Notes on some freshwater molluscs from Nariva Swamp, Trinidad

Peter R. Bacon


Study of published literature on the freshwater mollusca of Trinidad and Tobago revealed a paucity of infonnation on their distribution and ecology. Several papers exist giving species records and taxonomic data but, as most of these were written during the last century, the taxonomy is in need of revision. In 1977 the Zoology Department, University of the West Indies, began investigations of the fauna of the Nariva Swamp and collected a number of shellfish. Detailed taxonomic and ecological studies of these species are in progress, but some preliminary notes are given here in the hope that local naturalists will be en· couraged to collect and study these poorly known freshwater animals.
