Genus Ledella Verrill and Bush, 1897 Type-species Ledella bushae Warén, 1978. Warén (1978, 1981) contributed to the definition of the genus Ledella and its type-species (ICZN, 1985), referring to this genus species with a rather solid shell and hinge, a well-developed blunt rostration and a posteriorly inclined umbo. Warén (1978) also stated that ' Yoldiella may be separated [from Ledella ] by having a less rounded shell which is more compressed and has a less solid hinge'. However, there is a group of fossil and living European species which differs from the typical Ledella species in having a less inclined umbo and a slightly keeled and markedly pointed rostrum. These species should be more properly attributed to Ledella , rather than the confused genus Yoldiella . This group includes the living Ledella messanensis (Jeffreys, 1870), L. folini (Warén, 1878), probably also L. pustulosa (Jeffreys, 1876), and the Pleistocene L. rectidorsata (Seguenza, 1877), the Pliocene L. seminulum (Seguenza, 1877) and the Miocene L. peraffinis (Seguenza, 1877) and L. glabra Laghi and Palazzi, 1989. : Published as part of La Perna, R., 2004, The identity of Yoldia micrometrica Seguenza, 1877 and three new deep-sea protobranchs from the Mediterranean (Bivalvia), pp. 1045-1057 in Journal of Natural History 38 on page 1052 : {"references": ["WAREN, A., 1978, The taxonomy of some North Atlantic species referred to Ledella and Yoldiella (Bivalvia), Sarsia, 63, 213 - 119.", "WAREN, A., 1981, Ledella Verrill & Bush, 1987 (Mollusca, Bivalvia) proposed designation of type species Z.
