Harpa gracilis Broderip & Sowerby, 1829

Harpa gracilis is rare in the Marshall Islands, known from only a few empty shells found on the leeward seaward slope at depths deeper than about 16m at both Kwajalein and Enewetak Atolls. Shells are thin and light, similar to the lighter-weight form of Harpa amouretta, but Harpa gracilis tends to be narrower for its length and the anterior end of its aperture flares out more. Also, the protoconch (tip of the spire) in Harpa gracilis is white, while that of Harpa amouretta is pink to purple.

No photos of living specimens are available.
