J: E. Marr — The Coniston Limestone Series. 99 



The other groups are well displayed in the tract of country 

 between Shap Wells and Millom, and I propose to consider this 

 "tract first, commencing at the east end. 



The most easterly section has been lately described (Harker and 

 Marr, Q.J.GS. vol. xlvii. p. 272). I would point out here that the 

 limestone referred to the Stile End beds in that description may 

 possibly be a member of the Roman Fell Group. 



A considerable mass of fossiliferous ashy beds underlies the 

 conglomerate near the Spa Well, and this mass may possibly repre- 

 sent the Stile End beds (the Yarlside rhyolite being here absent). 

 The limestone above the waterfall at the head of the plantation 

 presents lithologically a closer resemblance to the limestones of the 

 Eoman Fell Group than to the less pure limestones of the Stile End 

 Group ; but as no fossils have hitherto been recorded therein, the 

 point must remain doubtful. 



The lower limestone of the Wasdale Head section (Q.J.G.S. vol. 

 xlvii. p. 271) is however, without doubt, the representative of that 

 •of Stile End, and lies immediately below the Yarlside rhyolite. 



The section in Stockdale Beck is also given in our paper upon the 

 Shap granite (p. 270). I would add a few words to the description 

 given in that paper. 



The Stile End Series is, as represented in our section, faulted 

 against the rock of the underlying volcanic group. The evidence 

 for this fault we hope to present in a future paper. 



Above the nodular upper surface of the Yarlside rhyolite a thin 

 band of ash is developed in Stockdale Beck. 



The main mass of the conglomerate above this consists of 

 subangular fragments chiefly of rhyolite, embedded in a slightly 

 ■calcareous ashy matrix. The highest part of the conglomerate 

 (well seen in Browgill) differs from this. It contains only a few 

 "pebbles which are mostly well-rounded, embedded in a tolerably 

 fine calcareous matrix, and it passes up into the limestone of the 

 Applethwaite Series, and is only separated from this series in the 

 present communication on account of its importance as an easily 

 recognizable horizon. The Ashgill Group is faulted out in Stock- 

 dale, but is seen in Browgill below the zone of Diplograptus 

 acuminatus. 



Few fossils have been obtained from the beds of this section ; 

 though fossils are abundant, they are indifferently preserved. 



Crossing the valley of Long Sleddale, we find the Coniston Lime- 

 stone Series well seen on the hills between that valley and Kentmere, 

 especially near the farm of Stile End. 



The Stile End beds are here quarried, and consist of grey-green 

 •calcareous ashes, weathering yellow, and containing abundant fossils, 

 though these are badly preserved. We have identified : — 



Lindstrcemia stibduplicata, M'Coy. 

 Phaeops, cf. Eichwaldi, Schmidt. 

 Orthis vespertilio, Sow. 

 caMigramma, Dalen.
