Omphaloptycha escheri var. fusus ( Stoppani, 1858)
Specimen: MSNM i12950 - Fig. 1a
Height: 30 mm (= last 2 whorls).
Stoppani Label: Chemnitzia retrozonata Stopp. pl. 6, fig. 7. 1228 Esino.
Anonymous Label: not present.
Garassino Label: Omphaloptycha escheri, Olotipo. Esino. Triassico Superiore.
Specimen described by Stoppani: Chemnitzia retrozonata Stoppani, 1858 -60, pag. 23, pl. 6, fig. 7. Estimated Height (Stoppani): 35 mm. Pleural Angle: 40°.
Height (from Kittl 1899, pag. 122; fig. 49): 27 mm (last 2 whorls), but the drawing was probably enlarged slightly.
Discussion: MSNM i12950 is 30 mm high and 20 mm wide. It is composed of the last two whorls. The size of the specimen is larger than that described by Stoppani. Moreover, the shapes of the whorls and peristome are more similar to those of Chemnitzia fusus . However, the number written on the specimen corresponds with that on Stoppani’s original label.
Conclusion: Specimen MSNM i12950 is not the specimen described by Stoppani of Chemnitzia retrozonata .
