^Ol* 57'] PENDLESIDE GROUP AT PENDLE HILL, ETC. 367 



number of limestones between the grits and the ' massif ' or Great 

 Scar Limestone — for this is the term applied to the variable quantity 

 of undivided limestone — is not constant, but increases, almost in- 

 definitely, as the beds pass northward. 



At Ingleboro' the fifth bed of limestone below the Grit is called 

 the Hardraw Scar ; but in Wensleydale the fifth bed, reckoning 

 downward, is called the Simondstone, and the sixth is called the 

 Hardraw Scar. On reckoning from below, while at Ingleboro' the 

 Hardraw Scar Limestone is the first limestone above the main mass, 

 near Hawes another bed, the Gayle Limestone, is found in the 

 shales separating them. 



Up to the present, the fauna of the shales and limestones of the 

 southern type has not been found north of the Craven Faults, 

 although it seemed to us probable that some remnants might occur 

 in the shales and upper limestones connected with the Crowstones, 

 which come on below the grits in the valleys of the Eden and 

 the Swale. Careful and repeated examination has failed to show 

 the Pendleside fauna at this horizon. On the contrary, these beds 

 contain a fauna identical with that found in the shales of the Car- 

 boniferous Limestone Series of Scotland. 



The Felltop Limestone of ISTorthumberland, too, seems to have 

 a, Carboniferous-Limestone fauna, and, according to Prof. Lebour, 

 contains Productus giganteus.^ 



A complete and important section of the beds between the Mill- 

 stone Grit of Nine Standards Pell, south-east of Kirkby Stephen, as 

 shown in Faraday Gill, has been published by one of us,^ but no 

 fossils of the Pendleside type were obtained there. A suggestive 

 bed of limestone associated with chert occurred in a sandstone 

 series some little distance below the base of the grits. 



A good section in the same beds was obtained in Far Cote Gill, 

 on the eastern flank of Swarth Fell, nearly opposite Hell Gill : — 



Mnistone Grit Series.

 attemiata, Protoschizodus axiniformis (large), and Plfurotomaria sp. 



Shales. 



Thick limestone, probably the Main Limestone. 



Black shales with Productus sernireticulatus.
