In Vol. XVIII, pag. 135, of this periodical I have described a new Melania with the specific name Junghuhni. Now some time ago Prof. K. Martin directed my attention to the fact, that this name was preoccupied for a fossil species, described in 1879/80 in his work: Die Tertiärschichten auf Java; Palaeontologischer Theil, pag. 89, pl. XIV, fig. 20. So his name has the priority, and my species must receive another name, for which I propose Melania Martini, after the person who has detected the error. I may make the apology, that, as it is already not an easy matter to avoid such errors with the names of recent species, it becomes very difficult, to know also the names of the numerous fossils.
