REMARKS
This species was described 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
.
Crosse (1876
: pl. 3, fig. 6) illustrated a single specimen, presumably one of the two “exemplaires typiques” [typical examples] in the collection of the
Journal de Conchyliologie
(
Crosse 1876: 98
). Fischer-Piette (1950: 149) listed the specimen illustrated by Crosse as an “Exemplaire figuré”, also not treating it explicitly as a type.
Johnson (1994: 26)
referenced Fischer-Piette’s statement but credited him with having listed the “
Holotype
”; he did not mention additional type specimens. Johnson’s treatment did not constitute a
lectotype
fixation (see introductory text regarding
lectotypes
). Despite Crosse’s statement that there were
two specimens
in the collection, there is now only
one specimen
in this lot. The labels associated with this specimen indicate that it is the specimen illustrated by
Crosse (1876
: pl. 3, fig. 6) and that it was received from Pease in 1869; and although the figures are not detailed and the shell is rather featureless and broken into two fragments, it is nonetheless here designated as the
lectotype
.
