rubble of oolite. The beds occur below the oolita (freestone) of 
the " Forest Marble pit " (p. 335). Fossils are veiy abundant in 
the soft limestones and marls, and I obtained the following 
species : 
Natica globosa. 
pyramidata.

Anatina siliqua.

Ceromya concentrica. 
Oorbula involuta P 
Cypricardia. 
Isocardia minima. 
Leda lachryma. 
Myacites. 
Opis. 
Ostrea costata. 
Ostrea subrugulosa. 
Pecten annulatus.

Pholadomya deltoidea ? 
Heraulti.

Thracia curtansata. 
Terebratula maxillata. 
Acrosalenia Wiltoni. 
Echinobrissus clunicularia. 
Griesbachi. 
Woodwardi. 
Holectypus. 
' Sowerbyi. 
The assemblage may be compared with that found in bed 15, of the 
rail way- cutting west of Hook Norton (p. 330). 
Many fossils have also been collected by Mr. Beesley, including besides 
many of the species mentioned, Astarte, Gyprina, Modiola, and Crustacean 
remains (Glyphea).* 
These beds occur approximately on the horizon of beds 11 to 16 in the 
section near Hook Norton. 
Beds of Great Oolite have been observed on Constitution Hill, 
to the W.S.W. of Banbury. They comprise alternations of marl 
and limestone with Ostr'ea and Rhynchonella concinna, resting on 
oolite and marl, together little more than 12 or 15 feet thick; 
beneath which come the sandy beds of the Inferior Oolite. 
Sections have been recorded by Mr. Beesley, on whose authority 
the above notes are given, t 
South-west of Dane Hill, south of Deddington, the 
cutting showed the following beds :
