caption: The image shows a close up of two white seashells on a black background, with the text "Laskeyia Onchodia Benthica Dall, 1924 USNM 108344 Holotype" at the top. The shells have a smooth, glossy finish and are arranged in a symmetrical pattern, with one shell slightly overlapping the other. The background is a deep black color, providing a stark contrast to the white shells.
