Geographical distribution. — At Arnside and Storth lioad 

 in the Arnside District. At Frith Hall, Park Head, near Cartmel, 

 Longhowe End, and Broad Oak in the Grange District. At- 

 Plumpton, Gascow, Dalton, and Marton in the Furness District. 

 In the Kendal District above Underbarrow, Brigsteer, Beethwaite 

 Green, and at Kettlewell ; also on the banks of the Eiver Kent 

 between Hawes Bridge and Levens Park. Near Lupton Hall in 

 the Kirkby Lonsdale District. In the Docker-Beck section in the 

 Shap District it is merged in the Orton Sandstone, but emerges 

 from below it on Bavenstonedale Moor. Between Blea Flatt and 

 Ashfell Farms, and in Tarn Sike in the llavenstonedale District. 

 In the Westmorland Pennines it appears to be represented b)'- the 

 unfossiliferous sandstone of Swindale Crag which underlies the 

 Melmerby-Sear Limestone. 



((? 7) The Clisioj)liyll%im-mult%sej)tatum Band. 



At the summit of the zone occurs an important band of shale 

 characterized by the abundance of ClisioplnjUurix multisejjtatum, 

 which is immediately overlain by beds containing the earliest 

 examples of LitJiostrotion. Though best developed in the Arnside 

 District, this band occurs in all the Western Districts in the same 

 position immediately below the base of the Gastropod Beds, and 

 also at Turn Sike (llavenstonedale) in the Eastern Districts.
