276 Cosmo Johns : Lower Carboniferous Rocks of Mill Gill. 



REsuM]fe AND Conclusions. 



The occurrence of a Lower Pendleside fauna in the Yoredale 

 Rocks of North-West Yorkshire is indicated, and the equiva- 

 lence of the Yoredale and Pendleside Series is suggested. 

 The coral fauna of the Main or Upper Scar Limestone enables its 

 correlation with the Great Limestone of North Northumberland 

 to be established. 



The fauna of the Upper Scar Limestone is advanced on that 

 of D2 of the Bristol area, and thus it indicates a higher level 

 than the top of the Visean of the South- West Province of Dr. 

 Arthur Vaughan. 



The identity of the Main Limestone of Ingleborough with 

 the Whittington Limestone near Kirkby Lonsdale, and with the 

 Pendleside Limestone of Longridge Fell and Pendlej^Hill is 

 asserted. 



A tentative classification of the Yoredale Series is put forward.
