INFERIOR OOLITE SERIES : NORTHERN COTTESWOLDS. 137 
from 25 to 30 feet by Prof. Hull. Sections also are exposed in 
the lane- and road-cuttings at Coscomb Grove, south-east of 
Stanway, where we find yellow sands with concretions of 
calcareous sandstone and very shelly limestone. These beds are 
overlaid by ferruginous sandy beds (probably belonging to the Pea 
Grit Series), and these again are surmounted by the Lower Free- 
stones. The bottom beds of the Freestone were shown in a quarry 
north of Coscomb Farm, where there were exposed about 12 feet 
of yellowish oolite with ochreous infillings, and fissile shelly oolite 
yielding a few fossils Myacitcs, Rhynchonella, and Terebratula 
maxillata. 
The mass of the Freestone, near Stanway, was exposed at the 
Jackdaw quarry (worked for Lord Elcho), where the section 
showed the following beds : 
FT. IN. 
Well-bedded oolite, much jointed and false-bedded in 
places - - - . - - -250 
White oolite - - - - - 3 
Brown oolite (best freestone) - - - 6 
Yellow oolite - - - - - - 10 
We have no evidence of the Oolite Marl, although its presence 
is noted by Prof. Hull in the hills east of Winchcomb. He gives 
the following section of the quarry east of Stanway Hill Barn* : 
FT. IN. 
'Thin-bedded, brown calcareous sand- 
stone, alternating with marly beds, 
with Modiola sowerlyana, Ostrea 
flabelloides, and Trigonia (casts) - 7 6 
Yellow calcareous sandstone - 2 
Variegated sandy Bhales - - 4 6 
Light brown sandstone - - - 1 
Variegated sandy shales and clay - 8 
Yellow, brown, and black shale, with a 
bed of small oysters - 2 
Upper Freestone- Hard limestone with blue centre - 3 
The mass of these beds evidently belongs to the horizon of the 
Lower Trigonia Grit and Gryphite Grit of Cleeve, but they 
appear to a certain extent to replace portions of the Upper 
Freestone. The beds in this quarry were not well exposed at the 
time of my visit, but I obtained from the upper beds of impure 
limestone, Belemnites, Myacitcs,Gryphcea sublobata, Pinna cuneata, 
and Serpulce ; while beds of iron-shot oolite were intercalated 
with the clays and sandy rocks beneath. The beds were much 
disturbed and bent into a synclinal, and those exposed were 
somewhat different in detail from the strata recorded by Prof. 
Hull. 
About 12 feet of the Lower Freestone has been opened up on 
Stanley Hill to the west of Winchcomb ; the underlying beds of 
Inferior Oolite appear to be much reduced in thickness, the Pea
