In the year 1817, Cuvier published the first edition of his " Regne animal", and 

 revised the class of Fishes. He formed a family for the Siluri and allied fishes, to 

 which he gave the name of Siluroides. In this family, lie admitted four great genera, 

 Silurus Linn., Malapterurus Lac, Aspredo Linn., and Lorkaria Linn. The Siluri were 

 divided into five sections, the second of which was called that of the Machoirans or 

 Mystus. The latter name was erroneously quoted as of Artedi and Linnaeus in his 

 first editions (Arted. et Lin. dans ses premieres editions) ; erroneously, for the name of 

 Mystus does not occur as the designation of a genus in the special works of either of
