This first edition, folio shell engraving is from Niccolo Gualtieri’s Index testarum conchyliorum quae adservantur in museo Nicolai Gualtieri. The work was published in Florence by C. Albizzini in 1742. The plates were engraved by Antonio Pazzi & Giuseppe Menabuoni.
Gualtieri was an Italian physician and naturalist. Many of the images in the work were from his personal and renowned collection of shells. Linnaeus used many of Gualtieri’s speciments for his Systema Naturae..
