278 The Hiflory of ANIMALS. 
_ i 
This is a native of the American Ocean, and is caught among the other already de¬ 
scribed fpecies ; but, though we meet with it frequently in the cabinets of our collec¬ 
tors, none of the writers on fifties have accurately defcribed it. 
Chcetodon macrolepidotus , lineis utrinque duohus nigris, offtculo quarto pin - 
nae dorfialis longijjimo fetiformi. 
The Chcetodon , with oblong ficales , and with two black lines on each fide 5 
and the fourth ray of the back fin long.

The head of this fpecies is longer than that of the laft, and the roftrum obtufe: 
the lower jaw is fomewhat longer than the upper, and the whole head is narrower 
than in any of the other fpecies: the eyes are large, and hand but at a fmall diftance 
from one another; their iris, is white, and the pupil of a greenifh black; the o bits 
are fomewhat acute in the upper part: the apertures of the gills are larger than in ai¬ 
med: any other fpecies, and the middle lamina of their coverings is fomewhat ferra l ed 
on the lower part: there are in each jaw feveral feries of teeth, placed very clofe to 
one another, and flexible; and there are two prominences in the anterior part of the 
palate ; the reft of the palate is fmooth, and the tongue alfo is fmooth. 
The fcales are very large and thin ; they are of an oblong figure, fomewhat ftriated, 
rectilinear at the bale, but rounded, and fomewhat rough at the hinder edge : the head 
is of a ftlvery white, but there is a black line between the eyes, and a black fpot at the 
roftrum : the body is variegated with black and white, difpofed in tranfverfe lines. 
The back fin has thirty-feven rays, eleven of which are robuft and prickly; the 
others are foft, and are ramofe at the extremities; the fourth ray is fo very long, that 
it refembles a briftle, and is extended beyond the tail; the reft are very fliort: the 
pedforal fins are white; they have each eighteen rays, and they are fituated much 
nearer the back than the belly : the belly fins are black, and have each of them fix 
rays, of which the fir ft is prickly, broad, and robuft ; the reft are weak and ramofe : 
the pinna ani is broad, and rifes higheft toward the middle ; it has twenty-three rays, 
the three anterior of which are robuft and prickly, the others are foft and ramofe, and 
the middle ones are tallefi : the tail is white; it is nearly even at the extremity, anci 
has feventeen rays: the anus is much nearer to the pinna ani than to the ventral 
fins. 
This fifh is very broad, in proportion to it’s length, though lefs fo than the prece¬ 
ding fpecies. It is ufually about four inches long, and three inches and a quarter in 
breadth. It is caught on the Brafilian fhores. 
Chcetodon macrolepidotus , lineis utrinque tribus nigris, latis , linea quarta 
in cauda . 
The long-fcaled Chcetodon, with three black lines on each fide , and a fourth 
on the tail. 
This is alfo very broad, in proportion to it’s length, and is of a more deprefled fi¬ 
gure than almoft any of the other fpecies: the head is oblong, flender, and obtufe at 
the extremity, and is very declivous from the eyes to the roftrum : the eyes are large, 
and placed near one another, and their iris is of a ftlvery grey, the pupil black : the 
noftrils have each a double aperture ; the anterior one is a round foramen ; the pofterior 
a tranfverfe flit; they ftand nearer to the eyes than to the extremity of the roftrum : 
the openings of the gills are large, and the middle lamina is ferrated on the lower 
edges : the jaws are both of the fame length, but, when the mouth is open, the un¬ 
der one appears fomewhat the longer : there are in each jaw feveral rows of teeth, and 
in the anterior part of the palate there is a very large protuberance. 
The whole fifh is variegated in a very elegant manner with black and white : the 
whole anterior part of the head is white, and there is a black line on each fide near 
the eyes; behind this there runs another very broad white line : there goes a broad 
black line again, from the anus to the beginning of the back fin, and in the middle of 
the body there is a very broad white line; and in the middle, between the back and 
belly fins, there is alfo a black line : the hinder part of the body, and one half of the 
tail, are of a bright and elegant white j and the exterior edge of the back fin, and
