J. W. KIEKBY ON MARINE FOSSILS IN THE 



of white, siliceous, false-bedded sandstone. This band of calcareous 

 sandstone contains numbers of specimens of an Orihoceras (10 inches 

 in length), along with others of Nautilus^ Bdlerophon, Macrocheilus, 

 and other marine forms, mixed with the roots and rootlets of Stig- 

 vyiaria. In the limestone, and particularly on its weathered surface- 

 planes, are strewed multitudes of various species of MurcJiisonia, 

 Macrocheilus, Loxonema^ Trochus^ and other univalves, as well as of 

 species of Lamellibranchs, along with occasional remains of Lepido- 

 dendron and much comminuted vegetable matter. The following is 

 a list of the species : — 



Modiola divisa, M' Coy. 

 Nucula lineata, Phill. 

 Sanguinolites abdensis, Eth. 

 Schizoclus Salteri, Eth. 



axiniformis, Fhill. 



Beyrichia subarcuata,, Jones. 



Kirkbya plicata, Jones ^ KirJchy. 



Leperditia Okeni, Munst. 



Archseocidaris, small spine. 



Spirorbis, sp. 



Cladochonus, ap. 



Tooth and scales of a small Ganoid 



fish. 

 Poecilodus obliquus, Ag. 

 Lepidodendron, sp. 

 Stigmarian roots and rootlets. 

 Plant-remains, obscure. 



Nautilus, sp. 



Orthoceras cylindraceam, Flem. 

 Bellerophon costatus, Sow. 

 Euomphalus neglectus, M'Coy. 

 Lacuna antiqua, M'Coy. 

 Loxonema scalaroidea, Fhill. 

 Macrocheilus fusiformis, Sow. 



acutus, Sow. 



imbricatus, Sow. 



striatulus, sp. noT. 



Murchisonia quadricarinata, M^Coy, 



angulata, Phill. 



striatula, Be Kon. 



Naticopsis elliptica, Vhill. 

 Trochus serrilimba, Fhill. 



sp. 



Cypricardia bicosta, sp. nov. 

 Lithodomus dactyloides, ilf ' Coy. 



Twelve of the above species have not occurred elsewhere in the 

 Lower Carboniferous strata of Pile ; and I do not know of a 

 deposit in the same series where Gasteropods are such characteristic 

 fossils. 



Near to high-water mark the limestone runs out, or, rather, passes 

 into a grey shale with sandstone bands without fossils. Towards 

 low-water mark it continues, but its marine shells disappear, and 

 the only fossils found in it are Entomostraca {Leperditia Olceni, 

 var. attenuata, and Kirlchya) and traces of Ganoid fishes and plants. 



Other marine beds appear at various points of the coast ; but they 

 are nearly all recurrences of those already described, containing 

 the same species of fossils, and they never present so continued a 

 sequence as in either of the foregoing sections. 



Perhaps the only other' bed that need be noticed (and it may or 

 may not be marine) is a thin calcareous sandstone, at Kilrenny 

 Mill, east of Cellardyke, which is full of a bi-valve shell, referred to 

 Anthracosia by Mr. Salter. Along with the Anthracosia are found 

 Littorina scotohurdigalensis, Lepidodendron sp., with the twigs 

 attached in some cases, and as drifted stems covered with Spirorbis 

 in others. 



The same bed (apparently) again comes up at Kilminning, east of 

 Crail, with the Anthracosia in still greater profusion. Spirorbis is 

 here attached to the shells, both on the inside and outside of the 

 valves. Leperditia Oheni, var. ecctuberata, also occurs.
