Oolitic calcareous sandstone and shelly 
oolite ; resting on false-bedded shelly 
and oolitic limestones, with calcareous 
sandy layers, abundant ripple-marks,

sistent clay -beds - - 13

Here the Forest Marlile is reduced to about 16 feet in thickness. 
There is a specimen of Apiocrinus from Kirtlington, in the collection 
of Mr. James Parker, of' Oxford : the occurrence of this fossil is 
interesting, as no other record of it has been noted in the neigh- 
bourhood, not even at Jslip where foasils indicating the horizon of 
the Bradford Clay have been found. 
Towards Tackley, according to Prof. Hull, the Forest Marble 
becomes very thin, while in the direction of Middleton Stoney it 
is represented by clays overlying 5 or 6 feet of shelly oolite, with 
bands of clay.* 
Chipping Norton to EpwelL 
Further to the north-west we find occasional outlying patches 
of Forest Marble. 
In the cutting at Pest House, south-east of Great Rollright, 
on the railway from Chipping Norton to Banbury, the Cornbrash 
and Forest Marble have been exposed, attention being drawn to 
the sections by Mr. T. Beesley, Prof. Morri?, and Mr. Hudleston.t 
The beds which I noted, were as follows :

Cornnbrash - Tough grey limestones (see p. M6) 6 
"Band of hard calcareous sandstone, and 
sandy shale - - . - 1 
Irregular false-bedded series of bluish 
shales, with thin beds of sandy lime- 
stone, and inconstant beds of oolitic 
limestone and calcareous sandstone ; 
with much lignite - - 15 6 
Blue shelly oolitic limestones with 
lignite - -.30 
Yellowish marly clays with harder 
lumps of marl : Ostrea Scwcrbyi, Ger- 
villia, &c. - - - 2 6 
A number of fossils were collected by Mr. Beeeley, including 
Fish-remains, Cyprina loiveana, Ostrea Sowerbyi, Pccten annulatus, 
P. vagans, &c., and I obtained Gervillia crassicosta, Unicardium 
impressum, and U. varicosum ^ 
Another outlier of Forest Marble has been ob c erved on the 
east of Tadmarton near Banbury. (See p. 335 )
