VOL. XV. (3) UPTON—UPPER LIAS AT STROUD 207 
corresponding beds at Churchdown there is a very con- 
spicuous band of rock which has been identified as the 
“ Saurian and Fish-Bed” of Moore, but although there are 
in the Stroud section no fewer than six beds of rock 
somewhat similar in appearance, I have failed to find any- 
thing in them which would justify the correlation of any 
one of them with the Churchdown and Ilminster Saurian 
and Fish-Bed. Nevertheless I consider that the series 
should be correlated with that zone. Some of the clay 
beds have a conchoidal fracture. J have washed portions 
of the most promising looking clays, and although they 
contain a considerable number of Foraminifera and Ostra- 
coda, the small interesting Brachiopoda of the Leftena- 
Beds are entirely absent. Foraminifera, though fairly 
abundant in some of the beds of clay, comprise fewer 
species than the LeJtena-Beds. The Nodosarian group, 
which is most abundant in the Leftena-Beds, is almost 
wanting, whereas Cyvzstedlaria, which is comparatively 
infrequent in the Lefiena-Beds, is extremely common in 
the upper beds of clay. Ahynchonella Bouchard, which 
marks a thin clay-bed in the Ilminster district, appears to 
be absent from the Cotteswolds. 
The upper portion of the clay-beds (Saurian Zone) 
has been subjected to denudation and is quite uneven, 
the denuded surface having a general slope towards the 
north, on which side lies the valley through which the 
Slad stream flows. Along the whole of the face of the 
section which was exposed there extended a thin bed of 
coarse sub-angular gravel, nowhere more than 8 inches in 
thickness, composed of fragments of oolite embedded in 
reddish marl, and upon the top of this another clay-bed 
which had obviously been disturbed and may possibly 
have been placed there when the original buildings which 
occupied the site were erected. At any rate it was clearly 
not an original undisturbed deposit.
