Notes on Some Freshwater Molluscs from Nariva Swamp, Trinidad

Abstract

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 encouraged to collect and study these poorly known freshwater animals.
