168 PROCEEDINGS COTTESWOLD CLUB 1908 
in the zone of Ammonztes Parkinsonz, Sow.; at Walditch 
Hill, near Bridport, where it is associated with Col/yrites 
vengens and Flolecty pus hemisphericus.* At Charlecombe, 
as already stated (footnote, page 166), there is no Inferior- 
Oolite deposit of earlier date than the Upper 77zgonza- 
Grit, and the greater mass of the Inferior Oolite there is 
made up of Doulting Beds. Since the equivalent of the 
Upper Z7zgonza-Grit at Charlecombe was recognised in 
Wright’s time, if the specimen had been definitely re- 
corded therefrom, he would probably have said so, and 
therefore the likelihood is that it came from the Doulting 
Beds. 
The only specimen which we have obtained from the 
Cotteswolds, came from one of the very local marly beds 
at the base of the equivalent to the Azadacza-Limestones, 
or White Oolite, exposed in a temporary excavation in 
connection with the construction of a reservoir (tank) on 
the summit of Stinchcombe Hill. From this it would 
appear that the horizon occupied by this echinoid in the 
Cotteswold Hills is approximately the same as in Dorset. 
According to Mr Buckman, the deposits in which it 
occurs so abundantly in Dorset are probably of inter- 
Truellet-zigzag date, and this agrees with the horizons of 
the Cotteswold records, and that of a typical form from 
the Doulting Stone of Doulting (Phyllis Collection, 
Shepton-Mallet Museum).
