Genus

Cryptosaurus eumerus (Seeley, 1869) = Cryptodraco (Lydekker, 1889)

To replace supposedly preoccupied Cryptosaurus Seeley,1869. Lydekker\\\'s citation of [\\\"Cryptosaurus geoffroy\\\"] is based on a typographical error for [Cystosaurus geoffroy] 1833 in a German journal, an error repeated by Agassiz in his 1846 Nomenclator Zoologicus. Such incorrect subsequent spellings are not a basis for homonymy under ICZN rules. Cryptosaurus eumerus = Cryptodraco Lydekker\\\'s renaming of Cryptosaurus to Cryptodraco was unjustified.
