"Set of feather artifacts, part of the Mundurukú collection, sent in 1830 to the Museum in crates without a list of contents, probably coming from the collection of the Langsdorff Expedition, since several crates with pieces collected by this expedition were in the state of Pará to be sent in By comparing the habits described in the travel diary of the French polygrapher and designer Hercule Florence, one can link this collection to the Mundurukú de Santarém in 1829. There is also, in a document from the General Archives of the National Museum, the Information that the crates sent without a list were classified by Antonio Correia de Lacerda.
