Abietinaria filicula is a boreal species, rarely penetrating into arctic waters, nor does it enter 

 the warmer seas; its distribution is circumpolar. Within the area investigated (fig. LXIII) it is freqnent 



20om. 600m taoom. 1000m. 



Fig. LXIII. The distribution of Abietinaria filicula in 'the Northern Atlantic. 

 In the hatched regions the literature notes a common occurrence. 



off the west coast of Norway, and in the northern British waters; at the Faroe Islands it seems to 

 be rare, while on the other hand it is one of the commonest species in Iceland waters, albeit lacking 

 here along the north coast. About Greenland, Abietinaria filicula is very rare, and has only been 

 recorded with certainty once from the west coast, near Godthaab. It belongs to the littoral region, 

 but can quite exceptionally also move down into the abyssal, as for instance west of the Faroe Islands.
