POST-TERTIARY ENTOMOSTRACA. 



7. Oban. 



A bed composed of earthy matter, shell debris, and small gravel, was reached in 

 digging the foundation of a house on the east of Oban, and also in a railway-cutting in 

 the same vicinity. The material is more muddy and has less of a washed appearance 

 than is usual in raised beaches. 



It occurs on a small plateau at the mouth of a rivulet which might have supplied 

 the sediment. Only one example of fluviatile Ostracoda, however, was found, — a 

 solitary specimen of Cytheridea lacustris. The deposit has altogether the appearance of 

 a recent sea-bottom, which has been uplifted to its present position, rather than of a 

 beach. The fauna is that of the surrounding waters. 



Height above the sea ten to fifteen feet. 



The following Ostracoda were found : 



Paraci/pris polita, G. 0. Sars. 

 Pontocypris mytiloides (Norman). 



— trigonella, G. 0. Sars. 

 Bairdia inflata (Norman).

— viridis, Miiller. 



— pellucida, Baird. 



— castanea, G. 0. Sars. 



— crispata, Brady. 



— alho-maculata, Bairil. 



— convexa, Baird. 



— pulcheUa, Brady. 



— villosa (G. O. Sars). 



— angulata (G. 0. Sars). 



— setnipunctata, Brady. 



— Jeffreysii, Brady. 



— cuneiformis, Brady. 



— laticarina, Brady. 



— emaciata, Brady. 



— antiquaia (Baird). 

 Cytheridea torosa (Jones).
