Vanuatu . MUSORSTOM 8: stn DW 1021, 17°43’S , 168°37’E , DISTRIBUTION. — North of New Caledonia , Vanuatu , live in 130-450 m . DESCRIPTION. — Shell up to 50 mm long, solid, polished, posterior 1/2 yellow-cream, anterior 1/2 translucent. Strongly curved. Six primary angle-edged ribs, the 3 distributed on the dorsal side being larger and further apart than those on the ventral side, giving a characteristic section shape to the posterior 3/4 of the shell; ribs less prominent near the aperture in mature specimens, aperture becoming subcircular. Secondary ribs present on the posterior 1/3 of the shell, disapearing earlier on the ventral side, giving a smooth, shiny surface to the aperture. Intercostal spaces smooth. Apex with short notch, section slightly irregularly compressed dorsoventrally. Measurements of holotype : L 50, W 3, w 0.7, arc 5 at 20 mm from apex. REMARKS. — Compared with P. rudoi Scarabino, 1995 , from the western Indian Ocean, P. kabati is more strongly curved ( 5 mm arc, vs . 2.8 mm in P. rudoi ), its colour is only obvious on the posterior 1/2, and it is less solid, more tapering and strongly sculptured. Both have a similar transverse section and their ribs weaken in the same manner. ETYMOLOGY. — Named after Alan Kabat, bibliographer extraordinaire and author with Gerhard Steiner of the reference list of scaphopod names ( Steiner & Kabat 2004 ).
