in the Bunter-conglomerate beds in the neighbourhood of Broms- 
grove, present in many cases the same appearances; and some of 
them are found with cracks across them, which yield to the pressure 
of the hand. 
C (8) has only been observed hitherto at Snitterfield, Welcombe 
Hill, and in a brickfield near the New Inn, Ridgway, accompanying 
the beds B (2) and F. It varies from about 7 feet to 4 feet in 
thickness. 
D (4). This bed appears to be the one which is most persistent in 
its occurrence of any in the upper series. It has been traced from 
the neighbourhood of Rugby, where it attains to a minimum thick- 
ness of about 50 feet near Hillmorton, to near Princethorpe, where 
it occurs both under the Boulder-clay and between it. It is met 
with again in the neighbourhood of Warwick and Leamington, con- 
tinuing down as far as the Lenches, beyond which there is no certain 
evidence of its occurrence, although it probably underlies the red 
loam on Cracombe and Charlton hills. The exact thickness of the 
bed has not yet been ascertained where it occurs in the neighbour- 
hood of Rugby; but in the district of the New Red marl it averages 
about 10 feet in thickness. In some of the localities it contains 
quartzose pebbles and flints. 
E (5). This deposit bears much resemblance to the freshwater 
gravel hereafter to be described. It appears to be a well-washed 
bed of gravel and sand, containing pebbles of white quartz, a few 
flints, and numerous water-worn specimens of Giryphwa incurva and 
Belemnites. I also obtained from it a fragment of coral and what 
appeared to be a fragment of Encrinite limestone. It is doubtful 
whether it exhibits any signs of stratification or not. The only loca- 
lities in which I have met with it are at Snitterfield, near Warwick, 
near the Brickyard, Leamington, and Welcombe Hill, near Stratford- 
on-Ayon. It is said to occur near the ‘“‘ New Inn” on the Ridgway. 
In order to make clearer the order of superposition of the deposits 
above described, I subjoin two typical sections—the one taken from 
the beds occurring in the Lias district, and the other from the area 
of the New Red marls.
