Designation of a lectotype for Crocodilus siamensis Schneider, 1801 (Reptilian: Crocodylia)

Schneider (1801) named Crocodilus siamensis on the basis of three specimens from Siam that were described and figured (but not named) in an earlier publication (Anon, 1688). None of the three specimens are known to have been preserved. Cuvier (1807) considered the syntypical series composite and proposed the replacement name Crocodilus galeatus for one of the included species. Cuvier's (1807) replacement name is assessed and rejected as unjustified. In the interest of nomenclatural stability, a lectotype of C. siamensis Schneider is designated. The type locality of C. siamensis is shown to be Louvo, Siam (= Ayutthaya, Thailand).Original Abstract: Schneider (1801) a cree l'espece nominale Crocodilus siamensis a partir de trios specimens du Siam decrits et figures (sans etre nommes) dans un travail publie anterieurement (Anon., 1688). Aucun de ces specimens n'a ete conserve. Cuvier (1807) a considere que la serie-type de Crocodilus siamensis etait composite, et a propose en consequence un nom de remplacement, Crocodilus galeatus. La validite de ce nom de remplacement est evaluee, et il est rejete car etant injustifie. Dans l'interet de la stabilite de la nomenclature, un lectotype de C. siamensis Schneider est designe. La localite-type de C. siamensis est done fixee a Louvo, Siam (= Ayutthaya, Thailande).
