THE REVISION OF THE GENUS ELONGOBULA-FINLAY, 1939

The genus Elongobula Finlay is removed from the vicinity of Buliminoid es and reclassified in the Orthoplectidae, Buliminacea, because its ty pe species E. chattonensis possesses a toothplate, besides being troch ospiral with a clearly defined seriality. The revision of Buliminella showed that this genus is characterised by a closed periapertural lip and the absence of a toothplate. Species classified in Buliminella, wi th an apertural flap and furrowed apertural face, left without generic attribution after the redefinition of Buliminella are revised and rec lassified in Elongobula. The revision results in the designation of va rious lectotypes and in the creation of the new species E. andromachae , E. arethusae, E. electrae, E. iphigeneae, E. medeae, and the new nam e E. lecalvezae. Elongobula is included with Floresina and Orthoplecta in the Orthoplectidae because of the similar high seriality, grooved apertural face and apertural flap and toothplate shape.
