Annotated catalogue of the types of Mollusc taxa described by the Marquise Marianna Panciatichi Ximenes d’Aragona Paulucci preserved at the Museum of Natural History of the University of Florence (Part one)

The Marquise Marianna Panciatichi Ximenes d’Aragona Paulucci (Florence, February 3, 1835 - Reggello, December 7, 1919), a naturalist of the second half of the nineteenth century, is principally known for her scientific publications, in particular for those on malacology. For the centennial of her death, a project has started for the creation of the type catalogue of the molluscs she described. The catalogue will be divided into four parts; in this contribution, the 41 taxa included in her first two works (Paulucci, 1866, 1878a) are given, in which new species and genera were described. Among these, nine names are included, up to now assigned to Benoit, but which, according to the ICZN, must be attributed to Paulucci.
