100 ME. W. WICKHAM KING ON THE PERMlAir [Feb. 1 899,. 



materials, both angular and rounded, were derived from local 

 ridges now partly buried beneath the Trias. Mr. A. J. Jukes- 

 Browne supports the local derivation,^ and suggests that reason 

 may be found for uniting the Dyas and Trias into one system under 

 some such name as Mercian.^ My conclusions^ that the Clent Hills 

 breccias are locally derived and accumulated, like beds in Persia 

 described by Dr. W. T. Blanford,^ have already been announced. 

 Mr. R. D. Oldham ' thinks that some of the fragments are glacially 

 striated, and acknowledges the proofs of southern derivation ascer- 

 tained by Midland geologists. The foregoing concise summary is 

 not exhaustive.] 



II. DiSTEIBUTION OP THE MiDDLE AND UpPEE PeEMIAN. 



The Permian, in the regions under description, is divisible into 

 three lithological groups : — 



(1) A lower group of marls and sandstones. 



(2) A middle group of calcareous sandstones, locally conglomeratic, inter- 



bedded with marls and sandstones. 



(3) An upper group of marls, with included breccias. 



The only difference between this classification and that of 

 Prof. Hull is that the trappoid breccias are now classed with the 

 Upper Permian instead of the Middle. 



Some of the local outcrops of these Middle Permian calcareous 

 bands are marked on the Geological Survey maps. The whole of 

 the outcrops in South-east Shropshire, as I have worked them out in 

 the field, are shown in the map accompanying this paper (PI. XI), 



These beds occur in two main regions, namely (1) the region of 

 South-east Shropshire between the Piver Severn and the village 

 of Enville ; and (2) the region of South Staffordshire, around the 

 margin of the southern half of that coalfield. 



(1) The South-east Shropshire Eegiou. (PI. XI.) 



1 a. In the Bowhills-Enville district these bands are exposed at 

 Bowhills, ranging to Eidney Hill. The strike is S.S.E. and 

 N.N.W. In places they dip about 5° E.N.E., but are usually 

 flat. A fault bounds these exposures on the E.N.E. Erom 

 1 to 2 miles beyond the fault the same beds again crop out 

 between Compton, near Enville, and Gatacre, near Bridgnorth. 

 The strike is S.S.E. and N.N.W., with dips varying from 3° to 6°. 



1 6. The Warshill district is situated on the south-eastern edge of the 

 Trimpley Old Red Sandstone anticlinal, while the Bowhills-to- 

 Ridney-Hill outcrops occur on its north-western side. At 

 Warshill one band is exposed. The strike is S.W. and N.E., 

 and the dip is south-easterly. The district is bounded by faults.
