the limestones at this spot, for there is no indication here of 

 passage-beds. 



The junction of the limestone and the shales above is not quite 

 clear. In the bed of the Hamps, immediately beyond the bridge 

 and below the schoolhouse, is exposed a thick massive limestone 

 dipping 40° south-westward. The overlying beds are obscured, but 

 a few yards farther up the stream a continuous section in black 

 shales, with occasional thin calcareous beds and strings of calcareous 

 concretions, is seen for some little distance. So far as we have been 

 able to search them, they yield only Posidoniella Jcevis, Glyphioceras 

 hilingue, and fish-remains. The beds seem to belong to the upper 

 portion of the Pendleside Group : the Pendleside Limestones have 

 probably been cut out by a fault 



About 1| miles west of Waterhouses the Leek road crosses the 

 Hamps, in which are exposed a series of fine grits and shales, 

 probably representing the base of the Millstone-Grit Series. It is 

 to be hoped that the excavations for the new railway, soon to be 

 built along this valle\% will settle the succession definitely. 



The Marsden and Saddleworth District. 



Between Castleton and Clitheroe the Carboniferous Limestone is 

 not exposed, and the intervening country consists chiefly of Mill- 

 stone Grits and Coal- Measures. Two valleys, however, the tribu- 

 taries and upper streams of the Mersey and the Calder, have cut 

 down to the shale-and-limestone group (the Pendleside) below the 

 grits, and show good sections of the Pendleside Group. 



Messrs. J. Barnes & W. F. Holroyd ^ have given a good description 

 of the beds as they occur at Mossley, Saddleworth, Diggle, and 

 Marsden, and have been able to record very complete collections of 

 fossils from this horizon. The fossiliferous beds consist of shales, 

 with courses of dark hard limestone and bullions, and they have 

 demonstrated that certain beds must have contained the Coal- 

 Measure genera Carhonicola and Naiadites. We have had the oppor- 

 tunity of repeatedly examining the collections made by those two 

 gentlemen, and are convinced that these genera do not occur in 

 the same beds as the other fossils, because the matrix is not the 

 same. Unfortunately neither of these genera has been found in situ, 

 for the specimens were collected from the waste-heaps from the 

 tunnel beneath Pule Hill. The characteristic fauna of the bullions 

 and limestones comprises
