410 MK. L. K1CHARDSON ON THE INFEEIOR OOLITE [NOV. I907, 



? Astarte elegans, Acantliothyris spinosa, Rliynclionella hampenensis, 

 a few fragments of ammonites and belemnites, and several fish- 

 teeth (Strophodus). This bed probably rests directly upon the 

 blue Liassic clays. 



The upper portion of the Doulting Stone and the Anabacia- 

 Limestones are seen in a cavern-like opening by the roadside, half- 

 a-mile south-west by west of Wellow Church, and the Upper Coral- 

 Bed was exposed in a temporary quarry between Braysdown Colliery 

 and Woodbarrow Farm. 1 Corals (species of Isastrcea) were very 

 abundant, but rarely well preserved. 



The Upper Coral-Bed and the basal portion of the Doulting Beds, 

 with possibly the underlying Upper Trigonia-Qrit, have been 

 noticed by Mr. H. B. Woodward ' north-west of Bowldish, east 

 of Paulton.'' 2 About 7 furlongs east of Paulton Church, on the 

 north side of the lane, a quarry has been opened along the line 

 of fault indicated on the Geological-Survey map. As might be 

 expected, the beds are much disturbed. Pullers 1 " Earth caps the 

 section, and yielded Acantliothyris midfordensis, A. doulting ensis, 

 * Terebratula globataj Ostrea acuminata, and 0. Knorri. Below 

 are rubbly beds, about 6 feet thick, more clearly bedded towards 

 the base. Prom the upper portion were procured Lima (Limatula) 

 gibbosa, Pholadomya 3furc7iisoni, Strophodus, and Serpula cf. Umax. 

 White oolitic limestones, containing Montlivaltia and Anabacia, 

 and 4 feet thick, separate the rubbly top-beds from the more 

 massive Doulting Stone. 



About a mile and a quarter to the east is the quarry referred to 

 by Mr. H. B. Woodward as opened up ' on Clan Down, south of 

 Camerton Parm.' 3 



(b) Camerton-Farm Quarry, near Radstock.

The next section to be noticed is just over a quarter of a mile 

 away, and is situated at a point where the Bath Eoad joins the 

 ancient Poss Way. 



1 The boundary-line between, the Oolite and the Lias should come much 

 nearer the farm than it is represented to do on the Greological-Survey map,
