100 POST-TERTIARY ENTOMOSTRACA. 



§ VI. THE FOLLOWING IRISH AND ENGLISH POST-TERTIARY DEPOSITS 

 HAVE BEEN EXAMINED FOR OSTRACODA. 



I. WOODBURN, CaRRICKFERGUS. 



About a mile and a half north of Carrickfergus a bed of clay has been cut through 

 by the stream both a little above and below Woodburn Bridge. This clay is dark-grey 

 in colour and somewhat stony, and contains a few flint pebbles. It is irregularly overlain 

 by from one to five feet of shingle, which appears to represent the old bed of the 

 ^river. In this clay we noticed Leda pernula, Leda pygmma, with fragments of Balani, 

 &c. ; and an Arctic character may be assigned to the deposit. 



The following Ostracoda were found : 



Cythere pellucida, Baird. 



— pulchella, Brady. 



— concinna, Jones. 



— tuberculata (G. 0. Sars). 



— Dunelmensis (Norman). 

 Cytheridea punctillata, Brady. 

 Cytherura complanata, n. sp. 



— ce/Mo^a (Norman). 

 Cytheropteron nodosum, Brady. 



— arcuatum, n. sp. 



— Montr osiense, n. sp. 

 Bythocythere simplex (Norman). 

 Pseudocythere caudaia, G. 0. Sars. 

 Faradostoma variabile (Baird). 

 Poly cope orbicularis, G. O. Sars.
