nana, Eulima [ Nanobalcis nana (Monterosato, 1878) ] ( Figures 18S, T )

1875b: 35 [XIII: 261]—nomen nudum

1878a: 153 [XX: 443]—available name

Type material. MCZR–M–30023 —5 sh “ E. nana Monts Pal. — giugno 1873 ”.

Type locality. Described from Palermo (Sicily).

Remarks. First cited as a nomen nudum (Monterosato, 1875b: 35), then made available by a description in Monterosato (1878a: 153). It is the type species by original designation of the genus Nanobalcis Warén & Mifsud, 1990 , parasitic on cidaroid sea urchins ( Warén & Mifsud, 1990). We have discovered in an unnumbered box (now numbered 30023) the lot of five type shells, labelled by Monterosato as collected in Palermo in June 1873. Recorded by MolluscaBase (2018) as Nanobalcis nana (Monterosato, 1878)

pernula, Acicularia [Melanella pernula (Monterosato, 1890)]

1890b: 159 [XXXVIIIb: 907]—available name

Type material. Not found

Type locality. Described from Mondello (Sicily), Algiers ( Algeria).

Remarks. Name proposed for Melania nitida Lamarck, 1804 , sensu Philippi (1836: 157, pl. IX, fig. 17; 1844: 134), regarded as distinct species. Sometimes listed among the synonyms of Melanella polita (Linnaeus, 1758) (taxonomic discussion in Warén, 1988: 20), with an uncertain classification in Melanella. Recorded by MolluscaBase (2018) as Melanella pernula (Monterosato, 1890).

translucens, Acicularia (ex Brusina ms.) [Melanella translucens (Monterosato, 1890, ex Brusina ms.)] ( Figures 18U, V )

1890b: 160 [XXXVIIIb: 908]—available name

Type material. MCZR–M–30024 —1 sh “ E. translucens Brusina ” “Velirat!”

Type locality. Described from Mondello (Sicily), Dalmatia ( Croatia).

Remarks. A little-known species, usually ascribed to the genus Melanella Bowdich, 1822 (e.g. Sabelli et al., 1990 –1992: 34). Giannuzzi–Savelli et al. (1999: 99, figs 275a–b) published the photos of a (non type) specimen in the Monterosato collection from Trieste. Recorded by MolluscaBase (2018) as Melanella translucens (Monterosato, 1890) .
