REMARKS

The original description was explicitly based on specimens in the collections of both Pease and Crosse. A “cotype” in ANSP was illustrated by Cooke (in Hyatt & Pilsbry 1910 [in 1910- 1911]: 19, pl. 8, figs 63, 64). Fischer-Piette (1950: 72) noted an “Exemplaire-type (8.2 mm)” and a “ paratype de 7 mm ” (nowMNHN IM-2000-30822 and MNHN IM-2000-30823, respectively), and in reference to the ANSP “ paratype ” already illustrated (by Cooke) stated that it would not be useful to illustrate “le type” (i.e. the “exemplaire-type”). This constitutes a valid lectotype designation (see introductory text regarding lectotypes). A label of the collection of the Journal de Conchyliologie and written at the time of Fischer-Piette says “type + paratype ”, and an earlier label says “type”. There were two intact specimens in the original MNHN lot (i.e. lectotype and paralectotype), but also a broken specimen that was not mentioned by Fischer-Piette ; this specimen is also considered a paralectotype. Johnson (1994: 11) selected the ANSP specimen ( ANSP 57806 View Materials ) as lectotype, noting the MNHN specimens as paralectotypes ; this designation is not valid as it is here considered that the earlier designation of Fischer-Piette was valid.
