is only on the first of these that the Rhetic and Liassic 
strata have been differentiated. When the Rhetic deposits 
come to be mapped, without doubt they will be found 
to occupy a very considerable superficial extent. Since 
the dip of the beds is usually very slight, the writer 
has traversed the greater portion of the area occupied by 
the Lower Lias as shown on the Geological Survey Maps, 
on the possibility of finding the higher beds of the Upper 
Rhetic Stage somewhere exposed. For convenience of 
descriptive purposes the districts where these rocks occur 
may be described as an eastern and a western. 
The noticeable northward trend of the two districts 
occupied by the Rheetic_and Lower Lias (excepting the 
south-eastern portion of the eastern district in the neigh- 
bourhood of Cleeve Prior and North Littleton) is due to 
their preservation in synclinal flexures. Physiographically, 
this flexuring has produced some interesting phenomena— 
especially as regards the streams. In several places 
“through valleys” traverse the western escarpment of the 
western area: even where that escarpment is most marked, 
as near Crowle. The eastern limit of the same district, 
except for an extent of about two miles near Feckenham, 
is faulted ; consequently, rivers flow across the line of 
junction of the Keuper and Liassic Series without giving 
rise to any phenomena which call for attention. 
The main anticline, upon which the above-mentioned 
synclinal flexures are dependent, has a Malvernian trend, 
that is, north and south; and in the area under considera- — 
tion, runs from a little east of Feckenham, southwards 
towards Cropthorne—the Charlton Abbots Valley being on 
the same line of elevation. The completeness of this 
anticlinal flexure, between a mile east of Feckenham, and 
three-quarters of a mile east-south-east of Netherton, is 
interrupted by a fault: the Lower-Lias strata having 
been brought into juxtaposition with the Upper Keuper
