hood of Stroud,”* and ‘‘ appears to have its limit southwards at 
Rodborough Hill.”* Above the Upper Coral-Bed he noticed certain 
brown sandy limestones that were not very fossiliferous, succeeded by 
more rubbly beds, teeming at certain horizons with Zerebratula globata, 
capped by certain white limestones, to which he gave the name of 
** White Oolite.” 
Mr Richardson pointed out a thick layer of oysters on top of the 
Upper Zvigonia-Grit, and remarked that borings and such layers 
of oysters usually indicated a break in the succession of deposits, or a 
** non-sequence,” as it is technically termed. Here the ‘‘Grit” and 
Upper Coral-Bed are in apposition. Mr Upton’s work on the micro- 
fauna has corroborated the correlation (founded on other data) of this 
Coral-Bed with that of Midford, near Bath, and with the ‘‘ Coralline- 
Beds” of Dundry Hill, near Bristol. Between the equivalent of 
the Upper Zrigonia-Grit and the ‘‘ Coralline-Beds” at Dundry is the 
Dundry Freestone—a deposit near Dundry Church, about 20 feet 
thick. But there is no representative of it at Rodborough Hill: there 
is a non-sequence. 
In the Bath-Doulting district, above the Upper Coral-Bed, is the 
Doulting Stone, to which succeed the Avabacia-Limestones, and these 
latter are followed by the Rubbly-Beds. Doulting Stone, Anabacta- 
Limestones, and Rubbly-Beds may be collectively spoken of as the 
Doulting Beds. The Doulting Beds are equivalent to the CZyfews-Grit 
of the Cheltenham district. ‘The gradual passage of the more massive 
Doulting Stone into the local Clygews-Grit of Rodborough Hill can be 
admirably studied in the South Cotteswolds. The Anadacia-Limestones 
pass laterally into the White Oolite of Witchell, and in the rubbly 
condition of the top-portion of that Oolite near Stroud—at Scar Hill, 
near Nailsworth, for example—it is possible to recognise the repre- 
sentative of the Rubbly-Beds of the Bath-Doulting district. 
Under Mr S. J. Coley’s guidance, some botanical work was done. 
The following list of plants, which thrive on such spurs of the 
Cotteswold Hills as Rodborough, which are capped with Inferior Oolite, 
has been prepared by Mr Coley :—
