House, showing about 800 feet of shales and limestones, we 

 obtain the following succession : — 



pg ^ ^ Feet. 



B .. I Dark bard limestones, with concboidal fracture ; 



i 5 J finely stratified 40 



p « jSbales, with occasional tbin bniestoues 200 



H ^ J Dark hard bmestones, with concboidal fracture ;

Black shales occur beneath these limestones, but unfortunately 

 there is much disturbance and the beds below are repeated and 

 faulted. At any rate, it is impossible for the top of the mass of 

 white limestone to be very far below this point. 



The stream near Mixon Hey, in these beds, yields a rich fauna 

 with Posidonomya Becheri. 



The section exposed by the new Ashbourne & Buxton B,ail- 

 way, reports of which have been published independently by Mr. H. 

 H. Arnold-Bemrose and one of us.^ shows a succession of limestones 

 and shales with volcanic ashes and tuflPs at the top, much contorted 

 and folded. The section is as follows : — 



Feet. Inches. 

 Shales, with eighteen bands of tbin lime- 

 stone yielding Aviculopecfen papy- 

 raceus, Fosidonomya Becheri, & Posidoni- 



ella Icevis in the upper part 2o 



Chert 3 



Calcareous shale 4 



Massive shelly limestone, with Productus 

 giganteus, etc. and fish-teeth ; in places 



a shelly conglomerate 11 



Shales and bands of limestone 57 9 



Hard grey limestone 3 



Shales with limestones 11 



Shale 6

Hard limestone 2 



Shales and limestone 10 7 



. Earthy limestone 1 



Shale and marl 8 



Volcanic series 144 



The foregoing section shows the junction of the two faunas ; and 

 the varying lithological character of the members of the series 

 indicates that they form a well-marked set of passage-beds between 

 the Pendleside Group and the Carboniferous Limestone. 



The sections in the various quarries at Water ho uses show a 

 considerable series of thinly-bedded limestones with chert-bands, 

 large corals, and many fossils, and a well-marked bed of rolled 

 shells and limestone-pebbles at the top. These beds belong to the 

 Prodvctus-f/iganteiis zone (that fossil is plentiful in the top bed) ; 

 and it would seem that no thickness of shale was deposited between
