FOST-TERTIARY FOSSILIFEROUS DEPOSITS. 75 



28. Dryleys, near Montrose. 



In the brickworks of Dryleys, near Montrose, a thick mass of clay is exposed which 

 reaches the height of 50 to 100 feet. 



In the lower part of the mass especially fossils occur, and the presence of Leda 

 arctica, Pecten Grcenlandictis, a large form of Saxicava rugosa, var. arctica, sufficiently 

 marks the character of the deposit. 



Height above the sea forty feet. 



The following Ostracoda were found : 



Cythere glohulifera, Brady. 



— concinna, Jones. 



— mirahilis, Brady. 



— Bunelmensis (Norman). 

 Cytheridea punctillata, Brady. 



— Sorbyana^ Jones. 

 Cytherura concentrica, n. sp. 

 Cytheropteron latissimum (Norman). 



— arcuatum, n. sp. 



— inflatum, n. sp. 



— Montrosiense, n. sp. 

 Sderochilus contortus (Norman). 



29. Barrie, Forfarshire. 



This clay bed is of the same general character as that of Dryleys. It hes along the 

 estuary of the Tay, in a gully in the most recent of the raised sea-margins, which runs all 

 along the east coast, nearly a mile inland. 



The shells indicate a decidedly arctic character ; and amongst them are Mya trimcata, 

 Nucula tenuis, Leda pernula, and Leda minuta. Iloploaster gracilis is not uncommon.
