Abstract: Polyipnus aquavitus Baird, 1971 (Figures 18��19) 1999 Polyipnus aquavitus Rivaton J, Bourret P, pp. 208��209, pl.95 fig. 18��24 Material: 9 specimens in total. Anda1 (3) RGM 962117; Anda2 (1) RGM 962118; Anda4 (1) RGM 962119; AndaDeVos (1) RGM 962120; Roxas (2) RGM 962121, RGM 962122; Tiep2 (1) RGM 962123. Nine otoliths with the typical characteristics of Polyipnus were encountered (OL:OH=0.59��0.74 for the body). Fossil specimens of Polyipnus always have lost the long, very thin rostral part. The posterior rim of the better- preserved specimen has a lobed outline, a characteristic that has disappeared in eroded specimens. Comparison of the specimens with a range of different Polyipnus species (courtesy of D. Nolf) suggested that the specimens match with P. aquavitus, which is also known form the western Pacific Ocean.<br />Published as part of Van Hinsbergh, Victor W.
