Characteristic	D. 15(14); A. 15(14); P. 10-11; G.R. 6 (5-7) +1 + 13 (12-14), total 20 (18-21); AO 6 (5) + 5 (6) Operculum somewhat angular posterodorsally, attenuated to a sharp point posteriotly. Origin of dorsal fin in advance of base of ventral fin. Origin of anal fin behind end of base of dorsal fin. Pectoral fins extending about to PO5. Ventral fins reaching anus. Base of adipose fin over end of base of anal fin. Dn immediately posterodorsad to nasal apparatus, lentil-shaped and smaller than a body photophore. Vn massive, roughly crescent-shaped, along anterior and anteroventral margin of eye, in contact with Dn dorsally, terminating in advance of vertical through anterior margin of pupil ventrally. A broad, massive band of dark tissue obscuring Dn and much of Vn from lateral view. PLO 2-2.5 times as close to base of pectoral fin as to lateral line. VLO nearly twice as close to base of ventral fin as to lateral line. SAO on a straight line or very nearly so; SAO3 on or slightly in fron of vertical through origin of anal fin and about 2.5 times its own diameter below lateral line. AOa1 about 1.5 times its diameter anterodorsad to AOa2; rest of organs of same series porgresively raised forming a gentle curve with Pol. Pol under or slightly in advance of base of adipose fin, 2-2.5 times its own diameter below lateral line and often continous with AOa. AOp behind base of anal fin. Prc froming an arc with Prc3-Prc4 interspace often distinctly enlarged; Prc4 about twice its diameter below lateral line. A luminous scale at PLO, its size 3-4 times that of a body photophores.
