1949, I specimen; and in 138 feet, 3.5 miles out, August i, 1950, 

 I specimen. At Point Barrow base, summer 1951, 3 specimens, and

This is a rather common Arctic and North Atlantic species. In the

Family AMPELISCIDAE 



AMPELISCA MACROCEPHALA Lilljeborg 



Ampelisca macrocephala Sars, 1890, p. 172, pi. 60, fig. i. — Stebbing, 1906, p. 

 loi. — Stephensen, 193s, p. 123; 1944b, p. 48. 



Material collected. — In 162 feet, 3.2 miles out, February 18, 1950, 

 I specimen. 



Dr. Stephensen says that this is a widely distributed circumpolar 

 species, and occurs in the Atlantic at Jamaica Bay, Long Island, 

 N. Y. ; southern Greenland ; northern Iceland ; and the Danish waters. 



In the U. S. National Museum there are specimens of this species 

 from the Bay of Fundy and Delaware on the east coast of America, 

 and off San Diego, Calif., on the west coast. K, H. Barnard (1932, 

 p. 82) has recorded specimens from South Georgia which he says 

 are extraordinarily close to macrocephala Lillj., and which he has 

 identified as that species. Dr. A. Schellenberg has described two forms 

 of A. macrocephala from the South Pacific (1931, pp. 52 and 53). 



The present specimen from Point Barrow is a male measuring 

 26 mm. This species has been recorded between 350 and 400 m.

Material collected. — In 100 feet, August 21, 1948, i specimen. 

 Washed ashore at Point Barrow base, October 16, 1949, i specimen. 

 Taken under ice along shore ^ mile south of base, November 20, 

 1949, I specimen. 



Dr. Stephensen says that this is a widely distributed circumpolar 

 species ; also in the Atlantic with adjacent waters north of a line from 

 northern United States, southern Greenland, southern Iceland and 

 Faroe Channel to West Norway; and two hauls south and east of 

 Ireland.
