Marquise Marianna Panciatichi Ximenes d’Aragona Paulucci (3 February 1835 – 7 December 1919) was an Italian malacologist who also made contributions to botany and ornithology.
[1][2] A specialist in non-marine molluscs,[3] she published 32 malacological works, describing two genera and 159 species,[4] and is commemorated in around 40 scientific names of organisms: primarily molluscs, as well as the fossil shark Scyllium pauluccii and the bird subspecies Sylvia atricapilla pauluccii.
[5] She was born in Florence into a noble family: the daughter of Ferdinando Panciatichi Ximenes d'Aragona [it] and Giulia De Saint Seigne.
[7] In 1887, after her husband's death, and ten years after her father died, the Marquise had to abandon her studies as well as her collections so she could devote her energies almost entirely to the administration of her significant family affairs.
[7] Her herb collection of 4,153 specimens belonging to 1,492 different species was donated to the Galileo Galilei Technical Institute.
