(1) The Lower Ludlow Shales. 



The lowest beds exposed in the district are seen along the 

 north side of the Teme Valley west of the hamlet of Weston. 

 The} r are indurated mudstones. and greatly resemble the Wenlock 

 and Lower Ludlow Shales of Builth. 2 A diligent search has 

 revealed no graptolites, but the occurrence of numerous small 

 lamellibranchs and species of Orthoceras distinct from those in 

 higher beds seems to indicate a Lower Ludlow horizon. In the old 

 quarry about half -a -mile west of Weston these beds dip steeply 

 at 24° north-north-westwards, while in the rail way -cutting less 

 than 100 yards away to the east they are apparently horizontal, 

 and, judging from the inclination of the succeeding beds, the high 

 dip displa} r ed in the quarry-section is due to purely local folding. 



(2) The Aymestry Group. 



The Aymestry Limestone is absent from this district. 



The indurated mudstones just mentioned pass up gradually into 

 a great thickness of shales, which, towards the base, tend to be 

 dark-grey and massive, with an irregular fracture and no very 

 marked budding. Such rocks are seen in the lower part of the road 

 from Chapel Lawn to Pentre Hodrey and again at Obley. In the
