As indicated in the title of the "Genera Piscium" (v. 3), Artedi admitted into the 

 system 242 nominal species under 52 genera, but in this number are included the 

 Cetaceans, which were regarded as constituting an order of fishes named Plagiuri : 

 these being eliminated (14 species representing 7 genera), the number is reduced to 

 228 species and 45 genera, to these, however, may be added 13 other genera indi- 

 cated by him, 5 in the supplement to the "Genera Piscium," and 8 in the 

 " Synonymia Piscium." 



Artedi may be justly regarded as the father of modern Ichthyology, having intro- 

 duced a precise terminology, full and pertinent diagnoses, and throughout uninominal 

 generic names. He first introduced consideration of the number of brauchiostegal 

 rays for distinctions of genera, etc. He distributed the true fishes into the orders 

 Malacopterygii (=Malacopterygii Cuv.-f-Syngnathus, Stromateus, Anarrhicas), Acan- 

 thopterygii (=Acanthopterygii Cuv.), founded on the real or supposed structure of the 

 fins, Branchiostegii (a heterogeneous group based "on erroneous ideas), and Chondrop- 

 terygii (=Chondropterygii Cuv.) 



The edition of the Genera Piscium published by Walbaum (1792) will be noticed 

 under the name of the editor who made the work the vehicle of a new compilation 

 of specific descriptions. 



1740-1749.
