394 MR. L. RICHARDSON ON THE INFERIOR OOLITE [NOV. I907, 



The Doulting Stone and Anabacia-JAmestones need no particular 

 comment, as they are similar to their equivalents in the railway- 

 cutting; it is the Rubbly Beds that require attention. At one 

 period of my investigation I was inclined to think that these 

 Rubbly Beds were equivalent to the whole of the Clypeus-Qrit of 

 the Cheltenham district. The general resemblance in lithological 

 characters, and the abundant occurrence of the form of Terebratula 

 globata, auctt. so prevalent in the Clypeus-Grit of the Cotteswold 

 Hills at Doulting-Bridge and Farmcombe Quarries, seemed to compel 

 such a conclusion. But later, after I had collected typical examples of 

 Clypeus Agassizi from the Doulting Stone of Vallis Yale, near Frome, 

 and had identified the equivalent deposits in the Stroud district 

 by carefully following the beds from Doulting to Stroud, I found 

 that the Doulting Stone was the equivalent of the ' Clypeus-Qvit ' of 

 the Horton-Rectory Quarry, in the South Cotteswolds, and of the 

 Scar-Hill section, near Nailsworth, and the .^aSac? ^-Limestones 

 of E. Witchell's ' White Oolite ' ; while, in the incipient rubbly 

 condition of the top-portion of the White Oolite in the Wotton- 

 under-Edge and Stroud areas, it was possible to recognize the probable 

 equivalent of the Rubbly Beds. 



The Eullers'-Earth beds, which cap the section, are very fossili- 

 ferous. The species which occur, except the Aulacothyris, are 

 individually numerous, and this renders the non-record of Ornlthella 

 and ffliynelionella Smitlii all the more noticeable. Probably these 

 particular Fullers'-Earth beds are of somewhat earlier date than 

 those in which the Omithella and Rliynchonella usually occur. 



A little less than three-quarters of a mile to the south of the 

 Doulting-Bridge Quarry, by the side of the Evercreech road, is a 

 small quarry in which the following strata are exposed : — 



Quarry by the roadstde, near Farmcombe.

 I. Eubbly Beds. Limestone, pale-brown, rubbly, oolitic ; Tere- 

 bratula ylcbata, auctt., non Sow., Pleuromya

Limestones. base, where Acanthothyris spinosa is not 

 uncommon ; Tecten (Syncyclonema) de- 

 missus, Phillips (nearest to), at 5 feet 



10 inches down 8 6 



III. Doulting Limestone, brownish, less hard, but more 



Stone. massively bedded, top-bed bored by Litho- 



seen 2 



In this section there is no doubt that the top-beds belong to the 

 lower portion of the Rubbly Beds, but the strata upon which they 

 rest differ considerably from the ^wafraaa-Limestones with which 

 their stratigraphical position requires them to be paralleled. The 

 same remark applies to the equivalent beds exposed in the large 

 quarry in the field on the left-hand side of the road a little farther 

 south, which I call the ' Farm combe Quarry ,'
