Pyramidella sulcata
A. Adams, 1854
 
Pyramidella sulcata
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: 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.
