﻿Yol. 64.] THE rOSSILIFEROUS SILUEIAN ROCKS OF TOETWOETH. 523 



from Cinderford Bridge as far south as Palfield they are shown as 

 resting on the Llandovery ; while, from near Falfield to Whitfield, 

 they are represented as overlapped on the west by the Trias. 

 They are represented as including two very regular bands of lime- 

 stone, one immediately below the Ludlow and a second at about 

 the middle of the Wenlock Series. ISo Weolock Beds are shown 

 on the eastern side of the horseshoe margin of the Bristol Coalfield, 

 or between the Old Eed and the Llandovery west of Tortworth 

 Church. 



In William Sanders's map the limestone is not represented as 

 forming two regular bands, but as a good deal broken up. 



Our mapping is in disagreement with that of the Geological 

 Survey in the following respects : — 



(1) We find an area of Wenlock rocks in the south-eastern part of the 



region in the neighbourhood of Charfield Green, where the Survey- 

 map shows only Llandovery beds.^ 



(2) We find an area of Wenlock, and probably Ludlow, intervening 



between the Old Eed and the Llandovery south of Daniel's Wood. 



(3) We find the Wenlock of Falfield separated from the Trias of Eastwood 



by a narrow band of Llandovery. 



(4) Although a few fossils which suggest Ludlow affinities have been met 



with at various spots, we have obtained no clear evidence of the 

 presence of rocks of this horizon, except in the region to the south 

 of Daniel's Wood, and even here the normal Ludlow fauna of 

 Herefordshire and Shropshire is not met with. 



(5) In the Geological-Survey map a large area of Llandovery is shown 



between Lower Stone and Falfield. The exposures here are very 

 scanty, but such as we have been able to obtain indicate that this area 

 is occupied by W^enlock rocks. 



(6) In the Geological-Survey map the Wenlock Limestone is shown forming 



two very regular bands. While the lower limestone-band runs with 

 regularity, we do not find this to be the case with the upper. Thus, 

 while at the southern end of the outcrop at Whitfield there are 

 clearly two regular bands as shown in the Survey-map, farther north 

 near Gambril Lane there are no present indications of limestone- 

 bands ; while yet farther north, in the area west and south-west of 

 Daniel's Wood, there are three parallel bands, although perhaps this 

 may be due to faulting or folding. 



For purposes of description, the Wenlock Beds may be divided 

 into those of 



(A) The Western Area, including the districts of Horseshoe Farm, 



Whitfield and Falfield, Daniel's Wood and Tortworth, Stone and 

 Woodford; and 



(B) The Eastern or Charfield-Green Area. 



(A) The Western Area. 



This is by far the larger and more important of the two, and 

 extends from the neighbourhood of Horseshoe Farm, near Milbury 

 Heath on the south, to the neighbourhood of Middlemill on the 

 north, a distance of rather over 3 miles (fig. 1, p. 513). 



Throughout the area exposures are very bad, and no quarrying
