ARTEDI S SYSTE3I,

once proceed to the enumeiation of those which have 

 been the most celebrated ; but the curious reader will. 

 find several others in the elaborate history of ich- 

 thyology drawn up by MM. Cuvier and Valenciennes, 

 We shall confine ourselves, on the present occasion, to 

 those of Artedi, Linnaeus, Cuvier and Valenciennes, 

 Bonaparte, and Oken. 



(73.) One of the primary divisions in the system 

 of Artedi (1738), as before mentioned, is composed 

 of the Cet(2, or aquatic Mammalia. The other four 

 are characterised as follows : — 



Tail perpendicular, fins supported by rays.

Malacopterygii. 

 acanthopterygii. 

 Branchiostegi. 

 Chondropterygii. 



The first order, or the Malacopterygii, are arranged in 

 six divisions, according to the number and position of 

 the dorsal fin; while the Acanthopterygii are merely di- 

 vided into those having the head smooth or rough. The 

 genera are as follows : —
