Zoology.-] NATURAL HISTORY OF VICTORIA. {Fishes. 



The gullet is wide ; the stomach with a wide blunt csecum ; the 

 pyloric appendages about eleven in number, and § of an inch long ; 

 the intestines with two turns. The swim-bladder is excessively 

 thin, club-shaped, and about 1J inches wide. Liver bilobed. 



The general hue, like the fashionable color " old gold," is a most 

 striking and beautiful characteristic of this fish, when fresh, distin- 

 guishing it from the many other Murray-River fish with which it 

 comes plentifully to the market, and well warranting its popular 

 name amongst the colonists of "Golden Perch." It has not been 

 figured of its natural colors before. 



Common in the River Murray and its branches, but not found 

 in any river of Victoria flowing southwards to the sea.
