THE LOWER OOLITES HEAR BRISTOL 
and from the Dispansi hemera to the Opaliniformis hemera ^ 
at the latter place. 
Jay Hill, near Bitton. 
A section in the Midford sands can be seen at Jay Hill 
east of Bitton Station. Some hard beds at the base 
contain badly preserved Ammonites of Upper Lias (sic) 
character and a number of small undetermined Brachi- 
opods ; the softer beds appear to be unfossiliferous, as 
is usual. 
Upton Cheney and North Stoke, 
A little further east, at Upton Cheney and at North 
Stoke, a Cephalopoda bed can be traced in the road cuttings, 
and from it many Ammonites have been obtained, in- 
cluding Grammoceras dispansum and Dumortieria Moorei ; 
the distinctive Brachiopod Rhynchonella cynocephala is 
also common. 
Directly above the Cephalopoda bed at these localities 
tliere are a few feet of Inferior Oolite limestones contain- 
ing fossils characteristic of the Parkinsoni zone, thus in- 
dicating a break in the deposits from, at least, Opalini- 
formis to Garantianae time. A similar non-sequence is 
very general in this district, excepting at Dundry, where 
some of the missing beds are represented.

At the base of the Inferior Oolite limestone series at 
Dundry there is a series of clays and sandstones — the
