Pyramidella sulcata A. Adams, 1854
Maximum size: 28 mm shell
length (Severns, 2000).
Identification:
Shells
of this species are straight-sided with deep sutures and
irregular brown blotches. Young shells have folds inside the outer lip
that are not visible in mature shells. Live animals are cream, frosted
with white flecks.
Natural history:
Shells
of Pyramidella sulcata
are moderately rare in beach drift. It's a nocturnal sand-dweller
that's occasionally found
in mixed, back reef habitats at about 1 m (3 ft) as well as in sand
samples
from Halimeda kanaloana beds
taken at depths of around 10-20 m (33-66 ft). According to Kay (1979),
it occurs in depths of up to 100 m (328 ft).
Distribution:
Maui, Oahu, Kauai and Midway (also Johnston Atoll): widely distributed in the Indo-Pacific.
Taxonomic notes: This species is probably also listed in Severns, 2011 as Syrnola cf. translucida (Laseron, 1959) (in our opinion, the illustrated shell falls within the range of variation for young P. sulcata). It's also mis-labelled as Pyramidella dolabrata in Kay & Schoenberg-Dole, 1991.
