“ In multis convenit Chat, macrolepidoto, Linn. Syst. 464, 14, sed differt specifice.” — Solander, MSS. 
In the Banksian drawing there is a short spine on the front of the upper part of each orbit, and 
the upper edge of the orbit is serrated: the posterior angle of the operculum is rounded. It differs also 
in the ground colour of the body having a yellowish tinge ; in the pectoral fins, the soft part of the 
dorsal and the caudal, being straw-coloured, and the ventrals deep black ; and in the colour of the 
tips and nose being less tinged with red. 
Of the specific distinction between the Hen. chrysostomus and the Hen. macrolepidotus, there can 
be no doubt. The chief differences in form consist in the want of convexity in the former in the rise 
from the eye to the dorsal fin; in the rapid declivity of the rays of that fin behind the fourth ; and in 
the elevation of the soft rays to a height considerably exceeding that of the adjoining spinous rays. 
The colours, although essentially the same, are, as it were, counterchanged in the two species, nearly 
all the parts which are dark in the one being pale in the other, and vice versa. 
The existence of a long filament at the end of the fourth ray of the dorsal fin appears to be indicated 
by the twisted form given to that part in the drawing.

PLATE XX. FIG. 2. 
A description and sketch of this fish were preserved by Mr. Collie ; and it is also mentioned in 
the notes of Mr. Lay. Mr. Collie describes it as “a long, tapering, rounded fish, without distinct 
scales, except in the middle lateral caudal ridges. The tail has two angular ridges converging 
posteriorly, one on each side of the middle lateral caudal ridge: the latter was more prominent on the 
right side than on the left. The teeth are laterally compressed, and of considerable breadth along the 
jaws, with the crown rounded : they form a kind of serrature. There are also small pointed teeth on 
the palate, and on the os hyoidesl The upper jaw is moveable; and when the mouth is opened, the 
anterior and superior part of the snout is directed upwards, the part of the jaw near the angle being 
depressed. The lower jaw, towards the angles, is overlapped for a considerable distance by the upper 
when the mouth is shut. The first dorsal fin has twenty-five spines, and is lodged in a groove of the 
back : the second has nine distinct pinnules, and one connected with the spinous portion by its thin 
membrane. The distinct pinnules stand upon a fine pedicle that spreads out a little from side to side, 
supporting upon its upper surface a thin triangular membrane. The anal fin corresponds to the last 
dorsal, and like it has nine separate pinnules, and one connected : the angular membrane of these is 
upon the lower surface of the pedicle." — C.
