TL-2 states that this publication is 'Reprinted from Mém. Soc. Hist. Nat. Paris 1(1): [210]-232, pl. 11-12. 1823'. However the BHL copy of Mém. Soc. Hist. Nat. Paris has a cover page from the part containing Mém. Nouv. Gen. Guttif., suggesting the part was published in 1824. Mém. Nouv. Gen. Guttif. therefore appears to be a preprint not a reprint.
