Heliacus sterkii (Pilsbry &
Vanatta, 1908)
Maximum size:
7 mm shell diameter (Severns, 2000).
Identification:
The
shells
of this species are flat and brown, blotched with
cream. They may be distinguished from the shells of
Heliacus implexus
by their darker color, more numerous marginal brown
spots and the presence of three cords on the margin.
The animal is translucent gray with black and
opaque-white flecks.
Natural history:
Shells
of Heliacus sterkii
are moderately common in beach drift. Live animals
are occasionally found in shallow rocky habitats.
Distribution:
Maui, Kauai and French Frigate Shoals.
Taxonomic notes:
It's probably also listed as Heliacus sp. in Severns, 2011 (the
shell illustrated under that name appears to be a
worn specimen).
