REMARKS

The original description was explicitly based on specimens in the collections of both Pease and Crosse, as well as noting that the shells were variously coloured (“d’un jaune paille, rougeâtre clair ou brunâtre”). Fischer-Piette (1950: 73, pl. 4, fig. 53) noted and illustrated a measured “Exemplaire-type”, thereby designating a lectotype, though not mentioning other specimens (see introductory text regarding lectotypes). A label associated with the specimen indicates that it was received from Pease in 1868. Johnson (1994: 26) referenced Fischer-Piette’s statement but credited him with having listed the “ Holotype ”, while also noting additional “ paratypes ”, i.e. paralectotypes (MCZ 23338).
