give way to more massive lighter coloured chalk, and the top of 
the Lower Chalk is reached a little to the north of the tumuli, 
but there is no clear section, and the Belemnite Marls were not 
seen. 
Mr. Hill found the upper part of the Lower Chalk exposed in 
the quarry, half a mile south-west of Bury, but in the face now 
being worked a slip seems to have occurred, the beds being dis¬ 
torted and broken. The Belemnite Marl is exposed in the south¬ 
east corner. 
Mr. Reid saw the lower part of the Chalk Marl in the railway 
cutting between Amberley and Amberley Station, and he describes 
it as consisting of “ sandy marl and hard bluish marl containing 
Imall grains of glauconite and some flakes of mica.” He also 
remarks that “ between Sullington Hill and Bury a grey sandy or 
siliceous chalk appears about 140 feet below the Melbourn Rock, 
and almost immediately below the Grey Chalk. This material 
seems to replace part of the Chalk Marl and not to belong to the 
Greensand.” 
The following note is by Mr. HillMr. Pepper’s quarry, about 
a quarter of a mile north of Amberley Station, is about 80 feet 
deep ; 60 feet of this is in massive smooth white chalk, passing 
down into greyer chalk, the lowest 10 or 12 feet being in courses 
divided by marly bands. In the floor of the quarry a narrow work¬ 
ing disclosed about 20 feet more of grey chalk and grey marl in 
alternating courses. No fossils were seen, nor did the quarrymen 
possess any. 
The following is a list of such fossils as have yet been obtained 
from definite zonal horizons in western Sussex. Those from Elstead 
were obtained by Mr. Rhodes, those from Duncton by Mr. Bry- 
done.
