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



One of the most abundant of the food-fishes of Victoria in all the 

 warmer months of the year, disappearing in the cold weather. It 

 is not usually seen at the best tables, but is sold in great quantities 

 by hawkers round the suburbs of Melbourne. The younger ages 

 are very conspicuous in the fish shops by their yellow pectorals.
