792 LÖNNBERG, ON CEPHALOPODS ETC. 



dredged 3 specimens between Norway and Beeren Eiland, and 

 between the latter and Spitzbergen, 1 ) but the most northern 

 locality where that expedition found Rossia glaucopis was 75° 

 53' N, 21° 51' E. With the addition to the knowledge of the 

 geographical distribution of this species which has been made by 

 this summer's Swedish Expedition to Spitzbergen it can be taken 

 for certain that Rossia glaucopis is to be found everywhere 

 round Spitzbergen at suitable localities. 2 ) 



The arctic specimens do not seem to difFer from those collec- 

 ted at the westcoast of Norway as I have had the opportunity 

 to see by making comparison with a specimen dredged in the 

 Trondhjem-Fiord this summer by Arwidsson and Östergren at 

 a depth of 250 m. muddy bottom.

When the Swedish Expedition was engaged in investigations 

 of the »Swedish Depth» between Spitzbergen and Greenland Mr. 

 Kolthoff shot a Cystophora cristata out of which, when it had 

 been hoisted on board, several half digested cephalopods were 

 taken. These were preserved and I have had the opportunity 

 to examine them and have found that such pieces that could be 

 identified belonged to the above mentioned species. This find is 

 of a certain biological importance because it gives us an idea on 

 what the seals are feeding during their pelagic wanderings. It 

 was well known that Cephalopods to a great extent supply the 

 food to pelagic Odontoceti of various species from the sperm- 

 whale to the dolphin and also that pelagic birds like albatrosses 

 prey upon the same kind of animals and now we find the same 

 thing stated about the seals. This tends to show that the 

 cephalopods form an important link in the chain of marine 

 organisms from the microscopical plankton to the mammals.
