VOL. XVI. (2) INFERIOR-OOLITE ECHINOIDS 187 
abounds on the high ground around Stow-on-the-Wold. 
It finds its analogues in the CZypeus Agasszzt and C. altus 
of more southern regions, and connects the widely- 
separated and lithologically-distinct deposits. 
The little Acrosalenza spinosa helps to endorse this 
correlation. It occurs abundantly in the Doulting Beds 
at Doulting; has been recorded from the equivalent beds 
in the South Cotteswolds, and has been obtained as far 
north as the “ Seven-Springs Quarry,” near Cheltenham, 
where it was derived from the same horizon. 
Before Clypeus Plotz gives place to Clypeus Agasszzz it 
becomes associated with Collyrites ovalts. Collyrites ovales 
occurs in the Doulting Beds of Doulting, in which a 
young specimen of a Stomechznus, with little doubt S. 
bigranularis, was also found. C7lypeus Agasstze occurs 
in the equivalent beds in Vallis Vale. 
In Dorset, Stomechinus bigranularis is very eemndant 
in beds which Mr Baeewian thinks are most likely of 
inter-77ruellet-zigzag date. 
Hence the conclusion is that the Stomechznus-Beds of 
Dorset are on about the same horizon as the top-portion 
of the Doulting Stone + the Axadacza-Limestones + 
the Rubbly Beds of Doulting ; the CZyfeus-Grit (local) 
+ the White Oolite + the Rubbly Beds of the South 
Cotteswolds: and the CZypeus-Grit of the Mid and North 
Cotteswolds. 
Crossing the Channel into Normandy, we learn from 
M. Munier-Chalmas’ /7éczs of his excellent and obviously 
accurate work,’ that the succession there is as follows:
