round the posterior part of the body, and joins the anal, which 
is formed of about one hundred and twenty rays. 
The height of the body is about eighteen times in its length ; 
tbe muscular flakes are very visible, and form arched lines all 
along the body. 
The upper parts of the body are of an olive green, with the 
belly of a blueish white ; the sides are silvery, and the head is 
purple ; the fins are olive green, the dorsal and anal having a 
black border. 
I believe this sort to be the Sabenatus of Richardson, and 
that the slight differences in the disposition of the teeth are 
caused by age, as his specimens seem to have been older than 
mine. 
Total length ten inches . 
Only seen once in the Melbourne Market, in the month of 
September. Dr. Richardson’s specimen was from New Zealand.
