six ovate, marine snail shells. The shells are arched with a white septum (ledge) underneath (supports the internal organs) which extends approximately half the length of the aperture. The shells are light pink, but shell 21-041.4 is black with white horizontal streaks. The shells have one whorl and horizontal striations running across each shell. The shells have color bands and the shells are slightly textured. The shells are slightly curved dextrally with a ""D"" shaped aperture.
