the Bath-Road 

 Quarry, Nailsworth ; and its massive nature is certainly remin- 

 iscent of the Doulting Stone of the typical locality. In the 

 lower portion of the Clypetis-Gx'ii, Nerincea Guisci, Witchell, is 

 not uncommon. It will be recollected that this gastropod 

 characterises this subdivision as far south as Radstock, and — 

 so far as is known at present — as far north as Rodborough 

 Hill, near Stroud.

 Rev. Steinhauer, and were figured by Sowerby, came no doubt from the Upper Trigonia-Gnl of a 

 quarrv " situated at the verv top of the road which runs straight up the hill." 3 Quart. Joum.
