324 Neogene paleontology in the northern Dominican Republic: 2. The genus Strombina (Gastropoda: Columbellidae)

Ten species of Strombina are discussed and their type specimens refigured. S. cyphonotus and S. prisma, two species belonging to the subgenus Strombina, although always listed in Dominican faunas, in all probability do not occur in the Dominican Republic at all. The stratigraphic range and the mode of occurrence of the remaining eight species is indicated. One subgenus (Spiralta) and one species (S. canae) are described as new. The subgenus Sincola dominates the fauna both in number of species and in numbers of individuals. The subgenus Bifurcium is represented by two species, and the subgenus Spiralta by one.
