species are similar to
those of Odostomia cf. oxia but differ from
that species in that the protoconch rises well above the apical whorl,
the apical whorls are wider, the shell is usually thinner and the
spire is usually more slender.
shells of Odostomia cf.
gulicki are occasionally
found in beach drift. On Maui, we've found only a few shells in
subtidal sand samples from 1-9 m (3-30 ft).
Maui and Oahu (also Johnston Atoll?).
The shell illustrated as Odostomia gulicki
in Kay, 1979 appears to be this species and the original drawing of
that species in Pilsbry, 1918 also seems comparable (though somewhat
ambiguous). The slender form is listed as Odostomia loxocephala
(Pilsbry, 1918) in Severns, 2011 while that species is considered as an
indeterminate juvenile in Kay, 1979. The shell illustrated as Odostomia gulicki in Severns, 2011 is Odostomia cf. oxia. There's

separate species but, based on the limited sample, they seem to
