This review aims to present an updated checklist of scaphopods, based mainly on literature database. There is a total of 40 species (six families) for Brazil, including information about the distribution and bathymetric range of each taxon. We propose two synonyms with the aid of morphometry of the shell, for the genus Gadila: G. longa as junior synonym of G. elongata and G. robusta as junior synonym of G. pandionis.
