Figures

Planche 1 issued from : T. Park in Antarct. Res. Ser. Washington, 1983, 39 (5). [p.353, Fig.22].
Female: habitus (lateral left side); b, last thoracic segments and urosome (dorsal); c, idem (lateral left side); d, forehead (dorsal); e, idem (lateral); f, rostrum (anterior); g, Mx1; h, Mxp; i, P1 (posterior); j, P2 (posterior); k, P3 (posterior); l, P5.

Nota: The specimens seem to agree well with Sars' (1925) descriptions and illustrations, however the distal end of the metasome in lateral view is round instead of being angular and the rostral rami in anterior view are not tapering into sharp points.
Planche 2 issued from : O. Tanaka & M. Omori in Publ. Sero Mar. Biol. Lab., 1992, 35 (4/5). [p.265, Fig.6].
Female (from Izu region, Japan): a, forehead (dorsal); b, idem (lateral); c, posterior part metasome and urosome (dorsal); d, idem (lateral left side); e, rostrum (anterior); f, Mx1; g, Mx2; h, Mxp; i, P1; j, right P5.

Nota: Park (1983) states that rostral rami have an obtuse distal end. However, in the present specimen rostrum has a pair of strong spines with a small filament at each apex.
Planche 3 Issued from: G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.XLI, figs.6-11].
Female: 6, habitus (dorsal); 7, idem (lateral left side); 8, forehead (lateral); 9, rostrum (frontal view); 10, Mxp; 11, P5.

Remarques

bathypélagique.
Sampling depth (Antarct.) : 0-1000 m.
Les localisations dans le Pacifique nécessitent une confirmation, bien que Tanaka & Omori (1992) ont bien indiqué cette espèce au Japon (Izu).
