Special bulletin
This 1892 Smithsonian bulletin from the United States National Museum, published by the Government Printing Office in Washington, D.C., is a scientific monograph on hydromedusae, aimed at zoologists and naturalists. Its plates are fine pen-and-ink line drawings of branching hydroid colonies, stalked cups, and reproductive sacs, all shaded with delicate hatching and set on plain cream pages with running headers, offering designers clean botanical-style linework and tidy plate-layout ideas.
