426 HIND : CARBONIFEROUS ROCKS OF THE PENNINE SYSTEM. 
beds forming the limbs of the anticlinal being very tliin and separated 
by shales, which, toward the top, become fairly well developed. This 
portion of the limestone is a southerly continuation of the anticlinal 
of Haw Bank and its continuation to Bolton Abbey, and its secondary 
folds round Draughton. Here, the upper part of the Limestone 
Massif is split up by shale beds, which attain some little thickness. 
Sections at Rain Hall and Gill rock quarries, Barnoldswick, show 
this condition of deposit very clearly. Further south-west a similar 
set of beds are seen in the Lancashire and Yorkshire Railway, one 
mile north of Rimmington Station, and still further S.W. at the 
large quarry two miles south of Chipping. 
I consider the beds along this line to be a local phase of the close 
of the limestone deposit, probably due to a current which brought 
detrital sediment and deposited it in a definite and strictly limited 
area. The fauna of the sliales intercalated with these limestones 
is peculiar and interesting. At Draughton, in a small quarry near 
the railway, tlie shales yielded a fine specie of Ctenacanthus tenui- 
striatus. 
The limestones at Draughton yielded Cardiomorpha ovata, and 
the Rev. A. Crofton tells me he has obtained species of Spirifery 
Product us, PJiillipsia, and Corals here. 
At Thornton Quarries I obtained — 
Cladochonus sp. Very frequent. 
Palcechiniis sphciericiis. Very frequent. 
Crinoid-stems. 
Conocardium Hihernicum. 
The following specimens were found'at Rain Hall Quarries : — 
Cladochonus sp. 
Palcechinus sphcericus. 
Crinoid-stems, three species. 
Productus semireticulatus. 
Orthotetes crenistria. 
Athyris planosulcafa. 
Conocardium aliforme. 
Syringopora geniculata. 
Zaphrentis Enniskilleni.
