Nesiodostomia quarta
(Pilsbry, 1918)
 
Nesiodostomia quarta: shell
Maximum size:  3.4 mm shell length (Kay, 1979).

Identification:  Shells of this species are slender, straight-sided and tapered. The protoconch is consistently smaller that in the shell of the similar-appearing Nesiodostomia sp. #1.

Natural history:  Although Kay (1979) lists Nesiodostomia quarta as a rare species with shells found in sand samples from about 10 m (33 ft), its shells are moderately common in beach drift on Maui.

Distribution:  Maui and Oahu.

Taxonomic notes:  This species is listed in Severns, 2011 as Eulimella quarta.
