The Mollusca Collection of the Museu Nacional (acronym MNRJ), one of the most important of its kind in South America, holds more than 40,000 registered lots and about 15,000 unregistered lots, which are currently being processed, including dry shells and preserved specimens from Brazilian and foreign provenance. Most lots are from Brazilian localities, but several lots from other coutries are also present, specially from South America. Species from marine and non marine habitats are represented, as well as molluscs from sambaquis. The type material stems from studies carried out since the beginning of the 20th century by Brazilian and foreign researchers. A total of 683 type lots are currently deposited.
