The shell morphology of the almost extinct family Eocypraeidae is compared with that of the Ovulidae and Cypraeidae. Up to now the DNA as well as RNA of the Eocypraeidae was never examined. The validity of the subfamily Prionovolvinae FEHSE, 2007 within the Ovulidae is confirmed. The Eocypraeidae represents an independent family within the Cypraeoi...

... Prionovolva. Gehäuse von Prionovolva weisen als eine der wenigen Ovulidae Labralzähne (5) ähnlich der Cypraeidae auf, jedoch haben diese nicht im Entferntesten Ähnlichkeit mit dem Gehäuse von Grovesia. Auch gibt es keine Ähnlichkeit bzgl. des Anal-und Siphonalkanals. Die einzige Ähnlichkeit findet sich im Gehäuseumriss. DOLIN & LEDON (2002: 333, Fig. 1) zeigten nur Zeichnungen von Prionovolva, die in einigen wesentlichen Punkten (Funiculum, Terminalfalte, Kanäle) ungenau sind und eine Ähnlichkeit implizieren ...Context 2
... (4) on Prionovolva. Shells of Prionovolva are one of the few Ovulidae to have labral denticles (5) similar to the Cypraeidae, but they are not remotely similar to the shell of Grovesia. There is also no similarity with regard to the anal and siphon channels. The only similarity can be found in the outline of the shell. DOLIN & LEDON (2002: 333, Fig. 1) only showed outlines of Prionovolva, which are imprecise in some essential points (funiculum, terminal folds, canals) and should imply similarity to Grovesia. DOLIN & DOCKERY (2018: 46) schrieben: "We include in this taxon [… Subfamily: Eocypraeinae Schilder, 1924 …] whole clade D Schiaparelli et al. (2005), even if it is obviously ...Context 3
... Cypraeoidea. In the SCHILDER's catalog (1971), 'generic origins' are also described, which have largely been confirmed by genetics (e.g. LORENZ, 2017). SCHILDER (1939: Plate 7) had derived first the origin of the Ovulidae via Palaeocypraea F.A. SCHILDER 1928 andEocypraea COSSMANN 1903, but he never knew the differences in the protoconches (see Fig. 1). Otherwise he would have drawn different conclusions. He (SCHILDER & SCHILDER, 1971) also placed the Pediculariidae as a subfamily of the Ovulidae, but this is impossible because of the tripartite Osphradium of the Ovulidae (as well as the Cypraeidae) (SIMONE, 2011 Table 2) and even just a synonym of Transovula DE GREGORIO 1880. ...Context 4
... of recent Cypraeidae within a genus, this question arises all the more. The assignment of species to the genera of recent Cypraeidae is now also secured by means of DNA or RNA. An impressive picture of the variability of the shell morphology within the genera and the intraspecific variability can be obtained by studying the following genera Fig. 1-5) im späten Eozän. Obwohl das convolute Gehäuse (PACAUD, 2018A: Text Figure 2) klar erkennbar ist, wurde Borystheniella zu den Cypraeidae gestellt (PACAUD, 2018A: 17; vgl. Kapitel ...Context 5

The later interpretations (MNHN.F.J01934; COSSMANN & PISSARRO, 1913: pl. 32, fig. 160-1) only represent a Transovula sp. This shell can by no means be used as a neotype for O. delphinoides! Taking into account the original type shell and the "plesiotype" (COSSMANN, 1903: pl. 9, fig. 21) it becomes obvious that the newly introduced genus Borystheniella PACAUD 2018A -type species Borystheniella incisa PACAUD, 2018A -is only ...Context 6

Résumé : Une recherche dans les collections du MNHN nous ont fait découvrir, dans les bacs de la collection Alexandre Brongniart, le matériel type de 3 taxons appartenant aux Cypraeoidea qui
provenaient du Cabinet d’Histoire naturelle de Barthélemy Faujas de Saint-Fond et qui ont été décrits par Lamarck en 1810. Nous redonnons ici des illustrations...
