Skeneoides jeffreysii


jeffreysii , Helonyx [ Cadulus jeffreysi (Monterosato, 1875) ] ( Figures 40P, Q View FIGURE 40 )

1875b: 20 [XIII: 246]—available name

Type material. MCZR–M–12918 —8 sh “Sciacca”// 2 sh “St. Helena”// 4 sh “Hel. jeffresii sped. Francese mediterraneo”. Label on the box bottom: “ H. jeffreysii Monts = Cadulus subfusiformis Jeffr. (non M. Sars) vedi Jeffr. Brit. Conch. V. tav. VIII, f. 6. e tav. CI fig. 3”.

MCZR –M–12896 —154 sh “Helonix jeffresi, Monterosato = Cadulus subfusiformis Jeffr. Palermo , England ”// 6 sh “Helonix jeffreysi, Monterosato England ”

Type locality. Described from Palermo and San Vito lo Capo (Sicily), Napoli ( Italy), Mediterranean Sea and Atlantic.

Remarks. The name was introduced (with a description) for Cadulus subfusiformis (M. Sars, 1865) , sensu Jeffreys (1869 [1862–1869]: 196). Monterosato (1875a: 20) stated that the species inhabits both the Atlantic and the Mediterranean waters, and recorded it from Palermo, Capo San Vito, Napoli and the Aegean Sea. The species was discussed in Gaglini (1985), who figured (p. 7, fig. 1) two shells in the MCZR from the English coasts: we failed to locate those shells, which could be regarded as syntypes. Recorded by MolluscaBase (2018) as Cadulus jeffreysi (Monterosato, 1875) .

ovulinum, Cadulus [ Cadulus ovulinum Monterosato, 1891 ] taxon inquirendum ( Figures 40R, S View FIGURE 40 )

1891c: 15 [XL: 948]—available name

Type material. MCZR–M–30050 —1 sh “ C. ovulinum, Monts in Bull. Soc. Sc. Mat. Pal. 1891 ) Foss. Ficarazzi! Diverso dal C. ovulum foss. di Messina”

Type locality. Described from Ficarazzi † (Sicily).

Remarks. The name was introduced with a brief description. It would be similar to C. ovulum ( Philippi, 1844) , but smaller and less swollen. The “F” after the description pointed out that the species was found at Ficarazzi (Palermo). Recorded by MolluscaBase (2018) as taxon inquirendum.
