REMARKS

Not treated by Deshayes (1851). A label associated with the specimens is a typical black-bordered label of the Férussac collection and states that they were received from “Gaudicho” (i.e. Gaudichaud); it therefore confirms that they were obtained during the Freycinet expedition. The labels to which the three specimens were once glued says “type” and “ Coll. Férussac 1837”. All three shells closely match Férussac’s illustrations, although one retains a significant amount of periostracum that is not shown in the illustrations. However, the other two are damaged, probably in the course of removing them from the label, so the undamaged specimen, with periostracum, is here selected as the lectotype ( MNHN IM-2000-30843) ; the remaining specimens in the original lot are paralectotypes ( MNHN IM-2000-30844) .
