Unidentified Pyramidellid #9
 
Unidentified Pyramidellid #9: shell
Maximum size:  2.9 mm shell length (probably larger based on fragments).

Identification:  The shell of this species is similar to that of Odostomia cf. gulicki but with a shallower suture and larger protoconch. It also has faint, fine spiral striae. The latter are reminiscent of Evalina spp. but its protoconch is much larger than the protoconchs of the known Hawaiian species of that genus.

Natural history:  Unidentified pyramidellid #9 is known from only a few shells found in subtidal sand samples from 1-9 m (3-30 ft).

Distribution:  Maui.

Taxonomic notes:  This species is listed in Severns, 2011 as Eulimella sp. 4. However, its placement seems ambiguous due to its relatively broad profile and fine spiral striae.
