DISTRIBUTION. — Collected in New Caledonia, Fiji and Tonga (Fig. 14), in 614-960 m.
DESCRIPTION. — Shell morphology. Length 10 mm, width 5 mm (holotype). Shell thin, elongate, with convex sides (Fig. 13A). Body whorl large, about 2/3 of the shell length. Spire very elongate, conical, with 3-4 long whorls. Suture channeled. The protoconch was eroded in all shells examined. Umbilicus closed. Aperture short narrow, wider anteriorly, about 2/3 of the body whorl length. Columellar margin thickened, slightly oblique, with a small, inconspicuous fold. Sculpture of a number of punctuated spiral grooves (Fig. 11C). The punctuations are small, elongate, and partially fused together within each groove. The grooves are separated by gaps that are several times wider than the grooves. Colour uniformly whitish.
Anatomy. Unknown. All shells collected lacked soft parts.
REMARKS. — “ Acteon ” editus has a different shell morphology from other Indo-Pacific species of Acteonidae . Punctacteon amakusaensis Habe, 1961 from Japan, illustrated by Hori (2000a) also has a high spire, but the sculpture is much stronger with fewer grooves and a proportionately smaller aperture.
A definitive generic placement for this species is not possible until complete specimens become available for study.
ETYMOLOGY. — From the Latin editus (high, lofty), in reference to the high spire of this species.
