Nesiodostomia sp. #1
|Maximum size: 3.5 mm shell
shell of this species is straight sided and slender. It may be
distinguished from the shell of Nesiodostomia
quarta by its larger protoconch and straighter sides. Some
shells have similar protoconchs but are somewhat more inflated. (see photo).
sp. #1 are moderately common in beach drift. Live animals are
occasionally found in shallow rocky habitats.
Taxonomic notes: This species is listed in Severns, 2011 as Eulimella sp. 2. There's
some possibility that the more inflated shells may be a
separate species. However, they appear to intergrade sufficiently to
