DISTRIBUTION. — North of New Caledonia, in 502-527 m, and Tonga, in 416-444 m (shells only).

DESCRIPTION. — Shell up to 78.7 mm long, regularly curved, shiny, light orange. Ten ribs hardly observable at apex, absent on ventral side, obvious on dorsal side until the middle of shell, all vanishing towards mouth. Growth lines are dense and irregular, sligthly wavy not straight. Section very slightly depressed dorsoventrally. Apical thin, circular in section, with a shallow notch on ventral side.

Measurements of holotype: L 78.9, W 4.2-4.1, w 0.6, arc 6.

REMARKS. — Compared to A. alis (described above) A. maestratii is more curved and tapering, colored and almost translucent. Antalis maestratii seems to represent an extreme form within Antalis , in which the ribs are present only on the dorsal side, vanishing early before the middle of shell.

ETYMOLOGY. — Named after Philippe Maestrati (MNHN), who dedicatedly processed most of the material described here, and offered continuous support during the author’s visits to the MNHN.
