POST-TERTIARY ENTOMOSTRACA. 



^ VI, THE FOLLOWING IRISH AND ENGLISH POST-TERTIARY DEPOSITS 

 HAVE BEEN EXAMINED EOR 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 pernida, Leda pygmcea, with fragments of Balani, 

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

Cythere pellucida, Baird. 



— pulchella, Brady.
