found usually in deep water all around those islands 

 (M'Andrew and E. F.). According to Mr. Jeffreys, it 

 occurs at Bantry, in Ireland. On the Northumberland 

 coast it is found in the same situations with Islandicus, 

 but is rare (Alder) ; in sixty fathoms off Northumberland 

 (Howse). It is i^robably essentially a boreal species. In 

 the northern drift it is a common fossil.

The extreme rarity of this beautiful shell renders it 

 probable that certain of the features indicated in our 

 description may prove rather to appertain to the specimen 

 than to the species. Although allied in form to the two 

 preceding shells, the peculiarities of its sculpture and 

 aperture readily distinguish it from either. It is of a 

 fusiform shape, which is rather more attenuated above 

 than below, and is chiefly swollen a little below the 

 middle. It is moderately strong, yet not quite opaque, 

 and is clothed with a somewhat shining shaggy brown epi- 

 dermis, which is not thick and level, but so disposed 

 in longitudinal flakes and reflected, where it passes over 

 the riblets in fringe-like filaments, as partially to reveal 

 the decussated sculpture beneath it. The surface is of 

 an uniform more or less glossy white or piidiish white,
