Pale specimens, without the conspicuous longitudinal zigzag markings on the shell, from off SW Taiwan have been named Oliva mustelina f. lanberti Bert, 1984. As this form name was introduced after 1961, it has no standing under the ICZN code. Such specimens were named Oliva mustelina inornata Marrat, 1870, by Petuch & Sargent (1986: 104, Pl. 16 figs. 19-20). Oliva inornata Marrat, 1871, however, seems to involve a different taxon.
