The typeset name on the plate was Mugil corsula, corrected by errata bound with plates of CAS copy as, "Plate I. for Mugil corsula read Pimelodus; the Mugil corsula being delineated Plate IX. fig. 97." It could be argued that Hamilton just identified the figure to genus, in which case the specific name is not available; Hamilton did not describe a Pimelodus with the name corsula in the text (1822) [but P. menoda (p. 203, 279) might be the corresponding species]. If Pimelodus corsula is not regarded as available from Hamilton 1822, Pl. 1, then the name dates Valenciennes 1840 as Bagrus corsula (see Ng & Ferraris 2000:130 [ref. 25041], Ferraris 2007:89 [ref. 29155]).
