Amphiuma tridactylum Cuvier, 1827

Holbrook (1842e:93, pl. 31) gave a brief account of the Three-toed Amphiuma, which he implied never having seen, perhaps other than a specimen in the ANSP collected by “ Dr. Pitcher. ” Holbrook suggested that this specimen was collected in the “Neorho” (Neosho) River, near Fort Gibson, Oklahoma, though this is significantly outside of the known extent of the modern-day range of the species (Petranka 2010; Powell et al. 2016). Holbrook’s description is a quoted translation of Cuvier, and the crude illustration by J. Queen seems to have been copied from that of Cuvier (1827: figs. 4–6), which may be the lectotype MNHN-RA 0.7821 or one of the other paralectotypes (see Thireau 1986).
