G. 0. Sars has caught this species at Skroven (Lofoten). 

 According to Sars^) the species is mentioned from Finmark by Mr. 

 Andrew, but is has, however, not been taken there later. 



Friele and Grieg^) give the distribution of this species to 

 the depths between The Hebrides end The Faroe Isles, Portugal, 

 The Azores and Senegambia. On our coast the species is limited 



1) (s) means that only empty shells were fniind.

I to the great fiord depths with tlieir particularly constant temperature 

 ! and .salinity (0 — 7" C, about 35 7oo). 



As The Vest Fiord is the most northern of the principal fiords 

 where these physical conditions prevail. I am inclined to think that 

 the mention of this species from Finmark must be a mistake. 



The northern limit should be looked upon as Lofoten, until 

 there is definite information that it is di.stributed still further nortli- 

 wards.

G. 0. Sars has found shells df this species at Skroven. My 

 catches in Moskenstrommen prove that the species still exists at 

 Lofoten, which must therefoi'c be considered to be its northern limit 

 on our coast.
