CALCIPEEOUS SAIfDSTONE OF FIFE 



563 



east of Pittenweem Harbour, where it has yielded me the following 

 fossils : — 



Fossils of Zone 5, at 2280 feet (the Encrinite-bed of Mr. Brown's 



paper). 



Nautilus quadratus, Flem. 

 Orthoceras attenuatum, Flem. 

 Bellerophon deoussatus, Flem. 



Urii, Flem. 



Dentalium priacum, Goldfuss. 

 Loxonema sealaroidea, PhilL, and 



variety, 

 Maerocheilus acutus. Sow. 



fusiformis, Sow. 



Murchisouia striatula, De Kon. 



sp. 



Naticopsis, sp. 

 Pleurotomaria Yvanii, Lev. 

 Aviculopecten arenosus, Phill. 



granosus, Phill. 



fimbriatus, Phill. 



Cypricardia, sp. 

 Leda attenuata, Flem. 

 Leptodomus oostellatus, M' Coy. 

 Nucula gibbosa, Flem. 

 Schizodus unioniformis, Phill. 



carbonarius ?, Portl. 



Venus ?, sp. 



Athyris ambigua, Sow. 



Discina nitida, Phill. 



Productus semireticulatus, var. Mar- 

 tini, Sow. 



Spiriferina eristata, Schlotheim.. 



Streptorhynohus crenistria, Phill. 



Bairdia plebeia, Beuss. 



Hisingeri, Miinst. 



brevis, J. Sf K. 



subelongata, J. ^ K. 



Beyrichia subarcuata, Jones. 



radiata, J. ^ K. 



Oythere, sp. 



Archgeocidaris Urii, Flem. 



Actinocrinus, Poteriocrinus, Platy- 

 crinus (fragmentary remains of the 

 calyx and stem of species belonging 

 to these three genera). 



Spirorbis helicteres, Salter. 



Stenopora tumida, Phill. 



Plants— large and small fragments of 

 stems, belonging to Lepidodendron 

 and Badoxylon. 



The Crinoidal remains are very abundant about and in the lime- 

 stones. The most characteristic fossils among the MoUusca are the 

 species of Leda., Nucida, Discina, Productus, and Spiriferina, some of 

 which more especially mark certain horizons of the bed. 



Most of the speciovS are found in the shale close to the coal, as 

 well as higher up, though some of them are there rather dwarfed, 

 the Univalves and Crinoids more particularly. One of the most 

 common fossils in this position is the Productus, which occurs with 

 its long and slender spines attached to the shell, within an inch or 

 so of the coal. 



A little to the east of the Eock and Spindle, near St. Andrews, 

 there is a shale with a band of crinoidal limestone, which I 

 take to be the same bed as this. In it are found the following 

 species : — Orthoceras attenuatum, Bellerophon Urii, B. decussatus, 

 Dentalium scoticum, Euomphalus acutus, Murchisouia striatula, 

 Aviculopecten granosus, A. sp., Edmondia rudis, Leda attenuata, 

 Schizodus axiniformis, Lingula mytiloides, Productus semireticu- 

 latus, var. Martini, Spiriferina eristata, Bhynchonella pleurodon, 

 Fenestella tuber culocarinata, Stenopora tumida, and a few small 

 Ganoid scales. The crinoidal remains are smaller than at Pitten- 

 weem, but apparently belong to the same genera. 



About 40 feet below the Encrinite-bed is a four-inch band of very 

 hard limestone, full of the shells of Myalina modioli formis. This 

 is the highest horizon at which I have observed this gregarious shell, 

 so characteristic of the lower portion of the Calciferous Sandstones,
