Bigelow (1915, p. 298) obtained it in the July-August cruise (1913) of the 

 Grampus only in the outermost stations, apparently from 10 to 20 miles outside the 

 continental shelf, and in the more northern of the outer stations not at all, as these 

 were apparently not far enough out for it. "We may perhaps deduce from these facts 

 that this species comes nearer to the coast as the summer progresses, that its 

 distance off the coast increases as we go northward from Chesapeake bay to the 

 Grand Banks, and that along our shores it belongs to the Gulf Stream water coming up 

 from the south, and not to the cold boreal (water coming down from the north. The 

 occurrence of this species in the far north (74° N". according to Michael, 1913, p. 26) 

 and in the far south (77° S., Fowler, 1907, p. 3) would lead one to expect it in our
