In this area the Fish Bed was noticed many years ago by 
the Rev. P. B. Brodie, who gives details of the section at 
Bugbrook.J From that locality a fine specimen of Lcpidotus 
elvensis was obtained by Miss Baker, and eventually placed in the 
British Museum. 
The Upper Lias clay has been exposed in the railway-cutting 
west of Brackley railway-station, and in an adjoining brickyard. 
It consists of blue and grey clay with race, selenite, and small 
cement-stones. Another brickyard north-east of the town,
