Remarks.

In the old literature the name appears frequently as " Melanopsis bonellii Sismonda". The name is not available from Sismonda (1847: 55), however, who solely referred to a misidentified name ( Melanopsis carinata non Sowerby) in the unpublished museum catalogue of Bonelli (1827) but did not supply a description. It appears as a nomen nudum also in d’Orbigny (1852: 28) and Doderlein (1863: 16). Hörnes (1856: 595) mentioned the name along with two other melanopsids from Italy and gave a collective description for all of them (translated from German: "all individuals are smaller as the Viennese [ Melanopsis martiniana ], as well as more elongate, but they have the characteristic marginal bulge and the typical keel below the suture"). Following Art. 12.1, every name [...] must be accompanied by a description or a definition of the taxon that it denotes [...], which is not the case for the mentioning of Melanopsis bonellii in Hörnes (1856) because the description given there refers to a group of taxa and not a single taxon. Manzoni (1870) made the name available by providing an illustration (Art. 12.2.7).

The name " bonelli " as mentioned in Sacco (1889: 65) and Syrides (1998: 173) is an incorrect subsequent spelling.
