Northampton Sand. He adds that in the game great outlier of 
Bredon Hill, we find, above the villages of Conderton and Over- 
bury, a similar series of sections.* The Bambury (Banbury or 
Benbury) Stone is a block of the Inferior Oolite, of a more or 
less rubbly character, 
cemented into a hard 
rock, as in the cases above 
mentioned.t 
The railway-cuttings 
between Andoversford 
and Bourton - on - the- 
Water prepare us for 
some modifications in the 
Inferior Oolite Series 
that may occur further 
north. We have, how- 
ever, ic piece together 
isolated sections, and this 
can only be done ap- 
proximately until the area 
is mapped in detail. 
The Ragstones are well 
shown at Snowshill 
where we find theClypeus 
Grit and Upper Trigonia 
Grit, resting on freestone 
that is exposed to a depth 
of 18 feet. The Trigonia 
Grit is a hard irregular 
ferruginous and earthy 
limestone, about 1 foot 8 
inches thick and of a 
somewhat nodular charac- 
ter. The freestone below 
exhibits a bored surface. 
It contains Pecten per- 
sonatus and Ostrca, and 
appears rather to belong 
to the main Freestone 
division than to the 
horizon noted previously 
as the Notgrove Free- 
stone. In this case there 
is evidence of some over- 
lap of the Ragstones in 
this neighbourhood. 
By the farm, to ; the 
east of Snowshill, we find
