MIDDLE LIAS: DEDDINGTON. 225 
At the old ironstone- works at King's Sutton, situated south- 
west of the rail way -station, the section as recorded by Mr. 
Beesley was as follows : 
FT. IN. 
Soil, very sandy and ferruginous - 2 6 
("Marlstone, with beds yielding Rhynchonella 
tetrahedra, Waldheimia rempinata, and 
A/f'/lrll T' J Terebratula punctata - -42 
IS< \ Marlstone with phosphatic concretions - 10 
I Rusty ferruginoiis concretions - 18 
(_Sandy blue marl and grey shale. 
The Brickyard at the Wharf, Twyford Lane, west of Twyford 
Bridge, N.W. of King's Sutton, showed the following section of 
the lower beds of the Middle Lias : 
FT. IN. 
("Micaceous grey and blue sandy loams - 56 
Hard blue micaceous and sandy limestone 
or calcareous sandstone (like the Starfish- 
bed of Seatown, Dorset), with irony 
Middle Lias<( nodules and in places septaria ; Belemnites, 
Pecten, Pleuromya costata, Modiola 2 to 3 
Blue micaceous clays with small ironstone- 
and cement-stone nodules ; Ammonites 
[_ margaritatus ... about 10 
Mr. Beesley informed me that the Lower Lias with Ammonites 
capricornus, &c. had been formerly reached in the excavations 
here.* The fossils enumerated by him indicate beds like those 
from the Chipping Norton tunnel (see p. 158) at the junction of 
Middle and Lower Lias. A. Hcnleyi (prob. striatus] has also 
been recorded. 
Similar beds of Middle Lias have been exposed at the brick- 
kiln south of Deddington, where the section was as follows : 
FT. IN. 
f Brown and pale- grey ferruginous and mica- 
ceous sands and sandy clays ; with indurated 
calcareous, brown and grey shelly sand- 
,,.,,, , . j stone in places ; one layer at the base - 10 0- 
; ias<; gj ue san dy micaceous clay, passing down 
[ into blue micaceous and slightly cal- 
1 careous clay, with cement -stones * and 
(_ septarian limestones - - about 20 
Large and small Belemnites, B. cylindricus, B. elongatus, and 
B. vulgarisy Ammonites margaritatus, Cypricardia, Ostrea, 
Gryphcea, Pecten aquivahis, Plicatula spinosa, some of them 
pyritic, occur in these beds. Ditrupa circinata is recorded from 
the calcareous sandstone at Twyford and Deddington, and from 
a similar bed at Chipping Norton, by Mr. E. A. Walford. 
The sands and sandstones below the Rock-bed, were to be seen 
on the Banbury road, a little west of Middleton Cheney. f
