stream, down which the usual strike-fault runs, and the lowest 

 beds seen on the right bank are mudstones, of which a thickness 

 of 1 foot 6 inches occurs. Above this are 5 feet 8 inches of 

 Graptolitic shales, having the ordinary lithological characters of the 

 convolutus-zone, and containing its fossils. A pale-green band, two 

 inches thick, occurs a foot above the base of these shales, and 

 at first sight it appeared as though the shales, with many specimens 

 of D. tamariscus, would occur beneath this ; but this was found not 

 to be the case, and we believe that the mudstones at the bottom of 

 the section belong to the convolutiis-zone, and that the shales with 

 many specimens of D. tamariscus should occur beneath this, and are 

 not here exposed. Fossils : — 



Monograptus convolutus, His, 



leptotheca, Lapw. 



gregarius, Lapw. 



— — Nicoli, Harkn. 

 Eastrites ureeolus, Bichter. 



Eastrites hybridus, Lapw. 

 Diplograptus tamariscus, Nich. 

 Climacograptus normalis, Lapu 

 Aptychopsis. 



kb 6. The Barren Band here consists of two feet ten inches of 

 blue mudstones, passing down into the beds below. (It will be 

 convenient if we remark that a passage is understood unless otherwise 

 intimated.) It yielded LeptcBna quinquecostata, M'Coy, and Whit- 

 fieldia tumida, Dalm. ? 



Ac 1. The Clingani-hsiJid is represented by one foot of grey-blue 

 Graptolitic shale, with the usual fossils accompanying the cha- 

 racteristic small 3£. Clingani, and above it is Ac 2, the Amjyyx- 

 aloniensis zone, of which only two feet are seen, and which yielded 

 no fossils. 



The Browgill Beds occur in isolated outcrops on the moorland, at 

 several places between Long Sleddale and Kentmere, but they 

 present little of interest. 



Kentmere Sections. 



No section of any importance occurs on the east side of the Kent- 

 mere valley, the hill-sides being largely occupied with turbary. A 

 number of dip-faults run down the valley, shifting the beds to some 

 extent, and the first good section of the Stockdale Shales is seen in 

 the bed of the Kent, just east of the church. Only the upper 

 portion of the Browgill Beds occurs here, with the usual fine, 

 hard, greenish-grey grit interstratified with shales ; but the passage 

 into the Goniston Plags is admirably displayed, the Browgill Beds 

 having interstratified bands of blue mudstones towards the summit, 

 until at last these preponderate, and the pale bands become 

 rarer, and finally disappear altogether, the complete passage taking 

 place in the course of twenty or thirty feet. 



On the west side of the valley the dip-faults become very 

 numerous, and the beds are greatly shifted laterally, as shown by 

 the outcrop of the Coniston Limestone ; but we meet with no 

 exposures of the Stockdale Shales until arriving at a point some 

 distance above the bottom of the Kentmere valley. Here two small
