REMARKS

The original description was explicitly based on specimens in the collections of both Pease and Crosse. Cooke (in Hyatt & Pilsbry 1910 [in 1910-1911]: 50, 51, pl. 8, figs 47, 48) mentioned “specimens (probably the types)[…] belonging to Pease’s own collection, which is now at the Museum of Comparative Zoology”, and illustrated one of his own specimens. Fischer- Piette (1950: 73, pl. 4, fig. 52) noted Cooke’s illustrated specimen and illustrated his own measured “Exemplairetype”, which is here treated as a valid lectotype designation (see introductory text regarding lectotypes). A label of the collection of the Journal de Conchyliologie, associated with the specimen and written at the time of Fischer-Piette, says “type”, and another label indicates that it is that illustrated by Fischer-Piette (1950: pl. 4, fig. 52), which indeed it is. Johnson (1994: 198) referenced Fischer-Piette’s statement but credited him with having listed the “Measured holotype ”, and noted additional “ paratypes ” ( MCZ 45181 View Materials ).
