inner surface of the fin dark blue, growing gradually lighter 

 outwards. 



During the season of 1896 I procured two specimens of this 

 graj'' mullet from among the scores of dohula exposed in the 

 market, these two having been taken respectively in Port Jackson 

 and Botan}'^ Bay; the largest measured 420 millimeters and is in 

 my possession. 



The great depth of this fish at once distinguishes it from 

 dohula — the only species with which it could be confounded — and 

 is the more remarkable because the examples of that species, in 

 whose company my two specimens were taken, were all distended 

 with more or less fully developed roe, while in these no signs of 

 breeding could be discerned.
