Taxonomic Remarks
Sherborn & Griffin (1934) have noticed that the plates with the figure of the holotype of the nominal Carapus inaequilabiatus (i.e., the original description of that species) was actually published in 1839, while the text description was published some years later, in 1847. In the text description, the generic name appears as Carapeus (a misspelling; 1847:11). The type locality of Gymnotus inaequilabiatus has been sometimes cited elsewhere as "rio de La Plata" (e.g., Mago-Leccia, 1994:55).
