Histoire Naturelle Complète des Reptiles'
by AMC Duméril & G Bibron, 1854.
The multi-volume series, 'Erpétologie Générale, ou, Histoire Naturelle Complète des Reptiles', was released over a twenty year period beginning in 1834. The final volume is an atlas with more than one hundred steel engravings that were (I presume) hand-coloured.
'Erpétologie Générale' is owned by the Smithsonian Institution and is made available online through the Biodiversity Heritage Library and the Internet Archive (the plates featured above were downloaded from the latter source).
