90 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 : 



'O 



Cythere pellucida, Baird. 

 Cytheridea papillosa, Bosquet. 

 Loxoconcha impressa (Baird). 

 Xesfoleberis aurantia (Baird). 

 Cyiherura gibha (M tiller). 



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 Kames Bay, under a thin crust of 

 soil, is a bed of Melobesia, 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 Melobesia 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 

 in 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 Eorarainifera or Ostracoda, 



The following Ostracoda were found 



Pontocypris mytiloides (Norman). 



— trigonella, G. 0. Sars. 



— acupunctata, Brady. 

 Cytkere pellucida, Baird. 



— viridis, Miiller. 



— lutea, Miiller. 



— albomaculata, Baird. 



— convexa, Baird. 



— pulchella, Brady. 



— villosa (G. O. Sars). 



— angulata (G. 0. Sars). 

 Cytheridea papillosa, Bosquet.
