NATURAL HISTORY OF VICTORIA. 



[Fishes. 



in large quantities in the cold months ; it occurs also at Sandridge 

 and at the mouth of the Saltwater River. The flesh is moderately 

 good for the table. 



The previously described species of Lates inhabit the Nile and 

 the mouths of some of the large Indian rivers. 



The following are the detailed measurements of a large 

 example : —

I have seen some specimens a little longer in proportion to the 

 depth, probably constituting the L. antarcticus of Count Castelnau, 

 and in one of them the teeth of the lower edge of the preoperculum 

 are partially directed backwards as he describes, but this seems in 

 my specimen to be an irregular growth from injury. 



This fish has not been figured before.
