Mid-lateral black line broad from tip of snout to end of caudal fin, bordered by white lines.

Ostorhinchus: from Greek, osteon = bone + from Greek, rhynchos = beak. In reference to the bony jaws, very much advanced and jagged, which take the place of the teeth.
bryx: from Greek, bryx, brychos = abyss. Referring to relatively deep water (146-155 m) from which it was collected.
