Origin of anal fin behind vertical through base of last dorsal ray. Origin of adipose fin slightly behind vertical through base of last anal ray. Pectoral fin not reaching base of ventral fin; ventral fin not reaching anal Fig. 6. Diaphus jenseni (SM 183). Scale 10 mm. Dn small, heart-shaped and directed anterolateral^; Vn about same size as Dn, situated at anteroventral margin of orbit. Ant present, dorsad to Dn. Opi small and about opposite posterior end of maxilla; Op2 larger than general body photophore, situated above Opi and at about level of ventral margin of orbit. PLO much nearer to upper base of pectoral fin than to lateral line. VLO about equidistant between outer base of ventral fin and lateral line. SAO series slightly angulate, with SAOi in line with V04 and VOs, but well behind VOs, with SAO2 above anus at about level of V02, and with SAO3 slightly behind vertical through SAO2 and about 1,5 times its diameter below lateral line. AOa1 abruptly elevated, above level of SAO2; AOa2-AOa3 interspace enlarged; no AOp photophores above base of anal. Pol under origin of adipose fin, about 1,5 times its diameter below lateral line. Pre series arched, with Prc3-Prc4 interspace enlarged; Prc4 about its own diameter below level of lateral line. A large lumi- nous scale at PLO. Maximum length 50 mm; sexually mature from about 31 mm. Distribution Indian Ocean: between 05°N and 12°S, but more common west of 75°E; south-east Asian seas. Pacific Ocean: central and western tropical waters to about 35°N in Kuroshio Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of
