The conglomerate c is plentifully charged with fragments of the 

 Black and other Lower Cambrian Limestones, and it is now proved 

 for the first time that the Black Limestone must be grouped with the 

 Lower Cambrian. 



The surface of the solid Black Limestone is coated withaphosphatic(?) 

 skin, and a similar deposit in the Comley Quarry has within the last 

 two or three years yielded recognizable fragments of Paradoxides sp. 

 and Borypyge Lalcei, Cobbold. The black skin must, therefore, be 

 regarded as the lowest deposit of the Middle Cambrian age that is 

 known in the district. 



Among the numerous fossil fragments that occur in the Lower 

 Cambrian Limestones of this excavation the following have been 

 identified : Anomocare (?) puHtulatum, Cobbold, Callavia Callavei, 

 Lapworth(?), Microdiscus Attleboretisis, S. & F., sp., Protolenus sp., 

 Kutorgina sp., Linnarssonia (?) sp. 



Excavation No. 55 exhibits a faulted junction between the Middle 

 and Lower Cambrian, the hard, ringing Grit (beds d above) being 

 brought into contact with the Green, Micaceous Sandstone (beds a 

 above). 



Excavation No. 56 proved the existence of both the Qiiartzite and 

 the lower part of the Lower Comley Sandstone at another point in 

 the area. 



A section constructed embodying the results of these excavations 

 provides evidence that the Lower Comley Sandstone has a thickness 

 of about 480 feet. 



3. ESTHERIA IN THE BuNTER OF SoUTH StAFFOEBSHIRE.' By 



T. C. Cantrill, B.Sc, F.G.S. 



RECORDS of fossils in the British Bunter are few in number, and 

 some are open to doubt in respect either of their organic 

 character or of the stratigraphical position of the beds that yielded 

 them. Omitting those cases where the horizon formerly supposed 

 to be Bunter has been corrected later and is now accepted as settled, 

 the following appears to be a complete list, in chronological order of 

 their discovery : — 



1. Dictyopyge catoptera (Ag.), a small fish, from Rhone Hill, 

 3 miles south-east of Dungannon, co. Tyrone. Upper Bunter (f^). 

 With this was associated Estheria portlocki. 



2. * Annelid tracks ' at Hilbre Point, Wirral, Cheshire. Lower 

 part of the Bunter Pebble Bed (f-). 



3. Plant-remains, referred to Schizoneiira paradoxa, Schimper and 

 Mougeot, at Sneinton Vale, near Nottingham. Uppermost bed of the 

 Bunter Pebble Bed (f^). 



To these three older records can now be added the following new 

 discovery^ : — 



4. Estheria cf. minuta (Alberti), from Ogley Hay, near "Walsall, 

 South Staffordshire. Bunter Pebble Bed (f^).
