Abstract
Figures are published for the first time of Simpulum papillosum A. Adams, 1870 (= Bufonariella ranelloides (Reeve)) and Triton obscurus A. Adams, 1854 (= Septa (Cabeslanimorpha) tabulata durbanensis (E. A. Smith), non Triton obscurus Reeve, 1844). Triton toebbeckel Lischke, 1870, usually regarded as the earliest name for the Japanese subspecies of Septa (Cabestanimorpha) tabulaia, is a synonym of Tritoniscus labiosus (Wood, 1828). The earliest name for the Japanese form of S. tabulata is Lotorium kilensis G. B. Sowerby III, 1915; type specimens of L. kilensis are figured. Triton imbricata W. H. D. Adams, 1868, published in “The Mysteries of the Ocean”, is a synonym of Charonia tritonis tritonis. The date of publication of Cryotritonium von Martens is discussed: Fusitriton Cossmann is the valid name for the genus. The name Gyrineum (Biplex) jacundum (A. Adams, 1853) is used instead of the preoccupied Biplex pulchelia (Forbes) , and a neotype is designated for Ranella jacunda A. Adams.
