Percoidete. — Of 500 species belonging to this family, which 

 are described in the Histoire des Poissons, two-thirds inhabit 

 the Indian Ocean, Red Sea, and warmer latitudes of the 

 Pacific ; 49 belong to the Mediterranean and eastern side 

 of the North Atlantic, and 118 have been detected on the Ame- 

 rican side of that sea. The North American famia embraces 

 one-ninth of the species composing the family, all, with the 

 slight exceptions we shall mention, peculiar to that country, not 

 one of them ranging to Europe. The exceptions are holocentnim 

 longiphuie, w^hich goes as far north on the American side as Ca- 

 rolina, but crosses the Atlantic within the tropics to Ascension 

 and St. Helena ; and trichodo7i Stelleri, which is found both 

 on the Asiatic and American shoi*es of the sea of Kamtschatka. 

 The last-named fish is the most northerly of the known Ame- 

 rican percoidece ; and the lucioperca Americana, which inhabits 

 fresh waters up to the 58th parallel, stands next to it in that 

 respect. The perca vulgaris being an inhabitant of the Sibe- 

 rian rivers, which fall into the Icy sea, is one of the most northerly 

 of the family, though the very nearly allied American species 

 have not hitherto been detected in a higher latitude than the 

 45th. With respect to the distriJmtiou of generic forms, 

 Europe nourishes nine, which are not known to exist in North 

 America, viz. lates, apogon, jwmatomiis, aspro, acerina, poly- 

 prion, traclnnus, sphyrcBna, andparalepis ; and North America 

 ten, which are not found in Europe, viz. huro. cenfropristes, 

 grystes, ce)itrarchus, jjomotis, hryttus, aphrodederus, trichodon, 

 holocentrum, ?c!\d polynemns., besides the doubtful genera propo- 

 sed by M.Rafinesque : only five are common to the two faunae, viz. 

 perca, lahrax, lucioperca, serraniis <x\\A uranoscopus. Grystes, 

 containing onlj^ two described species, forms another link con- 

 necting the American and Australian faunae ; one of the species
