MYSIDACEA (CRUSTACEA) IN THE FAROE AREA

Atlantic depth range: 240 - ca 2500 m, benthopelagic

(Fossá, 1985; Mauchline, 1986; Fossá and Brattegard,

1990).

Boreomysis megalops G. O. Sars, 1872

Good description: Tattersall and Tattersall (1951: 135,

figs. 21C, 23A, 24).

Previous records: None.

BIOFAR stations: 690, 9004. The single specimens

caught in each of the detritus sledge stns 496 and 516

may have been caught in the water column.

Area: The top and slope of Lousy Bank.

Depth range: 302 - 357 m (515 m ?, 914 m ?).

Temperature: measured at 2 stns, 7.9 °C; estimated

range 5.9 - 9.4 °C.

Water mass: AW (2 stns).

Bottom type: Soft bottom, fine shell-sand.

Atlantic distribution: From Finnmark, Norway to Bay

of Biscay; the Faroes; the western Mediterranean and

Adriatic Sea (Hoenigman, 1963).

Atlantic depth range: 20 - 700 m, hyperbenthic (Fossá

and Brattegard, 1990; T. Brattegard, unpublished).

Boreomysis microps G. O. Sars, 1883.

Synonym: Boreomysis subpellucida Hansen (1905).

Good description: Tattersall and Tattersall (1951: 138,

figs. 21D, 23B, 25).

Previous records: »Thor«, 61° 08' N, 9° 28' W, 820 m

(Hansen, 1908).

BIOFAR stations: 67, 412, 417.

Areas: The western slope of Lousy Bank, northwest of

the Faroe Bank, and on the southern slope of the

Faroe-Iceland ridge.

Depthrange: 820- 1144 m.

Temperature: measured at one stn, 3.5 °C; estimated

range 0.6 - 7.5 °C.

Water masses: AW (1 stns) and AW/AI (3 stns).

Bottom type: Soft bottom.

Atlantic distribution: According to Mauchline and

Murano (1977) the species is confined to the Atlantic

between 64° N (off Kristiansund, Norway) and 40° S,

but it is also reported from the Faroes; west of Iceland

(66° N; Astthorsson, 1985) and Baffin Bay (Dunbar

and Moore, 1980).

Atlantic depth range: 200 - >3500 (3710) m,

bathypelagic (Astthorsson, 1984; Hargreaves, 1985b;

Mauchline 1986); populations may impinge on the

slopes (Hargreaves, 1985b).

Boreomysis nobilis G. O. Sars, 1885

Good description: Sars (1885: 54, pl. 5, figs. 22-28).

Previous records: »Ingolf« Expedition: Stn 138, 63°

26' N, 7° 56' W, 885 m; Stn 139, 63° 36' N, 7° 30 W,

1320 m; Stn 141, 63° 22' N, 6° 58' W, 1277 m

(Hansen, 1908).

BIOFAR stations: 41, 169, 227, 427, 563, 713, 715,

804, 805, 9009.

Areas: In cold water on the northern slope of the

Faroe-Iceland Ridge, north of the Faroes, and the

eastern slope of the Faroe shelf towards the Faroe-

Shetland Channel.

Depth range: 505 - 1320 m.

Temperature: measured at 9 stns, -0.85 to -0.1 °C.

Watermasses: AI/NW (1 stn), AI (1 stn), and NW (11

stns).

Bottom type: Soft bottom.

Atlantic distribution: The Faroes; Norwegian Sea;

north of Iceland; East Greenland; Baffin Bay (75° N)

and eastern waters of Canada: Saguenay fjord (Judkins

and Wright, 1974) and Bonne Bay (Dunbar et al,

1980), St. Lawrence estuary, and some cold water

localities off Newfoundland (Dunbar and Moore, 1980;

Richard and Haedrich, 1991).

Atlantic depth range: 505 - 1410 m (Hansen, 1908),

probably mesopelagic.

Boreomysis scyphops G. O.Sars, 1885

Good description: Sars (1885: 56, pl. 6, figs. 1-22);

Hansen(1908:99).

Previous records: »Ingolf« Expedition, Stn 140, 63°

29' N, 6° 57' W, 1466 m (Hansen, 1908).

BIOFAR stations: 564, 9001, 9007, 9008, 9019.

Areas: The deep waters north of the Faroes and Faroe-

Shetland Channel (Fig. 10).

Depth range: 1338 - 2420 m.

Temperature: measured at 6 stns, -0.94 to -0.7 °C.

Water mass: NW.

Bottom type: Soft bottom.

Atlantic distribution: Restricted to the Norwegian Sea

(see Hansen, 1908; Tattersall, W. M., 1951; Tattersall,

O S., 1955); the Faroes. Gordan (1957), Mauchline

and Murano (1977) and Mauchline (1980; 1986)

include B. scyphops in B. inermis (Willemoes-Suhm,

1876).

Atlantic depth range: 980 - 3570 m, probably

benthopelagic (T. Brattegard, unpublished).
