Long lists of the fossils (including more than 300 species) have been pub- 
lished by Mr. Beesley, who has grouped the beds generally under the zone of 
Ammonites Jamesoni, because he found it impossible to fix the precise horizon 
of the majority of the specimens. He obtained about 2,000 Belemnites, 
among which he has recognized about 63 species. It may be remarked that 
he obtained only one example of Ammonites Jamesoni and that an imperfect 
one. A. Valdani is more abundant, but A. latcecosta, mentioned in his lists, is 
a doubtful identification. 
Among the more abundant fossils not mentioned above, are 
Belemnites Icevis, Avicula ineequivalvis, Gryphcea arcuata, Plica- 
tula spinosa, Pcntacrinus scalaris, and Serpula. 
At the waterworks at Grimsbury, many fossils were obtained by 
Mr. Beesley, especially in a stone-band which appears to be local. 
Here the Coral, Montlivaltia Victories, was found in great num- 
bers, as at Cherrington ; Spiriferina rostrata was numerous, and 
Ammonites latcecosta has also been recorded. 
The Brickyard south of Grimsbury, just north of the railway- 
stations at Banbury, showed about 15 feet of bluish micaceous 
sandy clay, at the base of which there is a layer of shelly lime- 
stone, about 1 foot thick, known as the Banbury Marble, which 
rests on blue shale. This stone was not exposed at the time of 
my visit (1887), as water rises when it is reached and prevents 
deeper working ; it is however described by Prof. A. H. Green, 
and a specimen was kindly procured for the Museum of Practical 
Geology, by Mr. E. A. Walford. The clay yields Ammonites 
striatus, A. Loscombei, Belemnites, Amberleya, Unicardium car- 
dioides, Pleuromya costata, Inoceramus ventricosus, Goniomya
