Nacella deaurata (Gmelin, 1791) Fig. 4A-B

Material examined.

66 spm (17 × 12 × 8 - 21 × 17 × 11 mm).

Synonymy.

See Valdovinos and Rüth (2005).

Remarks.

According to the classification done by Valdovinos and Rüth (2005), the shell morphology of Nacella deaurata is similar to the species Nacella delicatissima . Later, Arazamendi et al. (2009), based on molecular techniques, concluded that the specimens of Nacella delicatissima are combined with the specimens of Nacella magellanica and Nacella deaurata , suggesting that Nacella delicatissima is a morphotype of both species.
