Eare, but quite typical fossils. As this is a distinctly Boreal 

 species, it may be assumed that the specimens have been washed 

 from the Glacial drift which underlies the Brick-earth and Alluvium 

 of the peninsula. At the present time its distribution is confined to 

 the Arctic seas and the cold areas of the Atlantic Ocean and North 

 Sea, immediately to the southward of the Arctic Circle, such as 

 the cold area of the Faroe Channel.

Eecent, very rare ; but frequent in the fossil state, and from 

 various strata. One specimen at least is silicified and apparently 

 from the Chalk.

One fossil specimen ; typical and in good preservation. This 

 species does not appear to have been hitherto recorded in the fossil 

 state. Brady's specimens are from shallow water from various 

 tropical localities. Under such conditions, the species has a fairly 

 wide distribution. Our specimen is probably from one of the 

 Tertiary strata which were laid down under similar climatic 

 conditions.
