This, the common lugworm, is primarily a north Atlantic and Arctic form 

 occurring at Spitzbergen, Kara sea, about Iceland and Greenland, and south- 

 ward on the North American coast to New England and on the European to 

 Great Britain and Portugal. It also occurs rather rarely in the Mediterranean. 

 A specimen collected by Middendorf in eastern Siberia and identified by Grube 

 (1851) as A. piscatorum, is with little doubt the present species, which seems 

 thus to have a circumpolar distribution. It is supplanted in the north Pacific 

 by A. pusilla Quatrefages. It is somewhat doubtfully recorded from Chile, 

 the Marquesas, etc., in the southern Pacific. 



LOCALITY. Northwest Territories: Bernard harbour. Station 49/i. June 

 17, 1916. 



A single specimen of the species was taken from the stomach of an 8 75 

 inches long sculpin, Cottus sp., caught in about 2 fathoms of water.

Many large specimens of this species were secured. It is a form common 

 on the shores of Greenland and is known to occur as well at Iceland, Spitzbergen, 

 Scandinavia, Finmark and Bering sea, and southward along the coasts of 

 North America to the northern shores of the United States and along the Euro- 

 pean shore to Ireland. 



LOCALITIES. Northwest Territories : Bernard harbour, Station 41, July 

 20, 1915. Depth, about 10 meters. Ten specimens taken on a sandy bottom 

 among Lammaria. 



Northwest Territories : Bernard harbour. Station 42e. September 3, 1915. 

 Several specimens taken from the stomach of a large female bearded seal, 

 Erignathus barbatus (Erxleben). 



Northwest Territories : Dolphin and Union strait : Cockburn point. Station 

 37o. October 3, 1914. Many specimens were taken at this station from the 

 stomach of a male Erignathus barbatus (Erxleben), 73 inches long. 



Northwest Territories : Bernard harbour, outer part. Station 4 1/. August 

 1, 1915. Depth, about 5 meters. Bottom, sandy mud with stones and brown 

 algse. One small specimen (18 mm. long.) A colored sketch of this specimen 

 made in the field by Mr. Johansen shows that in life the colors were essentially 

 typical, the green branchiae, etc., being prominent.
