The series of shales with limestones which dip off the dome on aU 

 sides are not so well developed as on Pendle Hill, and the shale 

 separating them from the main limestone-mass has also considerably 

 thinned out. The stream west and north of Ashnot Barn shows 

 thin limestones, shales with calcareous ' bullions,' and cherty beds, 

 containing the Pendleside fauna (Glyphioceras reticidatum, Cho- 

 netes Laguessiana, Athyris amhigua, and Posidoniella Icevis). 



Between the Withgill inlier (which is of the white, massive 

 Clitheroe type with similar fossils) and the grits of Stonyhurst all 

 the intermediate beds occur. The beds are much disturbed along 

 this line, but in the Hodder, near Hodder Place, is a good 

 section showing dark crystalline limestone with much chert and 

 alternating with shales. An excellent diagram of these beds, 

 i^educed from a drawing by Mr. Wm. van Waterschoot van der 

 Gracht, is given by Dr. Henry AVoodward in a paper on new 

 Carboniferous trilobites.^ The following fossils were named by 

 Mr. E. B. Newton, P.G.S., from these beds : — 



Fragments of vertebrata:— possibly phalangeal bones of a small reptile (?) 



and part of the jaw of a small fish (?), 

 Cephalopoda. Discites {Nautili(s) sulcatus. 



Ortkoceras IcBve (?). 



0. cylindricum (f) . 



0. pyramidale (?). 

 Lamellibvanchiata. EntoUum (Pecten), sp. nov. 

 Braehiopoda. Athyris lamcUoaa (?J. 



Chonetes (i) sp. 



Vroductus sp. 

 Polyzoa ? Falceocoryne. Very doubtful. 

 Trilobita. PhUlipsia Van der Grachtii. 



Ph. Pollen i. 

 Echinodermata. JNumerous ossicles of arms of crinoids. 

 The coral Lonsdaleia is stated to occur in one of the bands of limestone. 



Prom the position of this section, midway between the Carboni- 

 ferous Limestone of Withgill and the grits of Stonyhurst, its true 

 horizon can be definitely stated (although we know that the 

 beds are interrupted by local disturbances) to be at or about the 

 horizon of the Pendleside Limestone, probably somewhat below it. 

 The species of the various fossils are stated by Mr. P. B. JSTewton 

 as doubtful, but we do know that the Pendleside Group in verj- 

 many localities contains Discites, two species of Orthoceras, Athyris 

 ambigua, Chonetes Laguessiana, and one or two species of Productus. 



It is interesting to note that PhUlipsia Van der Grachtii occurs 

 in the greyish shales which come on some 200 or 300 feet above the 

 limestone of Ashnot. My specimens have been kindly identified 

 for me by Dr. Henry Woodward, P.R.S. Here they occur in a 

 greyish calcareous shale. This trilobite is also found in the shales 

 at Whitewell mentioned immediately below, aiid at Newton Gill
