Harp shells

Harp shells (Harpa) are glossy, ribbed snails with strong axial ribs like the strings of a harp and rich brown-and-cream patterns; Harpa major, H. harpa and the rarer H. costata are the collector species. They are moderately priced and are prized for pattern and gloss. Fossil harps are rare.
