Seven species belonging to two genera of Cuspidariidae and two genera of Verticordiidae are described and figured. Five of them occur in the Neogene sections of the Dominican Republic and their stratigraphic occurrences are given. Two species of the verticordiid genus Trigonulina are known from the Recent fauna only: one from the Western Atlantic, the other from the Eastern Pacific. The latter is described as new (T. pacifica n. sp.). The two living species are discussed herein for comparative purposes. Out of the five fossil species, only two are well represented (Cardiomya islahispaniolae and Trigonulina bowdenensis). The remaining three species are known from very few specimens.
