Bathylychnops exilis Cohen, 1958. Javelin Spookfish. To 58 cm (22.8 in) SL (Parin et al. 1995). Atlantic
and Pacific; Japan (Fujii in Masuda et al. 1984) to Kuril Islands (Parin et al. 1995) to British Columbia
(Gillespie 1993) to at least as far south as Isla Guadalupe, central Baja California (SIO 67-67); also
reported from Chile (21º27'S; SIO 72-177). Bathypelagic, at about 400–800 m (1,312–2,625 ft) (min.:
Nakabo 2002; max.: Lavenberg and Ebeling 1967).
Dolichopteryx longipes (Vaillant, 1888). Brownsnout Spookfish. To 18 cm (7.1 in) SL (Berry and Perkins
1966). Circumglobal in temperate and tropical waters; southern California (Berry and Perkins 1966) to
Chile (Pequeño 1989). Pelagic, at 152–1,139 m (500–3,737 ft) (min.: Eschmeyer and Herald 1983; max.:
Lauth 2001).
Dolichopteryx parini Kobyliansky & Fedorov, 2001. Winged Spookfish. To 21.7 cm (8.5 in) SL. Possibly
throughout the North Pacific; recorded from Pacific off Honshu, Japan and Sea of Okhotsk to southern
Bering Sea to southern British Columbia. Mesopelagic, at depths of about 200–1,000 m (656–3,281 ft),
possibly shallower. All in Mecklenburg et al. (2002); the authors listed and commented on records in
addition to those given by Kobyliansky and Fedorov (2001).
Macropinna microstoma Chapman, 1939. Barreleye. To 16 cm (6.3 in) TL (Mecklenburg et al. 2002). Western
North Pacific off northern Japan and Kuril Islands to Bering Sea and Gulf of Alaska to eastern South
Pacific west of Islas Juan Fernández, Chile (Mecklenburg et al. 2002). Primarily mesopelagic, range
16–1,015 m (53–3,330 ft; Mecklenburg et al. 2002), and perhaps to 1,267 m (4,157 ft; Lauth 2001).
Opisthoproctus soleatus Vaillant, 1888. Shortnose Flatironfish. To about 10.5 cm (4.1 in) TL (Quéro in
Quéro et al. 1990). Circumtropical; off San Diego, southern California (32°N, 124°W; SIO 88-43) to
Chile (Pequeño 1989). Pelagic, at about 300–800 m (984–2,625 ft; Quéro in Quéro et al. 1990).
Family Alepocephalidae — Slickheads
Alepocephalus tenebrosus Gilbert, 1892. California Slickhead. To 61 cm (24 in) TL (Fitch and Lavenberg
1968). West of Barkley Sound, British Columbia (Peden 1997) to at least Isla Guadalupe, central Baja
California and also reported from Chile (Ambrose in Moser 1996). Reports from eastern Bering Sea
not verifiable (Mecklenburg et al. 2002). Benthopelagic, at depths of 294–1,646 m (965–5,432 ft) (min.:
Grinols and Heyamoto 1965; max.: Alton 1972). Mecklenburg et al. (2002) give that range, noting that
although greater extremes of depth have been reported they are not verifiable, and that the depth range
of 46–5,486 m (150–18,000 ft) given by Fitch and Lavenberg (1968) may apply to the family as a whole
and not necessarily to A. tenebrosus.
Asquamiceps pacificus Parr, 1954. To 8.5 cm (3.4 in) SL (Parr 1954). Off Bahia San Cristobal, southern Baja
California (27°07'N, 115°08'W; Markle 1980) to Gulf of Panama (Parr 1954). Deep water.

1984). Circumtropical; off southern Baja California (Markle 1980). At depths of 1,300–3,660 m (4,290–
12,004 ft; Markle and Quéro in Whitehead et al. 1984).
Bajacalifornia burragei Townsend & Nichols, 1925. Sharpchin Slickhead. To 19.8 cm (7.8 in) SL (Childress
et al. 1980). Southern California (about 34°N; Ambrose in Moser 1996) to Chile (23°51'S, 71°01'W;
