HIND : CARBONIFEROUS ROCKS OF THE PENNINE SYSTEM. 435 
The limestone yields Productus giganteus, and a very large coral, 
Cyathophyllum StutchburyL and Crinoid debris. 
The dip varying from 10° to 20" almost due north. 
About three-quarters of a mile west of the above, five exposures 
are seen in the high banks of the northern tributary of the Swinden 
Beck. Both exposures have been quarried. 
The most northern quarry shows — 
Shale, becoming calcareous at base. () ft. 
Hard compact limestone. 2 ft. 3 in. 
Earthy shale. 9 in. 
Hard limestone, base not seen. 6 ft. 
Talus. 12 ft. 
Dip a little W. of N. 10° to 20°. 
The middle quarry continues the section downwards, and shows 
several feet of hard massive limestone with the large corals, Cyatho- 
phyllum Stutchburyi and Zaphrentis cylindrica. 
The lowest quarry still continues the section downwards, and 
shows a further 18 ft. of well-bedded thick limestones and no shales. 
Unfortunately, a gap in the sequence occurs here, but almost 
a hundred yards south the stream shows a succession of black shales, 
the exact position of which is doubtful, but a series of dark limestones 
of Pendleside type occurs in them just east of the railway in Swinden 
Gill, 
Further north massive limestone is seen between the Craven 
Faults, and is well exposed in the scars of Malham, Settle, and Giggles- 
wick. The upper beds at Malham and Settle yield the usual rich 
fauna of the Carboniferous Limestone. No trace of any interstratified 
shales or sandstones are to be seen. 
The shale series which underlies the Millstone Grit rocks west 
of Malham is shown by its fossils to belong to the Pendleside series 
(Hind and Howe, of supra, cit., pp. 359, 360), and possibly some of 
the shales immediately below the grits of Black Hill may belong to 
this series. But there is a thin limestone which is seen in a stream 
a quarter of a mile west of Black Hill, which contains Productus 
latissimus, and is therefore shown to belong to the Yoredale series. 
At Clattering Sykes, in Outside Grizedale. is a spring which washes
