(Casanova, 1976); the Faroes; south and west off
Iceland; Irminger Sea; off West Greenland from ca.
64° 30’ N (once at 70° N) to off the U.S.A. east coast
between 41° 35’ N and 33° 42’ N (Stephensen, 1935);
and off Montevideo, Uruguay.
Atlantic depth range: (10-) 100-900 (-1200) m, upper
mesopelagic (Omori, 1974; Hargreaves, 1985), strong
vertical migrant (Hargreaves, 1985: table 1, fig. 6).

1902), 61° 08’ N, 9° 46’ W, 847 m, 3 specimens; Stn
102 (1910), 60° 57’ N, 4° 38’ W, pelagic haul from
750 m, 2 immature specimens (Sund, 1920). »Thor« at
59° 49’ N, 9° 46’ W (Hansen, 1908).
BIOFAR stations: 810. The specimens were probably
caught in the water column.

stn).
Atlantic distribution: In addition to the localities
mentioned it has been recorded from Bay of Biscay
(Casanova, 1976) to 29° S, Namibia (Macpherson,
1991); westem Mediterranean (Casanova, 1976); off
the east coast of U.S.A from 41° 20’ N to 34° 28’ N

Atlantic depth range: It has been caught in the water
column in 100 - 900 (-1150) m over bottoms at depths
of 680 to 4707 m (Hansen, 1908; Kemp, 1910), lower
mesopelagic, short-distance migrant (Omori, 1974).
