The specimen from Moskenstrommen was 15 mm. in height and to the great fiord depths with their particularly constant temperature 



and salinity (6 — 7° C. about -".5 %o). 



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

 where these physica] 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 distributed still further north- 

 wards.

The northern limit for this species is Lofoten.

 G. 0. Saks collected the species in the Varanger Fiord.

This species was previously known right up to The North Cape. 

 Norman in 1890 took it in The Lang Fiord ( South Varanger)-').

('<. ( ). Saks has found shells of this species at Skroven. My 

 catches in Moskeiistrommen prove that the species still exists at 

 Lofoten, which must therefore be considered to he its northern limit 

 on our coast.

The southern limit for the species is Tromso. 



At St. Lyngen II several specimens were taken, the largest 

 measured 22 mm., thus being very nearly as large as the specimens 

 from Spitzbergen which are given as being 24 mm.

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

 According to Sars 3 ) the species is mentioned from Finmark by Mr. 

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



Friele and Grieg 4 ) 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 



'i (s) means that only empty >lielN were found.
