More pnpaeform and apparently with much closer, finer sculp- 

 ture than N. ni.f/ellri. yet they may very possibly be identical. I 

 do not hesitate to place these species in this group, although 

 the}^ posses* an exterior lip-varix. since otherwise, the relation- 

 ship is sufficiently apparent.

Dredged at a depth exceeding 150 fathoms (precise depth not

 fragile. Owing to the depth of water it has the appearance of 

 the Arctic mollusca. The species of NCIMI are decidedly littoral 

 in habit, so that this is an extraordinary exception, and raises 

 the question whether the species is really a
