The one small specimen of Cirratulus in the collection is apparently this 

 species. It is a small specimen measuring not more than 15 mm. in length. 

 It lacks all branchiae at present; but the scars show a group of seven special 

 branchiae on each side of the first setigerous segment to have been present. 

 The eye bands are conspicuous and of the typical form. The specimen at 

 present is dark brown. 



This is a widely distributed species known from Scandinavia, Finmark, 

 Greenland, Labrador, Siberia, and Bering sea, and from southward in the 

 Atlantic to the coasts of the United States and Great Britain.
