Vlyssis Aldrouandi philosophi, et medici Bononiensis De reliquis animalibus exanguibus libri quatuor : post mortem eius editi : nempe de mollibus, crustaceis, testaceis, et zoophytis
Aldrovandi's posthumous 1606 Bolognese natural history of invertebrates, mollusks, crustaceans and zoophytes, compiled by the physician-naturalist Ulisse Aldrovandi for scholars and naturalists. The woodcut shells are drawn in dense parallel and crosshatched lines on plain ground, showing spiral whorls, ridged surfaces and shell apertures, useful to a designer for shell and mollusk motifs built from hatching.
