caption: The image shows four different types of shells, with the text "Pandora Carolinensis Bush, 1885, Holotype USNM 3501" at the top. The shells are arranged in a symmetrical pattern, with each one having a unique shape and texture. The colors range from light to dark, with some having a glossy finish and others having a matte finish. The text is written in a bold, black font, making it stand out against the light background.
