caption: The image shows four different types of scallops on a black background, with the text "Pecten Phrygium dall, 1886 USNM 62352" written on it. The shells are arranged in a symmetrical pattern, with each one having a unique shape and texture. The colors of the shells range from light to dark, with some having a glossy finish and others having a matte finish. The text is written in a bold, white font, making it stand out against the dark background.
