caption: The image shows a group of five seashells on a black background with the text "Pseudotrochus leai pilsby, 1933 holotype USNM 406885" written on it. The shells are arranged in a symmetrical pattern, with the largest shell in the center and two smaller shells on either side. The colors of the shells range from light brown to dark brown, with some having a glossy finish. The text is written in a bold, white font, making it stand out against the dark background.
