Dr. Johann Baptist Ritter von Spix collected Mollusca in South America from 1817 to 1820. After his return to Europe he completed the plates, including their legends, and brief diagnoses for a monograph on the taxa he had collected, but died in 1826 before the main text was written. Dr. Johann Andreas Wagner was enlisted to complete the monograph, which he did, and it was published in 1827. In total, 64 gastropod and 20 bivalve taxa were illustrated. In developing the monograph for publication, Wagner altered Spix s concepts of many of the taxa, in some cases using his own name, not Spix s, as the author of the name. We discuss Wagne s rationale for making these changes. We discuss the appropriate citation of the authorship of the work, concluding that it should be cited as of Wagner alone. We also discuss the appropriate authorship of the species, concluding that in all cases in which Spix had provided a name on the plates authorship should be given as Spix in Wagner . Wagner also created some new names, three of which are replacements for Spix s names, which are preoccupied, but the remaining ones are unnecessary replacement names for Spix s names (of which they are therefore junior objective synonyms). Spix s type material is in the Zoologische Staatssammlung in Munich, although some of it is missing as a result of damage sustained during World War II. 17 pp., 4 figs, 4.…
