of the fresh specimen is contained nine and a quarter times in 
the same. 4th, that the diameter of the eye is only twice in the 
muzzle : in the Australian sort it is sensibly more. 5th, that 
the eye is near the superior profile of the head, and distant from 
the lower one by twice its diameter : in the new sort this last 
proportion is contained three times. 6th, that the European 
sort is, when fresh, of a silvery grey, rather brown on the back, 
and whitish below ; that the first dorsal, the pectorals, and the 
ventral, were of a rather fine red, and the other fins of a reddish 
brown : in the Australian fish the upper parts were of a fine 
blue, changing to green ; the sides and lower parts of a dirty 
white, rather silvery ; the dorsal, anal, and ventrals reddish ; the 
pectorals white, with their extremity dark ; the prseoperculum 
has no denticulations, but towards its angle there are some sinu- 
osities or notches ; this may depend on age. 
The teeth on the upper jaw are of two sorts — 1st, an external 
line of large conic ones ; they are rather curved backwards, and 
placed at a considerable distance one from the other in rather an 
irregular way ; they number about twelve on each side ; those in 
front are the largest, and they become very small as they extend 
backwards. Behind these is a band of villiform teeth, formed of 
four or five very irregular series; these teeth are small, obtuse, 
and directed backwards ; they are not so numerous in front as 
towards the posterior part of the mouth, but a few larger ones 
are seen in this part. At the lower jaw there is only the ex- 
ternal line of large irregular teeth, fourteen or fifteen in 
number ; at the anterior part there are two extra ones placed in 
front of the others ; the inside of the mouth and the tongue 
are smooth. 
The orbit is oblong, being one-fourth longer than its 
breadth. 
The scales Avhich cover the head are much smaller than those 
of the body ; these are densely punctured, and have concentric 
lines ; they are externally edged with a sort of a little Sciffina 
fringe. The lateral line runs over about sixty-eight scales, but 
their oblique disposition renders it difficult to count them with 
certainty. The head is four times in the total length ; the eye 
yellow, with a narrow golden circle.
