92 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 

 soUtary specimen of Cytlieridea 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 :
