DOUBTFUL ORTHOGRAPHY. 87 
“ Cowanyung ”* (Decapterus 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 nét 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 (Caranz georgianus). 
Puate LVII. 
This is the common “ Trevally”’ of the Sydney 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 
9g pounds in weight, with a length of about 2 feet 6 inches, 
have been obtained. 
* The correct rendering of this name is doubtful.
