Herviera gliriella (Melvill &
Standen,
1896)

Maximum size: 2.5 mm shell
length.
Identification:
The
shell
of this species is ovate with prominent axial ribs. It has
five whorls when mature and the apex and base are dark brown,
contrasting with the light brown of the remainder of the shell. The
axial ribs increase in size gradually at the transition between the
protoconch and teleoconch. That trait and its color distinguish it from
Herviera sp. #1. The two-toned
color and fewer axial ribs distinguish it from Herviera
sp. #2. The animal is cream with white flecks.
Natural history:
Shells
of
Herviera gliriella
are moderately rare in beach drift. Live animals are found occasionally
in shallow rocky habitats.
Distribution:
Maui, Oahu, French Frigate Shoals and Midway.
Taxonomic notes:
The
description
of this species in Kay, 1979 suggests that she was not
distinguishing H. gliriella
from H. sp. #1 and H. sp. #2. Her photo is clearly of
the above species but type material will probably need to be checked to
confirm which is the "real" H.
gliriella. The shell illustrated as H. gliriella in Severns, 2011 is this species.
