REMARKS

Considered by Pease as a species of “ Hélictères ” (i.e. genus Helicteres , though the formal genus name was not used and it is therefore placed in square brackets above) in the subgenus Leptachatina (see introductory text regarding species of Pease). The original description was not explicitly based on only a single specimen but neither does it imply the existence of syntypes. The species was illustrated by Crosse (1876: 97, pl. 4, fig. 6), who indicated that there were two “individus typiques” in the collection of the Journal de Conchyliologie. Fischer-Piette (1950: 149) noted the specimen illustrated by Crosse and listed a measured “ Holotype ” (not explicitly the specimen illustrated by Crosse). Johnson (1994: 16) simply referenced Fischer-Piette’s statement, while also noting additional “ paratypes ” ( MCZ 45173 View Materials ). Neither of these listings constitutes a lectotype designation (see introductory text regarding lectotypes). Despite Crosse’s statement that there were two specimens in the collection, there is now only one specimen in the MNHN lot. A label of the collection of the Journal de Conchyliologie, associated with the specimen and written at the time of Fischer-Piette, says “ Holotype ”, and this and two other labels indicate that the specimen is that illustrated by Crosse (1876: pl. 4, fig. 6), one indicating that it was received from Pease in 1869. Although the figures are not detailed, and the shell is rather featureless, the shell in MNHN IM-2000-30828 is here designated as the lectotype.
