208 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jan. 12, 
Before concluding the description of the beds of the Upper Series, 
it may be well to call attention to a singular arrangement of drift 
which occurs in a brick-pit on Black Hill, Snitterfield, near War- 
wick (fig. 3). 
A somewhat wedge-shaped mass of compact “ clunchy” clay of 
red and greenish colours was observed on the face of the pit to 
break the continuity of a bed of light-red loam, and to rest, as far 
as one was able to judge, upon the laminated clay below. Its di- 
mensions, as measured on the face of the section, were 66 feet from 
A to B, 30 feet from C to D, vertical depth 19 feet. The total size 
of the mass is not known, nor was I able to trace its superficial area. 
It appeared to contain sand mixed up with clay and quartzose 
pebbles. The locality is on the most elevated ground thereabouts. 
I could not detect any dislocation of the beds of red loam along the 
lines A to Cand B to D. I may mention here that a fragment of bone, 
now in the possession of Mr. Kirshaw, F.G.S., of Warwick, was 
said by the foreman to have been found in the gravel-bed below.

G. Starting from the discovery of a bed of unstratified quartzose 
flinty drift at Bredon, near Tewkesbury, which was described by 
Strickland under the head of “‘ Marine Erratic Gravel with Flints ” 
(Trans. Geol. Soc. N.S. vi. p. 554), I have succeeded in tracing the 
existence of beds of a similar character in various localities, from 
Berry’s Coppice, near Donnington, to within a short distance of 
Tewkesbury. As will be seen from the general Table of Localities, 
they occupy elevations from 180 feet to 67 feet above the river 
Avon. As a general rule, decreasing in altitude seaward, on the 
south-east side of the Avon, between Evesham and Bredon, they 
range along the upper edge of an escarpment of Lias which les at 
the base of what I have termed the main valley; at the bottom of
