Hydra, lizard, and birds, illustration from Seba's Locupletissimi rerum naturalium thesauri accurata descriptio
This image showing what appears to be two lizard species is a composite plate from Prince Maximilian zu Wied's Abbildungen zur Naturgeschichte Brasiliens discussed by AMNH curator emeritus of the AMNH Herpetology Department in the Division of Vertebrate Zoology, Charles W. Myers. What Wied believed were two distinct lizards, were actually, Myers writes, male and female of the same species.
