Eastwards from Hough’s Coppice and close to the fence 
which divides the uncultivated land of the hill from the fields . 
below (at B on the map), there are two or three exposures of 
a second limestone not so nodular in character as that before 
mentioned, showing the same approximate dip (45° east), and 
characterised by an abundance of Atrypa reticularis ; Orthis 
canaliculata ; and Bhynchonella Wilsoni; with 0. elegantula, 
Euomphalus sp., and other forms. 
On the survey map a fault is shown running along the 
general line of this fence, and these rocks are in such a 
position that they would appear to be abruptly truncated at 
an acute angle along that line. 
A little north of this (at D and C on the map) some very 
ill-defined exposures of sandy rock are met with, containing 
numerous casts of fossils, among which have been identified 
Holopella gregaria; Strophomena rhomboidalis ; and Bhyn¬ 
chonella borealis (?). 
Northward again, in Botvyle Quarry, a magnificent section 
is seen of a similar limestone to that at B, and containing a 
similar abundance of Atrypa reticularis; Bhynchonella 
Wilsoni; and Orthis canaliculata ; as well as B. crebricos- 
tata; B. nucula ; Strophomena filosa ; Clionetes striatella ; 
Murchisonia sp. Here the dip is quite changed, and is at 
about 85° to the south. These beds may be traced in an 
easterly direction towards the line of fault, where they appear 
to end abruptly. 
Near Botvyle Farms are two other exposures of shaly 
material (F and G on the map), where the determination of 
the dip has not been satisfactorily made out; both contain 
calcareous nodules and are fossiliferous, but I have not vet 
explored them sufficiently to give a list of the organic 
remains. At G (which is close to a pond) the rocks appear 
to be horizontal, and the purple and green colours are very 
suggestive of some shales that are to be seen at Minton and 
Plowden (Tarrannon ?). 
Minor exposures of the upper limestone and of the shales 
of L occur at F, 0, and Q on the map.* 
* Since writing the above, a further exposure of Lower Ludlow 
shale has been observed in Caradoc Coppice, near Q, containing an 
abundance of Phacops caudatus and other forms, a full list of which 
is to appear in the Caradoc Record of Bare Facts for 1892. This is 
probably the same as that mentioned by Murchison, op. cit., p. 232.
