In living specimens the fish is of a silvery-grey, rather 
darker on the back, with a light coloured longitudinal streak 
on each side. On these latter parts there are numerous 
minute, white, round spots, placed at some distance one from 
the other. Fins rather yellow, with their end of a dark 
reddish brown; muzzle yellow ; eyes of alight blue; lower 
parts of the body white.

From the Murray. When living, it has a golden tinge all 
over the body ; the caudal is of a dark colour ; dorsal flesh 
colour, with the upper part of the soft portion obscure ; the 
anal similar ; pectorals almost red, ventrals rosy.

PROTOTROCTES MARCENA. 
Prototroctes Maroena, Gunther, Catal. v., p. 382. 
After two years' researches, I have at last obtained several 
specimens of this sort, which used to be very common in the 
Yarra, and is known as the Yarra Herring. I owe my first 
specimens to the kindness of Dr. Bleasdale. 
This fish is very silvery, with the upper parts of a light 
olive green ; dorsal and caudal of the same colour, bordered 
with a black tinge, the other fins white ; the eye is of a bright 
yellow ; the adipose of the colour of the back ; snout brown. 
It has a strong smell of cucumber. 
My specimens were caught in the beginning of April. 
Length of the longest specimen a little under eight inches, 
but I believe they a?« not full grown. It is said to be a very 
good edible fish. 
CH.ETESSUS EREBI. 
I find that it was by mistake that I stated that this fish 
inhabited the sea ; it is confined to the rivers of the interior, 
such as the Murray, the Darling, &c.
