Systellaspis debilis (A. Milne Edwards,
1881)
Synonym: Acanthephyra debilis A. Milne Edwards
(1881).
Good description: A. Milne Edwards (1881: 13, as
Acanthephyra debilis); Murray and Hjort (1912: 668,
pl. 3, fig. 3).
Previous records: None.
BIOFAR station: 704. The single, juvenile specimen
was probably caught in the water column because the
closing mechanism failed to close.
Area: Southwestern part of Faroe-Shetland Channel.
Depth: bottom depth at 1028 m.
Temperature: measured near bottom, -0.5 °C.
Bottom water mass: NW (1 stn).
Atlantic distribution: From south of Iceland and the
south-westem part of the Faroe-Shetland Channel (Stn
704) to 20° S, Namibia (Macpherson, 1991) and c. 33-
35° S, South Africa (Kensley, 1981); eastern Gulf of
Mexico (Flock and Hopkins, 1992).
Atlantic depth range: (10) 25-3000 m (Sivertsen and
Holthuis, 1956), usually 150-700 m (Omori, 1974),
meso- to bathypelagic, strong vertical migrant
(Hargreaves, 1985).
Family PASIPHAEIDAE
Genus Pasiphaea Savigny, 1816
Pasiphaea multidentata Esmark, 1866

Faroes (Sivertsen and Holthuis, 1956: fig. 21).
BIOFAR stations: 68, 69, 124, 806. The specimens
were probably caught in the water column.
Areas: Northwest and east of Faroe Bank, the top and
southem slope of Faroe-Iceland Ridge.
Depth range: bottom depths at 300-1100 m .
Temperature: measured near bottom at one stn, 8.1 °C;
estimated range 1 - 9 °C.
Bottom water masses: AW (3 stns), AW/AI (1 stn),
and AI (1 stn).

southwards to Marocco; Mediterranean (Sivertsen and
Holthuis, 1956; Casanova, 1976); the Faroes; south off
Iceland; southeast off Cape Farewell, Greenland; from

Atlantic depth range: 10-2000 m, most frequent in 100-
500 m (Sivertsen and Holthuis, 1956), benthopelagic
and performs vertical feeding migrations (Lagardere,
1976).
