Origin of dorsal fin directly over of slightly in advance of base of ventral fin. Origin of anal fin behind base of dorsal fin. Pectoral fin extending to PO5. Ventral fin reaching anus. Base of adipose fin from directly over to somewhat in advance of end of base of anal fin. A roughtly or oval-shaped Ant. A round Dn, equal in size to or somewhat smaller than a body photophores. Vn large, roughly triangular occupying most of space between anteroventral margin of eye an upper jaw, extending odrsallly along anterior margin of eye to Dn with which it is in contact, termination ventrally at or behind vertical through anterior margin of pupil. Vn distinctly larger and more sharply defined in adult males than in females of comparable sizes. PLO 2-2.5 times as close to base of pectoral fin as to lateral line. VLO nearer to base of ventral fin than to lateral line, SAO on a straight line or very nearly so; SAO3 on or slightly in front of vertical through origin of anal fin and about 2.5-3 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.
