tralici, much sought after by anglers. Takes the fly and the

 and short, and with an excavate snout. Body higlily compressed.

 up to the limits of brackisli water, and occasionally beyond. 

 Spawning time : about June and July. Spawns in the bays and 

 estuaries. Egg separate and pelagic. Grows exceptionally to a 

 weight of 4 lbs. Not much sought after by anglers. Very rarely 

 takes any artificial bait at all, and has never yet been known to

Much more might be written to show the differences existing 

 between these two species of /'e?'c«^a<es, but sufficient has been

 may mention that a considerable amount of material bearing on 

 this question has been, and is being, worked up, and will be 

 published later on.
