Siphonaria coreensis A. Adams & Reeve 1850

Siphonaria coreensis A. Adams & Reeve, 1850 Siphonaria coreensis A. Adams & Reeve 1850: 69, pl. 13, fig. 1a, b (type locality: ‘Corean Archipelago’ [Korean Archipelago]).—H. Adams & A. Adams 1855 (in 1853–58): 271; Hanley 1858b: 151, A. Adams 1863: 271; Paetel 1873: 117, 1883: 178, 1889: 428; Pilsbry 1895: 5, 161; Kuroda & Habe 1952: 86; Cernohorsky 1972: 210; Galindo 1977: 416; White & Dayrat 2012: 62. 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.
