320 Transactions. — Zoology. 



The Piako Eiver is here about 60 yards wide, and one can 

 form some idea of the quantity of fish going up and down 

 when such a number and variety can be taken out of a bit of 

 water only 5 yards wide. At high tide the water is almost 

 salt, but only slightly brackish when low. 



I have never heard of either the young of the rock or red 

 cod coming from fresh water before. There is absolute cer- 

 tainty about the specimens caught being the young of the red- 

 cod (named "rarii" by the natives). In the one I am sending 

 you will notice the two feelers hanging from the throat. 



I also send some of what I suppose are pilchard ; one is 

 very much deeper in the body. What I take to be rock-cod 

 were all too large to be put in the bottle.
