Adams, 1850 ) revalidated Acteon globosus Lea, 1843: 164 ( nomen nudum ) (non Bronn, 1831). Narica (?) anomala C.B. Adams, 1850: 109 ; Clench & Turn- er, 1950: 256 (pl. 39 fig. 14). Iselica anomala : Warmke & Abbott, 1961: 85 (pl. 15e); Rios, 1970: 54 , 1975: 144 (pl. 43, fig. 667), 1985: 165 (pl. 54, fig. 787), 1994: 191 (pl. 62, fig. 896), 2009: 387 (fig. 1046); Abbott, 1974: 136 (fig. 1502); Díaz & Puyana, 1994: 237 (fig. 945); Ourives et al., 2011: 335 . Phasianema (Iselica) anomalum : Altena, 1975: 7 , 77 (fig. 31). Fossarus (Iselica) anomalus : Macsotay & Campos-V., 2001: 52. Iselica globosa : Rosenberg et al., 2009:671 ; Espinosa et al., 2012: 91 ; Molluscabase, 2023. Type locality: Jamaica . Remarks: Iselica anomala has been considered a synonym of Iselica globosa , originally described as Acteon globosus by Lea in 1843. However, A. globosus is a nomen nudum, lacking a proper description and illustration, and is a secondary homonym of A. globosus (Bronn, 1831) . Consequently, A. globosus is an invalid name and cannot be employed. Therefore, the accurate course of action is to reinstate the name I. anomala , as proposed here.
