Vol. 52.] ASSOCIATED BEDS, IN N. DEVON AND W. SOMERSET. 261 



At Morte Point, in addition to some large Lingulce, the slates were 

 found to be covered with minute individuals of the same genus, but, 

 as their structure was completely obliterated, very little could be made 

 out of them. In the section (fig. 1) I have marked the positions of the 

 fossil zones, and the folds in the rocks which are to be seen between 

 Morthoe and Woolacombe. The same beds have doubtless been 

 several times repeated, but in some of the broken folds it is 

 probable that there are strata which belong to very different horizons. 

 Moreover, there is a somewhat marked difference in some of the 

 deposits. The flaggy beds which alone enable us to make out the 

 folds are succeeded by fine-grained dark slates, and as these are 

 found at a height of about 500 feet in the hill above Barricane, it 

 is clear that they alone must attain to a thickness of several 

 hundred feet. 



III. Eockham Bay, Bull Point, Lee Bay, Lee, and Slade. 



Near the centre of Kockham Bay there is a well-marked fold in 

 which are some hard, gritty bands, and on the northern side dark 

 bluish-grey slates, which have yielded some small Lingulce, but no 

 other distinguishable fossils. Between here and Bull Point there 

 are indications of another broken fold, and at Bull Point the dip 

 is N.N.W. in striped grey flaggy beds, which exhibit extensive 

 shiny cleaved surfaces. Similar rocks in well-marked folds are 

 found extending along the coast towards Lee Bay. In flags ob- 

 tained from a quarry on Flagstaff Hill, on the south-western side 

 of Lee Bay, I obtained some very large Lingulce. On the eastern 

 side of the same bay are much crushed slates with fucoid-like 

 markings on the surface, and in the cliffs towards Shag Point are 

 greenish and yellowish flaggy beds, sometimes stained of a pinkish 

 colour. Small Lingulce were fairly abundant in some of these beds. 

 Between Shag Point and Flat Point the beds are much broken, and 

 there are clear indications of an important fault. Beyond the 

 fault towards Ilfracombe the rocks are more massive in character, 

 and as they also contain many sandstone-bands, and have not 

 yielded any fossils, I have, for the present, thought it well not to 

 include them with the Morte Series. They are also separated from 

 the typical Ilfracombe Beds by a fault, which extends along the 

 depression between Langley and the coast. These beds are well 

 exposed in the Slade quarry, dipping S. at a high angle at its western 

 end, and folding round to the N. at its eastern end, where there 

 are beds of reddish and yellowish sandstones. These rocks call to 

 mind some of the Pickwell Down sandstones and shale-beds ; but it 

 must be admitted that at present their age, owing to the absence of 

 fossils, is indeterminable. In the Lee valley I found a few Lingulce 

 and fragments of encrinites at several points in the Morte Series, 

 and in the quarry opposite the hotel small Lingulce are as abundant 

 as at Morte Point.
