POST-TERTIARY ENTOMOSTRACA. 



The fauna of the Cardium edule bed was similar to the fauna of any locaUty on the 

 west coast in which that species abounds. In a very small quantity of material the 

 following Ostracoda were found : 



Cy there pellucida, Baird. 

 Cytheridea papillosa, Bosquet. 

 Loxoconcha impressa (Baird). 

 Xestoleberis aurantia (Baird). 

 Cyiherura yibba (Milller). 



5. Isle of Cumbrae. 



The village of Millport, which stretches along the shore, is built on the old twenty- 

 five-feet sea-beach. From the pier to the west end of Karnes Bay, under a thin crust of 

 soil, is a bed of Melohesia, more or less thick, which, for the most part, rests on the 

 sandstone rock of the district. It is curious to notice that, although at this stretch of 

 the beach the Melohesia is lying in beds of considerable thickness, none of it is found 

 in the sea in the bay opposite to it ; but at the south-west end it is most abundant, both 

 m the raised beach and in the sea. 



The fauna is entirely recent. The shelly material is much water-worn, and loses 

 little in washing, Mollusca are more abundant than either Eoraminifera or Ostracoda. 



The following Ostracoda were found : 



Pontocypris mytiloides (Norman). 



— trigonella, G. 0. Sars. 



— acupu7ictata, Brady. 

 Cythere pellucida, Baird. 



— mridis, Milller. 



— lutea, Miiller. 



— alhomaculata, Baird. 



— convexa, Baird. 



— pulchella, Brady. 



— villosa (G, 0. Sars). 



— angulata (G. 0. Sars). 

 Cytheridea papillosa, Bosquet.
