will in time prove capable of subdivision into recognisable stratigraphical 

 sub-groups. 



As matters now stand it would appear that the components of the 

 Comley Series, as developed in this little area, may be somewhat as 

 follows : — 



1. The Lower Comley Series, whose lowest beds graduate upwards 

 from the Wrekin Qnartzite below, through an unknown thickness of 

 LovKT Comley Sandstone, into the fossiliff-rous Olpnellun group at the 

 top (some 5 or 6 feet in total thickness, and composed in ascending order 

 of (1) the Olenellus Limestone, the French Grey lAinestone, and the Grey 

 Limestones). The affinities of the Black Limestone have yet to be deter- 

 mined. 



2. The Upper Comley Series. — The lowest group of this consists 

 of the Qimrry Ridge Grits (some 24 feet in thickness), made up of 

 a lower conglomeratic Zone with the Paradoxides fauna and a higher 

 gritty zone with few fossils. These Quarry Ridge Grits are apparently 

 succeeded by a thick band of shales, the Quarry Ridge Shales. Still 

 higher in the succession comes the Hill House Group, made up of the 

 Hill House Flags below, the Hill House Grits in the middle, and the Hill 

 House Shales above. 



While the original object with which these excavations were com- 

 menced — i.e., the fixation of the relative systematic positions of the 

 lithological zones which have already yielded fossils in the Comley Quarry 

 and its immediate neighbourhood — has been attained, nevertheless the 

 stratigraphical succession of the component lithological zones of the Comley 

 Series as a whole is as yet far from being established ; and, bearing in mind 

 the fact that in this Comley area the Cambrian strata of Shropshire are 

 known to be far more fossiliferous than elsewhere, it is most desirable 

 that the work shall be continued. 



Throughout these investigations I have had repeated help and 

 encouragement from Professor Lapworth, which I gratefully acknowledge. 



I am also much indebted to Mr. Philip Lake for help in the 

 determinations of the Trilobites, and to Professor Theodore Groom for a 

 report on the Hyolithidfe, &c.

Robin Hood's Bay. — In the spring of the present year three boulders 

 of Shap granite were exposed in the cliffs near Stoup Beck. Two were 

 large, well-worn blocks, about 2 to 3 feet long ; the third not more than 

 8 inches long. One of the larger still remains in sitM, It lies in undis- 

 turbed boulder clay 20 feet above high-water mark, exactly 100 yards
