HIND : CARBONIFEROUS ROCKS OF THE PENNINE SYSTEM. 425 
pecten papyraceus, Gbjphioceras reticulatum, G. spirale, G. bilingue, 
and other species, none of which occur below. Only ca few brachiopoda 
oi the Carboniferous Limestone pass up into these beds, but the 
peculiar fauna enumerated above recurs at various horizons in the 
Millstone Grit series and lower coal measures. The limestones 
become thinner and thinner, and towards the top of the series sand- 
stones and quartzose gannisters appear in the shales, and become 
more and more pronounced until the Grits come on. So much for 
the general sequence in Derbyshire. 
The sections from Pendle Hill to Clitheroe show a sequence 
perfectly parallel to that which obtains in Derbyshire. The shelly 
detrital beds and crinoidal limestones being specially well marked. 
Very fine and almost complete sections are to be seen in the Angram 
and Pendleton Brooks, and the doughs on the west flank of Pendle 
Hill. These beds yield a typical fauna, as may be noted by an ex- 
amination of Appendix B (page 401). 
The sections in the Massif of limestone near Clitheroe show 
a white massive limestone full of shell fragments or made up of crinoids 
at the top, while lower down, as at Chatburn, a series of dark blue 
limestones with their shale partings are in evidence. Further west 
inliers of the Limestone Massif, consisting of the upper and f ossiHferous 
beds, protrude through the Pendleside shales at Withgill, Ash not, 
Doe Barn, Whitewell, Chipping. Sykes, and Slaidburn, at which places 
good specimens of the typical fossils of this horizon can be obtained. 
The beds at Sykes were largely altered by vein stuff, but contain 
Amplexus camlloides and Lithostroiion sp. The Pendleside series 
are to be seen in the brook courses and a few quarries round these 
inliers at Black Hall and Cold Coates, S.W., and Thornley Hall, south 
of Chipping ; the river Hodder ; quarries below the Longridge Fell 
escarpment ; below Ashnot Barn ; Holden near Bolton-by-Bolland ; 
streams at West Bradford and Grindleton ; the river Kibble near 
Dinckley Hall ; and the typical fauna of the series has been obtained 
at all these localities. 
A most interesting set of beds occur at or about the top of the 
Limestone Massif, along a line extending from Thornton to Barnolds- 
wick. This is an anticlinal hill, a N.E. and S.W. axis, the limestone
