Taxonomic remarks. The original description, original figures and type locality provide the only indication to the identity of S. coreensis . No types of S. coreensis could be located at the UKNHM (J. Ablett, pers. comm.). The identity of the species cannot be clarified based on the original description and figures alone and remains indeterminable. The identity of this species may be resolved in the future when suitable topographic material should become available. The original figures are not of S. sirius (Figs36E, F), which differs in shell morphology (i.e., multiple ribs on siphonal ridge) nor of S. japonica (Figs 7A–E), which differs in shell geometry. Subsequently, Reeve (1856) listed S. coreensis as a synonym of S. atra . However, Reeve’s description and figure are based on a misidentification and herein attributed to S. sirius (Figs 36E 0F). Lischke (1871: 105) and Cernohorsky (1972: 210) followed Reeve’s treatment as a synonym of S. atra .
