Calliostoma nudum (Philippi, 1845) Fig. 5A

Material examined.

1 spm (13 × 12 mm).

Synonymy.

See Morris and Rosenberg (2005).

Remarks.

Castellanos and Landoni (1989) commented that this species is a complex variable in which the species Calliostoma kophameli Strebel, 1905, Calliostoma venustulum (Strebel, 1908), and Calliostoma falklandicum (Strebel, 1908) appear to be simply different morphotypes of the species Calliostoma nudum . Accordingly, a morphological study is required that details the various examples of the species.
