This paper presents an inventory of the species of molluscs collected on the continental shelf and upper slopes (70–500 m depth) on the Pacific side of Colombia. In 2002, 39 trawl samples were taken on soft bottoms by the RV ARC ‘Malpelo’. Thirty-eight species of bivalves were collected, comprising living animals and dead collected shells. Information on abundance, Colombian distribution and depth range is provided. Thirty-four species represent the first records for the Colombian Pacific, significantly increasing the number of shelf and slope species known in the region.
