Findested. Beeren Hiland, 18 fv. 
Arten er udbredt fra Murmankysten til Middelhavet, 
Adriaterhavet, Madeira og Canariske ger. Inden den ark- 
tiske region er det dog blot varieteten interrupta, som op- 
ireder. Den bathymetriske udbredelse er O—1785 fy. 
Denne sidstnævnte dybde er angivet af ,Travailleur*, men 
gjælder neppe levende exemplarer. Fossil er den funden 
i Skandinavien, Britiske øer, Frankrig, Italien og Rhodes. 
Locality. Bear Island (18 fathoms). 
This species is distributed from the Murman Coast 
to the Mediterranean, the Adriatic, Madeira, and the Ca- 
nary Isles. In the arctic regions, however, only the variety 
interrupta occurs. Its bathymetrical distribution is from 
0 to 1785 fathoms. This last mentioned depths is noted 
by 'Travailleur”, but dos scarcely reffer to living specimens. 
It is a fossil in Scandinavia, the British Isles, France, 
Italy, and Rhodes.
