Specimens of the strata and fossils were forwarded to the 
Museum at Jermyn Street, by Mr. Hamilton, and also by Messrs. 
Le Grand and Sutcliff, to whom I am indebted for the above 
record. The fossils were named by Messrs. Sharman and Newton. 
In addition to the species mentioned, some others were sent 
without records of depths : they include Area Stricklandi, Cypri- 
cardia intermedia, and Pecten Thiollieri, probably from the base 
of the Middle Lias. A. specimen of Ammonites planorbis was 
stated to come from a depth of 850 feet. The actual junction of 
Lower and Middle Lias cannot be determined within about 20 
feet, and the record now given differs from that published in several 
newspapers by Messrs. Le Grand and Sutcliff', as a number of 
fossils have since been examined, which enable the junction to be 
determined within nearer limits, and to reduce the former estimate 
of the thickness of the Lower Lias. 
The total thickness of the Lias in this neighbourhood may be 
reckoned at 1,360 feet, as the Upper Lias clay has been estimated 
at 120 feet by Mr. Hamilton. Nowhere else in this country has 
so great a thickness of the strata been ascertained, for even in York- 
shire the measured sections of the Lias show a full thickness of 
under 1,100 feet. 
At Cherrington, in shelly limestone belonging to the zone of 
Ammonites capricornus, numbers of the large Coral, Montlivattta 
Victories, were found by Messrs. Tomes and Slatter. One other 
locality is known where they occurred in equal profusion, and 
that is the water-works at Grimsbury, Banbury, where Mr. Beesley 
informed me they were even more abundant than at Cherrington. 
A large collection of fossils was obtained by the Rev. S. Lucas, 
from the cutting on the Banbury and Cheltenham Railway at 
Mangersbury, near Oddington. The zone of Ammonites Henleyi and 
other beds were exposed, but the horizons of the fossils recorded 
are not indicated.* A. well sunk at Bliss's Factory, Chipping 
Norton, proved 500 feet of Lias, chiefly clay belonging to the 
Lower Lias and lower part of the Middle Lias. The sinking was 
abandoned, as no water was obtained.f
