calcareous sandstone. At one point, however, near Warshill Top 

 Farm, a thickness of 7| feet of conglomerate is exposed, which is 

 certainly a portion of this bed : in this section the matrix is less 

 calcareous than it is in the other districts. Some fragments in the 

 conglomerate-zone are 6 inches long, and fairly angular. This 

 calcareous band is succeeded by 25 feet of marls. 



Next follows the Upper Permian (D^), which is represented by 

 a trappoid breccia, containing angular fragments, one of which is 

 18 inches long, and many at least 6 inches. 



Between Warshill and the Enville district, along the line of the 

 Bewdley-to-Enville fault, there are two outlying masses of trappoid 

 breccia (D^) underlain by marls, but passing upward in one section 

 into breccia-sandstone similar to that at Gilbert's Cross, Enville 

 (p. 105). Some of the rock-fragments in this breccia are 9 inches 

 long, and many measure 4 inches. The best section is at Castle 

 Hill, where the breccia is faulted against Coal Measures to the west, 

 and is overlain by Lower Bunter sandstones on the east. 



(2) The South Staffordshire Region (PI. XII.) 



This region includes those disconnected Permian districts which 

 fringe the southern half of the South StaiFordshire Coalfield on the 

 south, west, and east. The chief of these is the well-known Clent 

 Hills district. 



2«. The Clent Hills District. 



Here the Middle Permian covers a tract of country 6 miles long, 

 much broken by faults. The Middle Permian strata themselves 

 occupy the low ground at the southern margin of the coalfield. 

 This low ground is followed to the south by the range of the Clent 

 Hills, where the trappoid breccia is grandly developed.
