 Twenty miles off No Man's Land, in stomach of herring, (S. I. Smith). 

 Off Saint George's Bank, in Gulf Stream, (S. I. Smith and O. Harger). 

 The identity of this species with the Limacina balea Moller, of Green- 

 land, is very questionable. The description of the latter is brief, and 

 no mention is made of the spiral sculpture, which is an important char- 

 acter of 8. Gouldii.

This is the most abundant species on our Atlantic coast, south 01 

 Massachusetts Bay, where it also probably occurs.
