can at present be said with certainty.

Distribution. This species has been found in the Arc- 
tic ocean, Norwegian Sea and the North Atlantic. In the Nor- 
wegian fjords it is hitherto only known from the Ofotenfjord, 
where a solitary specimen was taken in 1899 at a depth of 300 
—350 m.'). According to. FARRAN, *) it is quite common off the 
west coast of Ireland, where it is regarded as »a permanent and 
characteristic member of the fauna of the district«. It appears, 
however, to be an arctic species, as its occurrence in polar waters 
can scarcely be ascribed to transport by the Atlantic current.
