Mr. Wilson has tried to naturalize tlie Murray Cod in the 
rivers of the AVimmera, but I believe without result. The 
Acclimatisation Society has been more successful in its endeavours 
to place it in the Tarra, and it seems to have considerably pro- 
pagated in that river ; for, although no large specimens have yet 
been found, small ones are seen rather frequently. The fish 
seem to go down towards the sea, as Captain Sinnott most kindly 
sent me a small specimen he caught in his dock, where the water 
is already brackish. It is a little less than three inches in 
length ; its colour is of a light grey, and the upper part of the 
body is covered with small black spots ; the dorsal and the base 
of the caudal are yellowish, and the extremity of the caudal rather 
dark. 
The Murray Cod, as almost all the Australian fresh- water fish, 
is often marked with red spots, caused by intestinal worms. 
Not A. — A young specimen, obtained in January, 1872, and 
measuring six inches long, presented the following dimensions : — 
Height four times and two-thirds in total length ; head three and 
one-third in the same ; eye four and one-half in length of head. 
It was of a light lilac on the back, with the lower parts of a 
dirty white. On the sides and on the back were numerous 
irregular blotches of a dark purple. 
DHLES. 
This genus was established by Cuvier and Valenciennes. The 
Australian sorts inhabit the rivers of the interior.
