the limestone seems to disappear, but reappears for a short distance 

 south of the little transverse valley which runs north of "Woodbury 

 Hill Reformatory. South of this point the limestone again dis- 

 appears for a considerable space, and is not seen again until Rodge 

 Farm is reached, where it has a normal dip of 35° (see fig. 20, p. 169). 

 A little north of the farm hard shales are seen, dipping east-north- 

 eastward at 30° to 43° (see fig. 19, p. 168). They appear to be the 

 shales either immediately underlying or overlying the limestone, 

 but the few fossils obtained from them were insufficient to decide 

 this point ; in the absence of the limestone they form^a small 

 escarpment facing west. South of the farm the limestone finally 

 disappears. 



The shales between the two bands of Aymestry Limestone are 

 presumably everywhere of Lower Ludlow age. They are seen only 

 near Easthope Farm and Woodbury Hill Reformatory; in both 

 places they include thin bands of limestone. In the last-named 

 locality the following fossils were collected: — 



Strophomena rkomboidalis, Lind- 



strom. 

 Sir. ftmiculata, M'Coy. 

 Ortiiis lunata, Sow. (?). 

 Rkyiichonclla sp. 



Pentamcrus sp. I Ptilodictya scalpellum, Loasd 



Lingula lata, Sow. (?). I Crinoidea 



Crania implicata, Sow. 

 Phacops caudatus, Briiim. 

 Beyrichia Wilkensiana, Jones (?). 

 Mytilus myttlimeris, Oonr. 

 Favosites fibrosa, Goldf. 



The Upper Ludlow Shales are well exposed at a number of points 

 on the western slopes of Wallsgrove Hill and Rodge Hill, where 

 many of the characteristic fossils may be collected. The direction of 

 dip appears always to agree with that of the limestone near, as may 

 be seen from an inspection of the map (fig. 15 a, p. 164). East of the 

 eastern outcrop of limestone the few exposures of shale have not r 

 so far, yielded characteristic Upper Ludlow fossils. 



The eastern side of the hills under consideration is much more 

 difficult to interpret than the western. 



The Wenlock Limestone, emerging from beneath the Haffield 

 Breccia at the southern end of Woodbury Hill, appears to run con- 

 tinuously, save for a single interruption, as far south as the southern 

 end of Penny Hill. It shows a remarkable disposition, not easy to 

 understand. At Fetterlocks Farm (fig. 18, p. 168), and in the 

 southern part of Dundridge Coppice (fig. 21, p. 169) the limestone 

 forms an anticline. In the former locality this is almost isoclinal ; 

 in the latter the axis dips west. The eastern limb of this anticline 

 shows a series of small undulations with axes passing east and west, 

 as seen in the quarry immediately west of the Coppice. West of 

 Hillside Farm the limestone appears to show fan-structure (fig. 22, 

 p. 169), the beds on the eastern side being apparently inverted. In 

 Penny Hill the beds dip eastward, those on the western side being 

 apparently inverted (fig. 23, p. 169). The great apparent thickness 

 seen here and near Hillside Farm is probably due to repetition by
