REMARKS

The original description was explicitly based on more than one specimen: “habituellement sénestre, rarement dextre”; “Coloration générale blanchâtre, ou d’un jaune de paille clair”; and “quelques exemplaires”. However, Fischer-Piette (1950: 71, pl. 14, fig. 8) listed and figured a single specimen as the “ Holotype ”. Johnson (1994: 12) referred to Fischer- Piette (1950: 71) as having identified the “ Holotype ” but also noted “ paratypes ” (MCZ 45155). Neither listing constitutes a lectotype designation (see introductory text regarding lectotypes). The illustrations of Pease are not detailed but both Pease and Fischer-Piette gave the shell’s size as 6 mm, which is very close to the actual dimension of the specimen in MNHN IM-2000-30807. A label of the collection of the Journal de Conchyliologie, associated with this specimen and written at the time of Fischer-Piette, says “ Holotype ”, and this and two other labels state that it is the specimen figured. It is therefore here designated as the lectotype.
