DESCRIPTION

Spire whorls are high, very convex and separated by deep sutures.Last whorl is very high, globular, slightly elongate in the base, measuring more than ¾ of the shell height. The teleoconch lacks a prominent umbilicus and shows an enrolled columellar lip. The rate of the width to the height (LT/HT) is approximately 0.75, apex angle is between 90-95 and LT (width)/D1 (diameter) of shell is 1.04-1.1 (Appendix 1).

REMARKS

The studied specimen resembles both “ Ampullina ” vapincana and “ Ampullina ” vulcani ( Brongniart, 1823) , the two being considered possible conspecific ( Piccoli & Mocellin 1962; Brigantini 1985). Based on comparison with type material from the d’Orbigny and Brongniart collections of the Muséum national d’Histoire naturelle, Paris (MNHN, Dépar- tement Histoire de la Terre) (B24241-4: Faudon, Hautes Alpes, France; B22105: Roncà, Italy), “ A. ” vapincana is considered distinct by its more convex and higher spire whorls. The specimen, as expressed by parameters shown in Appendix 1, is thus assigned to the d’Orbigny species.
