Professional restoration in the lower right corner of the first 3 pages. Plates have scattered foxing. Some light foxing thourough. A research trip to the North German coast and its islands, undertaken together with H. Frey, prompted him to publish his observations with him: "Contributions to the knowledge of invertebrates with particular regard to the fauna of the North German sea". In this book Leuckart indicated that Cuvier's Radiata types were not enough. Successively he divided Cuvier's Radiata into coelenterates and echinoderms based on anatomical and developmental relationships. Huxley describes this division as the most important advance in animal systematics since Linnaeus.
