(unidentified Odostomia species - 9mm - on intertidal rocks - Port Hardy, BC)
Numerous members of the genus Odostomia inhabit coastal British Columbia.
The genus is poorly studied at the present time.
Kozloff (1987) lists 20 species for this region, and even these he states as questionable.
These snails are characteristically small, white and smooth-shelled, making identification
of specimens nearly impossible.
