The second division of the fish, according to Cuvier's arrange- 

 ment, or the Malacopterygii, includes the bulk of Agassiz's 

 Cycloidei, together with some families belonging to the other 

 orders of the latter naturalist, as the siluroidei and sauroidei 

 which rank with his Ganoidei, and the platessoidece or j)leuro- 

 nectoidecs which he places among his CTENoroEJE : on the 

 other hand, we have already noticed that Agassiz's Ctenoide^ 

 include the scomber oidece, atherincB, mugiloidece, and lahroidece, 

 considered by Cuvier as Acanthopterygians. 



The Malacopterygii abdominales embrace the greater 

 part of the fresh water fish, and though few species are common 

 to Europe and North America, there is much similarity between 

 the generic forms existing in the waters of the two continents. 

 As the lakes and rivers, however, occupy more space in propor- 

 tion to the land in North America than in any other quarter of 

 the world, so the number and variety of fresh water fish is 

 greater than in Europe, or any other extra-tropical country.
