During the course of our research on the paleobiology and systematics ofmammalian remains of the Santa Cruz Formation of Argentine Patagonia,we became awareof differences in the early literature dealing with Santacrucian (late Early Miocene)mammals. Although literature errors are not uncommon, they are often only aninconvenience. However, in this case it involves an article in which numeroustaxa were erected, so that particular attention must be paid to thecircumstances of its publication. The article in question is Florentino Ameghino?s(1894a, b) Énumération synoptique des espèces de mammifères fossiles desformations éocènes de Patagonie (henceforth, Énumération). This article waspublished formally in 1893 in the Boletín de la Academia Nacional deCiencias en Córdoba (henceforth, Boletín) and also in 1894, withidentical title and text but different pagination, as an offprint (henceforth, offprint).For these reasons the existence of two versions with differing paginations and date,albeit with identical text, clearly has implications in the recognition offormal taxonomic names; and so the question arises as to which of the twoversions should be formally recognized for such purposes.
