Odostomia
cf. oxia
Watson, 1886
 
Odostomia cf. oxia: shell
Maximum size:  3.7 mm shell length.

Identification:  Shells of this species are glossy-white with smooth whorls. Occasionally, they are more elongate adding additional whorls (sometimes with distortion of the axis of coiling in atypical examples). Most have relatively thick shells.

Natural history:  Shells of Odostomia cf. oxia are moderately common in beach drift.

Distribution:  Maui, Oahu, French Frigate Shoals and Midway.

Taxonomic notes:  The shell illustrated as Odostomia oxia in Kay, 1979 appears to be a small specimen of this species. The shell illustrated as Odostomia gulicki in Severns, 2011 is this species but the shell labelled Odostomia gulicki in Pilsbry, 1918 probably isn't. Odostomia cf. oxia is probably also listed in Severns, 2011 as Odostomia montforti Corgan, 1972 although Corgan proposed that name as a replacement name for Odostomia secunda (illustrated as Eulimella secunda in Severns, 2011).
