Species Sigaretus subglobosus Sowerby 1846


Discussion / Comments:
Griffin & Nielsen (2008):
TYPE MATERIAL. Two syntypes of Sigaretus subglobosus: NHM-G26350-1 (Navidad); holotype of Sigaretus elegans housed in the Typothèque of the Laboratoire de Géologie under number MNHN-Gg2002/79 (Topocalma). REMARKS. Sinum subglobosum is well represented in collections from the Navidad Formation, central Chile, to Isla Stokes, southern Chile. It can be easily distinguished from the cooccurring S. pullum (Philippi, 1887), which is smaller, basally flattened and has an oblique aperture. Sinum subglobosum is an unusually tall, subspherical, thick-shelled species of Sinum, and possibly belongs in another genus.
