Nesiodostomia montforti
Corgan, 1972
 
Nesiodostomia montforti: shell
Maximum size:  4 mm shell length (Kay, 1979).

Identification:  The shell of this species is slender with a deeper suture than the shell of Nesiodostomia quinta. Occasional shells have a disproportionately inflated ultimate whorl similar to the shell illustrated in Kay (1979).

Natural history:  Shells of Nesiodostomia montforti are moderately rare in beach drift.

Distribution:  Maui and Oahu.

Taxonomic notes:  Kay, 1979 lists Pilsbry's Odostomia seconda as a synonym of Nesiodostomia montforti Corgan, 1972. However, Severns, 2011, illustrates the latter species as Eulimella secunda while including a shell that is probably an Odostomia cf. oxia under the name Odostomia montforti Corgan, 1971. Corgan proposed the name N. montforti as a replacement for Odostomia secunda. The shell labelled Nesiodostomia montforti in Kay, 1979 is probably a worn  specimen of that species.
