Locality. Trindade Island , site Lixo Bay, Sample M17022 N.

Material. 4 RV, 2 LV, and 3 C (dead assemblage).

Remarks. The species Auradilus convolutus , described by Brady (1868) for Mauritius, has long been absent in the literature. It was only with Hu’s (1979) work that it reappeared in the scientific literature, but it has received different names ever since. Although Brady (1868) designed only one LV in lateral view, it showed enough detail that, along with the description, the species could be identified relatively easily, as pointed out by Mostafawi et al. (2005). In this paper, we present a new and more complete list of synonyms, presenting some differences from that of Mostafawi et al. (2005, p. 132). Moreover, it is noteworthy that Radimella minor described by Hu (1979, p.1, fig. 10) does not appear to be specific to Auradilus convolutus , as proposed by these authors. It is smaller than A. convolutus and differs in ornamentation in adults and juveniles.

Stratigraphic range. Pleistocene to Holocene.

Occurrence and distribution. In the study area, the species occurs in Trindade Island in the following localities: Lixo Bay, Racha Island, Crista do Galo Pool, Cabritos Beach, and Andradas Beach. It occurs also in other Brazilian territorial waters (Northern, Northeastern and Eastern shelves, Sepetiba Bay, and littoral of Santa Catarina State), the Indian Ocean, and the Western Pacific. In the fossil record, it occurs in the Pleistocene of Taiwan. See references in the synonymy list.
