038E81139354260AFE3CFAEFFBEFFB86.taxon	discussion	Remarks. Olivella floralia was originally illustrated by Duclos (1835) as Oliva oryza. This name, however, was already pre-occupied by a species previously described by Lamarck (1822, p. 439). Duclos (1844) corrected the mistake, changing the species name to Oliva floralia. Nevertheless, the change was not used in the subtitles of the illustration plate attributed by the author to the description of O. floralia, where it reads ‘ Oliva oryza ’.	en	Antunes, Luís Vítor Oliveira, Figueira, Raquel, Dilnei de Castro Oliveira, Cléo (2022): Anatomy of the pallial cavity and associated organs in three species of Olivella (Mollusca: Neogastropoda: Olividae) from Brazil.
