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.

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. : 
Locatitizs.—Northwest Territories: Bernard harbour, Station 41, July 
‘20, 1915. Depth, about 10 meters. Ten specimens taken on a sandy bottom 
among Laminaria.

' Several specimens taken from the stomach of a large female bearded seal, 
Erignathus barbatus (Erxleben). 
Northwest Territories : Dolphin and Union strait : Cockburn point. Station 
370. 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 41f. August 
1, 1915. Depth, about 5 meters. Bottom, sandy mud with stones and brown 
alge. 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 branchiz, etc., being prominent.
