- VOL. XIV. (2) RHETIC ROCKS 149 
Rheetic at Coomb Hill is 18 feet 11 inches, of the Lower 
Rhetic, 14 feet 4 inches; but probably the thickness 
assigned to the Upper Rhetic is too great. 
From Coomb Hill the outcrop of the Rheetic series runs 
almost due north, the junction with the Upper Keuper 
Marls being marked by a low, but very distinct, escarp- 
ment, and near Tewkesbury their superficial extent is 
considerably extended. No useful exposure is to be 
found in this escarpment. In the neighbourhood of 
Southwick sections are wanting. According to the 
Geological Survey map this area is bounded on the east 
by a fault running approximately north and south, the 
Lower Lias being brought into juxtaposition with the 
Rheetic strata and Keuper Marls. Another fault of, appar- 
ently, less throw runs at right angles to the last, south of 
“The Folly.” In a deeply-cut wheel-track, a little west-by- 
south of “ The Folly,” the Red (Keuper) Marls are exposed 
with grey and yellow marls above. Black shales, capped 
by the Bone-bed equivalent, containing Acrodus minimus, 
succeed. Above are black shales, and these are in turn 
succeeded by a hard sandstone band, the probable equiva- 
lent of bed 13a at Wainlode. The greenish-yellow, marly 
shales of the Upper Rheetic are also visible; and some 
fragments of rock identical in lithic structure with the 
Pseudomonotts-bed were also procured. In the sandstone 
band mentioned above was found a new species of 
Fleterastrea. The record of Heterastrea is especially 
noteworthy, corals being exceedingly rare in the English 
Rheetics—especially in the lower division. 
5-—THE BUSHLEY AREA 
A small portion only of this area is in the county of 
Gloucester, but, for convenience, the description of the 
whole is given in this communication. The chief section 
is situated in a cutting on the Tewkesbury and Ledbury
