UPPER LIAS: CHELTENHAM, 205 
At Frocester Hill beneath the Midford Sands, Prof. Buckmnn 
noted 20 feet of Upper Lias shales, very micaceous, resting on a 
band of white limestone 1 ft. thick (with Ammonites bifrons, &c.), 
with shales below.* A. serpentinus has also been recorded from 
this neighbourhood, together with traces of the Saurian and Fish 
O * O 
Bed, by Moore. Lycett records Posidonomya Bronni from the 
Upper Lias shale near Nailsworth.f 
East of the railway-station at Brimscombe, there is a brickyard 
which showed ihe higher beds of the Upper Lias clay and the 
passage-beds into the overlying Midford Sands. The section 
showed brown loams and sands, resting on blue micaceous clay 
with a few cement-stones, and iron-pyrites. The total thickness 
of the Upper Lias near Stroud is estimated by Witchell at about 
70 feet. There is also a brickyard at Rock Mill, South of 
Pitchcomb, near Painswick. 
The higher beds of the Upper Lias contain nodules of cement- 
stone, and these according to Prof. HulJ occur " in profusion in 
some of the brooks on the sides of the Cotteswold Hills, especially 
that on the southern base of Crickley Hill." He mentions 
sections of the beds in brickyards at Colesborne, and near 
Andoversford.l 
At Sandwell Park, west of Andoversford a cutting on the 
Great Western Railway showed the following section :

Ammonites * frons, A. annulaius, A. communis, A. I

The fossils were named by Messrs. Sharman and Newton. 
The Upper Lias Clay forms somewhat irregular and lumpy 
ground on the slopes, near Andoversford and Charlton Kings. 
Its thickness at Leckhampton has been estimated at 200 feet. 
The section at Churchdown (called Chosen) Hill has been 
worked out in much detail during the past 30 years, by the Rev. 
F. Smithe. II He has given the following section :
