Localities recorded: Type specimen taken by H. Koch, at: 



1. Vladivostok, eastern Asia, and preserved in the Copenhagen Museum. 

 (Schiodte & Meinert). 



2. " Bought in 1877, of the naturalist-merchant Wessel in Hamburg, ***** 

 habitat: Greenland; a male and female specimen (Zool. State Mus. Sweden 

 at Stockholm and Bovallius collections)". " (Bovallius). The validity of this 

 Greenland locality is questionable, though, as noted by Hansen, it is not impos- 

 sible that a species found at Vladivostok also belongs to fauna of arctic America 

 and may live at West Greenland. Hence the species is listed here, with reserva- 

 tions. Cat. No. 39905, U. S. N. M., 1 specimen taken by the U. S. Bureau of 

 Fisheries steamer A Ibatross, at station 4807, off cape Tsiuka, Japan, in 44 fathoms, 

 July 16, 1906, is the only specimen I have seen.
