Griffin & Nielsen (2008):
TYPE MATERIAL. Eight syntypes are housed in the Typothèque of the Laboratoire de Géologie, including one specimen from Cucao, Chiloé, under number MNHN-Gg2002/50 (height 26.4 mm) and seven specimens from Topocalma under number MNHN-Gg2002/77 (largest specimen height 32 mm).
REMARKS. Having the typical callus depression, this species clearly belongs in Glossaulax Pilsbry, 1929. Several nominal species from Chile might fall in synonymy with Natica pachystoma. However, it is not yet clear wheather it is one highly variable species (like the type species of Glossaulax, i.e., Natica reclusiana Deshayes, 1839) or a species complex. |
