Crinoid ; another specimen has been figured as a plant | Aroides 
Stutterdii,) but Dr. Woopwarp has pronounced it to be the 
proboscis of a Orinoid, and will so describe it. 
In a well sunk on Stroud Hill in connection with the Water 
Works the lower part of the Stonesfield Slate was found to be 
laminated, and split up on exposure like the true roofing tile. 
I estimate this part at 5 feet thick, but it may be more. 
There is little variation in the lithological character of the 
Stonesfield Slate between Stroud Hill and Stancombe Ash, but 
eastwards from the latter place it becomes more sandy and 
fissile, and is worked for roofing tiles. The upper bed of the 
Section consists of thin bedded Great Oolite, about four feet 
thick, distinguishable from the underlying beds in being lighter 
in colour, softer in structure, and more fossiliferous. The 
Great Oolite appears to thin out as it extends westward, and it 
is probable that its limit was not far beyond the present 
escarpment of the Cotteswold range.
