Character:

Origin of dorsal fin over base of ventral fin. Origin of anal fin under end of base of dorsal fin. Pectoral fins long, extending to third or fourth AOa. Ventral fins reaching origin of anal fin. Base of adipose fin over end of base of anal fin or slightly in advance of it. A small, roundish Vn immediately posteroventrad to nasal apparatus. Op1 a little below level of posterior end of upper jaw; Op2 about over Op1 and at level of ventral margin of orbit or slightly higher. PLO immediately below lateral line. PVO1 somewhat in advance of PO2, rarely directly over it; PVO2 immediately in front of upper half of base of pectoral fin and behind a straight line connecting PVO1 with PLO. Five PO; PO1 through PO4 level: PO5 abruptly displaced dorsolaterlly, lying in front of base of outermost ray of ventral fin. VLO midway between base of ventral fin and lateral line or slightly lower. Five VO; VO1 through VO4 forming a pronounced arc; VO5 abruptly elevated. SAO usually somewhat angulated, rarely on a straight line; SAO1 over and slightly behind VO5, in front of line connecting VO5 with SAO2; SAO2 usually somewhat behind line connecting SAO1 with SAO3, the latter lying about over origin of anal fin and in contact with lateral line. First AOa usually depressed, last AOa slightly raised. AOp evenly spaced and level. Pol2 under base of adipose fin and in contact with lateral line. Four Prc; Prc1 through Prc3 evenly spaced, forming a gentle arc; prc4 well behind and far above Prc3, at level of lateral line. A triangulsr or crescent-shaped patch between PLO and base of pectoral fin; a vertically elongated patch between PVO1 and PVO2; three to four irregularly-shaped patches within the triangle formed by PVO1, PO1 and PO2; similar luminous structures anterodorsad to PO3 and anterodorsad to PO4; small patches over base of ventral fin and over origan of anal fin. A rather large, triangular –apex directed forward—luminous patch midventrally, slightly in front of, and between bases of ventral fins; a series of four luminous scales midventrally, extending from VO1 to anus; a similar, but smaller luminous scales in each side of and close above the anus, behind the elevated VO5; two to five luminous scales along base of anal fin; a series of seven to eight infracaudal luminous scales extending from immediately behind end of base of anal fin to anteriormost procurrent caudal ray; four to five similar but smaller scales at bases of ventral procurrent rays, usually extending to vertical through Prc4; three to four, rarely two, median luminous scales in front of anteriormost dorsal procurrent caudal ray; three paris of similar but smaller scales at base of dorsal procurrent caudal rays, extending to vertical through Prc4; four to seven triangular—apex directed posteriorly—luminous scales mid-dorsally between end of base of dorsal fin and base of adipose fin; four to eight similar structures mid-dorsally, in front of dorsal fin, progressively smaller with distance from dorsal fin; a series of three to seven luminous patches—sometimes only one—along base of dorsal fin, or somewhat below and parallel to it; one or two longitudinal series of small, roundish patches above and parallel to lateral line, extending from behind head to about vertical through origin of dorsal fin.

Habitat:

Oceanic species fouetween 700 and 1,500 m during the day; between 20 and 200 m at night with maximum abundance between 50 and 100 m. Size stratification with depth both day and night. Small juveniles (1.5-1.9 cm) are apparently non-migratory. Known to fee
