Walk No. VII. 
A little distance up a lane, through the coppice 
leading to Bringewood Hill, is a small quarry of Lower 
Ludlow, from whence I obtained a very perfect Lituites 
articulatus , but the rock is in general very barren. 
At the village of Burrington the Wenlock shale is 
very well exposed in many deep cuttings in the different 
roads ; several of the beds are full of the trilobite; 
Calymene tuberculosa. Graptolithus priodon also, 
abounds, and several small shells. Bellerophon dilatatus 
has been found in a quarry to the north of the Churchy 
also one specimen of the very scarce Ampyx parvulus. 
Phacops longicaudatus is also here, but the best place 
for them is in the bed of the river Teme, a short 
distance below Crifton Bridge, where they can be 
found in great abundance, and in very good preser¬ 
vation. 
Close to Downton Castle Bridge, on the right bank 
of the river, the Ludlow bone bed is exposed, con¬ 
taining its usual remains ; Onchus spines are very fine 
here. About three feet higher up the rock, in the 
Platyschisma bed, I obtained several heads of a small 
Cephalaspis or Pteraspis , covered with very small 
tubercles. The walk from here to the Bow Bridge, by 
the side of the river, which rushes through a deep 
narrow gorge formed in the Upper Ludlow rock, is a 
most delightful one, and alike interesting both to the 
geologist and botanist. In the grounds near to this 
walk, more than twelve species of ferns are to be met 
with, including Scolopendrium vulgare , the beautiful 
hanging fronds of which in many places cover the high 
cliffs ; Polypodium vulgare , dryopteris , and phegopteris ; 
Cystopteris fragilis , angustata , and deniata ; Asplenium 
Adiantum-Nigrum ; Polystichum aculeatum , angular?, 
and lobatum , and Blechnum spicant. The section by the
