cionella, Eulima [ Vitreolina cionella (Monterosato, 1878) ] ( Figures 18E, F )

1878a: 154 [XIX: 444]—available name

Type material. MCZR–M–23901 —2 sh “ E. cionella Monts, Mondello, Marzo ‘76”

Type locality. Described from Palermo (Sicily).

Remarks. An elusive eulimid described with few words, as usual. The size pointed out in the description (height: 3 mm) is obviously excessive for this tiny shell, being possibly a miswriting for “ 1.3 mm ”. Gaglini (1992b) offered light photographs of a syntype and of its original label from the Monterosato collection, and assigned the species to the genus Vitreolina Monterosato, 1884 . Despite it being quite a characteristic species, it has been recorded only occasionally (e.g. Gaglini, 1992b; Tringali, 1996; Gofas et al. 2011). Recorded by MolluscaBase (2018) as Vitreolina cionella (Monterosato, 1878) .

curva, Eulima [ Vitreolina curva (Monterosato, 1874 ex Jeffreys ms.)] ( Figures 18G, H )

1874 a: 269 [X: 195]—available name

Type material. MCZR–M–23626 —3 sh “ Eulima curva Jeffr. Trapani ” handwriting by Brugnone // “ Eulima curva Jeffr. Monts. in Jour. Conchyl. 1874 varie località”

Type locality. Described from Palermo , Trapani , and Milazzo † (Sicily), and Adriatic Sea ( Italy).

Remarks. Introduced with a concise description, yet effective to outline the characteristic shell shape. A full valid species belonging to the genus Vitreolina Monterosato, 1884 . Recorded by MolluscaBase (2018) as Vitreolina curva (Monterosato, 1874) .
