2 Shell small (adult diameter <10 mm) and predominantly white, turbiniform; sculpture cancellate or foveolate Vaceuchelus
7 Shell trochiform and with coarsely cancellate sculpture; periphery almost stellate; outer lip with subterminal external varix; parietal callus expanded beyond aperture Pholidotrope
--Shell turbiniform-conical and with finely cancellate or beaded sculpture; periphery more or less evenly rounded; outer lip lacking external varix; parietal callus not expanded Herpetopoma (part)
Herpetopoma pruinosum (Marshall, 1979), from the Kermadec Ridge, is also similar but has a lower spire and a finer, more obviously cancellate sculpture.
The shell of Vaceuchelus species is small (length <10 mm), predominantly white and has a cancellate or foveolate sculpture.
The apical whorls are sculptured only with axial pliculae and subsequent whorls with both spiral cords and axial pliculae that interact to produce a cancellate or foveolate sculpture (not obviously beaded).
Diagnosis: Shell small, profile conical with narrowly indented suture; suture level with subperipheral cord; sculpture coarsely cancellate with scale-like projections on spiral cords; columella with a single basal tooth; interior of outer lip thickened and set with ridge-like denticles, that nearest columella largest and separated from basal columella tooth by a U-shaped notch; denticles do not extend into aperture as in-running ridges; umbilical and parietal region covered by glossy inductural callus shield; aperture obliquely tangential to base of last adult whorl; outer lip with low subterminal external varix; protoconch exsert.
informa McLean & Poorman, 1971, from Ecuador; however, this taxon evidently lacks diagonally cancellate protoconch sculpture.
As noted above, in Kermia the protoconch is initially smooth or spirally striated, but later whorls are diagonally cancellate. Nevertheless, it is possible that the two taxa may intergrade, as diagonally cancellate sculpture may only develop towards the termination of the protoconch.
le tracce delle cose che stanno per perdersi, per essere cancellate
nel paesaggio dall'ombra possente della Morte, sulle quali la coscienza invisibile che le osserva si piega con pietas per raccogliere le umili vestigia.
