DOUBTFUL ORTHOGRAPHY. 87 



" Cowanyung "* {Decapfenis leptosomus). 



Though the young fry of this species are always present 

 in greater or lesser numbers in our harbor and estuarine 

 waters, the adults are not so often seen. The reason for this 

 is that the adult fish is essentially pelagic in habit, and roams 

 freely in our outside coastal waters. At times vast shoals 

 of these put in an appearance — their individuals ranging up 

 to as much as 18 inches or more in length. Our knowledge 

 in regard to the periodicity of this species (as in the case of 

 a number of others, amongst our pelagic fishes) is unfor- 

 tunately not sufficiently advanced to enable us to speak 

 authoritatively in regard to its movements, but ample evidence 

 is available to show that it may be looked upon as one of 

 the important fishes of the future — and there is no good reason 

 why it should not be the near future. 



In a general way, the young of the Cowanyung may be 

 distinguished from the common Yellowtail, among which they 

 are often captured, by the more rounded and shallower, 

 elongate body, and by the general greenish hue of the upper 

 parts; the latter being light-brown or Yellowish in the yellow- 

 tail. 



Trevally {Caranx georgianus). 



Plate LVII. 



This is the common " Trevally " of the Sydnej' fish 

 markets, where it is almost constantly to be seen. It is 

 captured in large numbers by means of hauling-nets, in most 

 of our coastal inlets, always commanding a ready sale in the 

 markets. Notwithstanding its great abundance in the inlets, 

 it is to a certain extent a pelagic fish, making its appearance 

 at intervals in prodigious shoals. The trevally is a smooth- 

 skinned and small-scaled fish, deep-bodied and slab-sided. It 

 grows commonly to a fine marketable size, the ordinary run 

 of what are usually termed large Trevally averaging about 

 2 or 3 pounds in weight. Much larger ones than that size 

 are, however, often obtained, and examples of as much as 

 9 pounds in weight, with a length of about 2 feet 6 inches, 

 have been obtained.
