REMARKS

The original description was explicitly based on specimens in the collections of both Pease and Crosse, and noted multiple “individus” and “suture quelquefois [sometimes] étroitement bordée”. Cooke (in Hyatt & Pilsbry 1910 [in 1910-1911]: 38, pl. 1, figs. 8, 9) noted two specimens presented by Pease to ANSP and illustrated one of them (ANSP 57821) but did not mention the type status of either. Fischer-Piette (1950: 73) noted an “Exemplaire-type” and a “ paratype ” (said to measure 7.5 and 7.0 mm, respectively, both values slightly greater than the actual sizes of 7.3 and 6.6 mm), thereby designating a lectotype (see introductory text regarding lectotypes), though without illustrating it. The two specimens are now MNHN IM-2000-30834 and MNHN IM-2000-30835, respectively. Johnson (1994: 24) referenced Fischer-Piette’s statement but credited him with having listed the “ Holotype ”; he also listed the above ANSP specimen as a “ paratype ”, and mentioned additional paratypes (MCZ 45176).
