The followiDg paper is an attempt to define the geographical extent, 

 stratigraphical sequence, and palseontological horizon of the beds 

 which lie between the top of the Mountain Limestone and the 

 series of grits known as the Millstone Grits. V^e have taken as the 

 type-section that on Pendle Hill (Lancashire), where these beds 

 attain their maximum development ; and as the term Pendleside 

 Limestone has alread}' been employed by the officers of the 

 Geological Survey to designate the calcareous member of the group, 

 we propose to extend the term to the whole group defined above 

 and call it the Pendleside Group. 



It will be observed that this term includes the ' shales-with- 

 limestones' that rest on the Mountain Limestone of the Derbyshire 

 and jS'orth StaSordshire area, to which the name ' Yoredale ' has 

 been frequently applied ; but one of us has already demonstrated the 

 fact that the Yoredale Series of Wensleydale is totally diff'erent from 

 the Pendleside Group, and that the former is the equivalent of the 

 upper part of the Carboniferous Limestone massif, both on palaeonto- 

 logical and stratigraphical grounds.^ 



The present paper is divided into six sections : the first being a 

 brief introduction ; the second describing in some detail the various 

 occurrences of the beds with their fossils ; the third embodies a 

 general account of the palaeontology ; the fourth is a sketch of the 

 probable physical conditions of the period ; the fifth describes some 

 of the chemical and physical characters of the rocks ; while the 

 sixth deals with the petrology and micropalseontology. In the 

 Appendices are tabulated the fossils of the Carboniferous Limestone 

 Series and the Pendleside Group.
