Family names, when known, given for reference.

Aptycus – Deshayes, 1845-HistNatAnim2: 228. Ammonoid operculum; variant spelling of Aptychus Meyer, 1831 . The associated names have not yet become integrated into formal taxonomy (Arkell 1957; Moore & Sylvester-Bradley 1957: L468).

annulatus, Hamites – Deshayes, 1831b: 228-229, 260, pl. 6, fig. 5. 1832-EncyMeth: 183. — Type locality: none given, probably Caen. — Type age: Jurassic. — Current status: Spiroceras annulatum (Deshayes, 1831) ( Galácz 2017: 724, figs 4D, 5X-Y) [ Spiroceratidae Hyatt, 1900 ].

theodosia, Ammonites – Deshayes, 1838a: 32, [ii], pl. 5, figs 23- 24. — Type locality: near Théodosia, Crimea Peninsula. — Type age: Cretaceous (Berriasian). — Current status: Spiticeras theodosia (Deshayes, 1838) ( Arkadiev et al. 2000: 100) [ Olcostephanidae Haug, 1910 ].

theodosia , Aptychus – Deshayes, 1838a: 31-32, [ii], pl. 6, figs 6-7. — Type locality: near Théodosia, Crimea Peninsula. — Type age: not stated. Ammonoid operculum (see above under genus). — Current status: Tauriaptychus theodosia (Deshayes, 1838) ( Kozlova & Arkadiev 2003: 40; 377) .

lyelli, Ammonites – Leymerie, 1841: 320, 322, nomen nudum; Leymerie, in d’Orbigny (1841: 255-257, pl. 74; 1842: 15, 32, pl. 17, fig. 16a-b, ex Deshayes ms). — Type localities: Courcellessur-Voire, Ervy-le-Châtel & Maurepaire. — Type age: early Cretaceous (Albian). — Current status: Lyelliceras lyelli (Leymerie, in d’Orbigny, 1841) ( Arkell et al. 1957: L409-411) [ Lyelliceratidae Spath, 1921 ].

Subclass NAUTILOIDEA Agassiz, 1847

Campulites – Deshayes, 1845-HistNatAnim2: 253 [p. misnumbered as “53”]-254, without named species. This name had been listed as a vernacular (“Campulite”) in Deshayes, 1830a-EncyMeth: 226; 1832-EncyMeth: 606, 670. While it has been placed, with question, into synonymies ( Teichert 1940: 594), unrelated groups were originally encompassed and this should remain a nomen dubium (R. T. Becker, pers. comm., November 15, 2022).
