Bott would have almost certainly have borrowed the largest male from MNHN and drawn its G1, and his figures of this structure are presumably from this specimen. From his text, Bott had borrowed only four males and a juvenile female from MNHN for his revision, not the complete series. There is no evidence he examined the USNM material.
