Appolloni, Massimo, Smriglio, Carlo, Amati, Bruno, Lugliè, Lorenzo, Nofroni, Italo, Tringali, Lionello P., Mariottini, Paolo & Oliverio, Marco, 2018, Catalogue of the primary types of marine molluscan taxa described by Tommaso Allery Di Maria, Marquis of Monterosato, deposited in the Museo Civico di Zoologia, Roma, Zootaxa 4477 (1), pp. 1-138 : 27-28

fraterculus, Trochus [ Jujubinus fraterculus (Monterosato, 1880) ] ( Figures 4G, H )

1878c: 82 [XIX: 396]—nomen nudum

1880b: 220 [XXVI: 518]—available name

Type material. MCZR –M–11705 —8 sh “Monotrochus fraterculus Monts Spugne di Sfax!”// 26 sh “ M. fraterculus Monts (Zizyph.) , Boll. malac. Ital. 1880 p. 220 Spugne di Sfax ”// 2 sh “Golfo di Gabes ”// 6 sh “ Sfax ” Type locality. Described from Tunisia.

Remarks. Recorded by MolluscaBase (2018) as taxon inquirendum. We consider it as a valid species [new status] granolirata, Clanculopsis [ Clanculus jussieui ( Payraudeau, 1826) ] taxon inquirendum ( Figures 4I, J )

1889c: 30 [XXXV: 862]—available name

Type material. MCZR –M–10935 —4 sh + 5 juv. + 3 frg “ Cl. granolirata Monts. ms. Casablanca Marocco ”// 2 sh “ Clanculopsis nova sp. Casablanca Marocco ”.

Type locality. Described from Casablanca ( Morocco).

Remarks. Not recorded by MolluscaBase (2018). Monterosato compared his Clanculopsis granolirata to Monodonta glomus Philippi, 1844: 157 , that MolluscaBase (2018) also lists in the synonymy of Clanculus jussieui ( Payraudeau, 1826) . Gofas (2017) suggested that specimens from Southern Spain ( Gofas et al. 2011: 106) corresponding to Clanculus granoliratus , based on their stronger cords than C. jussieui , could represent a different species. We would keep it under C. jussieui , but as taxon inquirendum [new status].

isseli, Gibbula [ Gibbula racketti ( Payraudeau, 1826) ] taxon inquiriendum ( Figures 5A, B )

1888a: 175 [XXXIV: 837]—available name

Type material. MCZR –M–11304 —2 sh “G. ( Phorculus ) Isseli, Monts. Boll. Mal. Ital. 1889 p. 174” “Santo Stefano pr. Costantinop. (Issel as Tr. tumidus)”

Type locality. Described from Istanbul ( Turkey).

Remarks. Recorded by MolluscaBase (2018) as a synonym of Gibbula racketti ( Payraudeau, 1826) . We include with some doubts G. isseli in the synonymy of G. racketti following the currently accepted interpretation (MolluscaBase 2018). However, some peculiar features, such as the narrower umbilical chink and the monochrome whitish colour may prove diagnostic at the species level.

laeviusculus, Jujubinus (?) [ Jujubinus laeviusculus Monterosato, 1890 ] taxon inquirendum

1890a: 145 [XXXVIII a: 899]—available name

Type material. Not found

Type locality. Not indicated. Probably Palermo (Sicily) [found with G. tantilla (1890a: 145) ].

Remarks. Recorded by MolluscaBase (2018) as taxon inquirendum.
