The purpose of this application, under Article 75.6 of the Code, is to conserve the current usage of the name Cerithiopsis tubercularis (Montagu, 1803) for a species of cerithiopsine gastropod from the southern coast of Great Britain. The lectotype of Cerithiopsis tubercularis (Montagu, 1803) is not in taxonomic accord with the current usage of this name and the confusing description ignoring the part bearing the most obvious diagnostic characters led to considerable confusion. It is proposed that the previous type fixations for the species Cerithiopsis tubercularis (Montagu, 1803) be set aside and a neotype consistent with the current usage be designated.
