Griffin & Nielsen (2008): TYPE MATERIAL. Three syntypes: NHM-G26337, NHM-G26338 (smallest syntype, Sowerby’s pl. 4, fig. 64), NHM-G26365 (all Isla Guafo). According to A.G. Beu (personal communication) NHM-G26338 is a juvenile Fusitriton, not identifiable to species. To fix the status of this species we select NHM-G26337, a typical Sassia leucostomoides, as the lectotype. REMARKS. Frassinetti (2000) cited quite a large suite of specimens present in the Museo Nacional de Historia Natural, Santiago, Chile, from the type locality. However, the matrix in the syntypes is hard sandstone, while Frassinetti’s specimens come from mudstone. One syntype (NHM-G26338) has a large protoconch of about 4.2 slightly eroded whorls that show traces of spiral threads, diameter and height of protoconch is 2.6 mm each. Frassinetti’s (2000) specimens have protoconchs of about 3.5 to 4 whorls, which seems to reflect intraspecific variation. |
