i. Chaetodon Suratenfis., or Surat chetodon, Nineteen 
fpines in the dorl'al and thirteen in the anal fin, form the 
lpecific character. The membrane of the gills has five 
rays, the ventral fin fixteen, the anal twenty-three, the 
tail fixteen, the dorl'al thirty-one. The aperture of the 
mouth is finall ; the lips flefhy ; the noftrils, which are 
midway between the mouth and the eyes, -are tingle and 
round ; the roltrum declines ; the iris is filvery. The 
aperture of the gills is wide, the membrane is loofe, and 
fuftained by five linall jagged bones. The lateral line, 
which paffes along the body near the back, is loft towards 
the end, and appears again about the middle of the tail. 
There is a black fpot near the gill-covert, under the pec¬ 
toral fin. .The ground-colour of the fifh is white, cloud¬ 
ed with violetand there are a vaft number of beautiful 
round filvery fpots, and fix brown flripes or bands, the 
firft of which reaches only to the pectoral fin. The anus 
is nearer to the head than to the tail. The ventral fins 
are black; the dorfal and anal, all along the fpines, are 
violet, but the foft parts are grey ; the fpines of thefe fins 
are provided with foft broad filaments. It is a native of 
the leas about Surat, and is reprefented in the annexed 
Chaetodon Plate I. They frequent the mouths of rivers 
in November, when they are taken pretty plentifully with 
the line. This grows fifteen inches long; the flefli is 
fat and well-tafted, either fried or boiled. At Tranque- 
bar, the Portuguefe eat them on faft-days, keeping them 
dried for that purpofe. They fpawn in February. 
a. Chaetodon Chinenfis, or Chinefe chetodon : with 
eighteen fpines in the dorfal fin, which conftitutes itsfpe- 
cific character. The membrane of the gills has five, rays; 
the pedtoral fin ten, the ventral fix, the anal twenty-eight, 
the tail fixteen, the dorfal twenty-four. This fifh is broad 
in the middle, compreffed at the ends. The head and 
mouth are linall; the iris of the eye is bluilh ; on the gill- 
covert there is a black oval fpot, with a white rim ; there 
are two fimilar fpots between the gill-covert and the eye. 
The branchiollege membrane is hid under the gill-co¬ 
vert. The lateral line runs parallel with the back ; the anus 
is near the head. There are ten brown narrow bands on 
a white ground round the body of this fifh, feveral of 
which are divided.. The pe&oral and ventral fins are 
grey ; the reft violet-colour ; the dorfal and pedtoral fins 
are fliort; the anal long; there are fifteen fpines in the dor¬ 
fal fin. It is one of the fillies which the Chinefe take by 
means of the tame guillemot or diver, which birds are 
trained for this fport. 
3. Chaetodon Kleinii, or Klein’s band fifh. A ftripe 
acrofs the eye and head, and feventeen fpines in the 
dorfal fin, form the fpecific charafter. The membrane 
of the gills contains fix rays, the peftoral fin fifteen, the 
ventral fix, the anal twenty-three, the tail eighteen, the 
dorfal thirty-fix. This filh is of a globular form ; the 
aperture of the mouth is very fmall ; the noftrils fingle ; 
the pupil of the eye is black; the iris white; the gill- 
covert is competed of two thin leaves ; the aperture is 
wide, and the membrane loofe. The ground-colour of 
the body is white ; the back is brown; the fins gold- 
yellow. This fpecies is found in the Eaft Indies. Klein 
was the firft who defcribed this fifh, and gave a figure ofit. 
4. Chaetodon bimaculatus, or the two-fpotted cheto¬ 
don. Two. fpots on the dorfal fin, and a ftripe acrofs the 
eyes, form its fpecific character. The membrane of the 
gills is provided with fix rays, the peftoral fin with four¬ 
teen, the ventral with fix, the anal with eighteen, the tail 
with feventeen, and the dorfal with thirty-four. The 
jins are oblong ; the noftrils double, and placed near the 
eyes; the pupil of the eye is black, the iris yellow. The 
aperture of the gills is wide, and the membrane is con¬ 
cealed. The colouris white, inclining to grey ; the pec¬ 
toral and ventral fins are red, the others yellow at their 
origin and grey at the extremities. The band and the 
fpots are edged with black and white ; one of the fpots is 
at the bottom, and the other at the edge, of the dorfal fin. 
Native of the Eaft Indies.

5. Chaetodon biaculeatus, or two-fpined Chetodon. 
The two fpines under the eye furnifh the fpecific charac¬ 
ter and the name. The'membrane of the gills has four 
rays, the peftoral fin eighteen, the ventral fix, the anal 
and tail feventeen each, the dorfal twenty-feven. The 
body is long; the back of a blue colour, the belly white. 
It is girt with three bands : the firft encompafles the 
head, theTecond the body, the third’the fail. The iris 
of the eye is of a brown hue. The hindermoft of the 
two fpines which are below the eye is much longer than 
the other. The two gill-coverts are jagged ; the lateral 
line goes near the back ; the anus is in the middle of the 
body. The fins are all grey, and vary only in fhape ; 
the peftoral and anal being round, the reft fharp ; the 
dorfal fin has ten fpines; and a furrow in the middle ; the 
anal fin has two fpines, the dorfal only one. This alfo 
is found in the Eaft Indies. 
6. Chaetodon aureus, or the golden chetodon; the 
beautiful yellow colour of which, and the ftrong fpine 
with which the jaw-bone is armed, form the fpecific cha¬ 
racter. There are twelve rays in the peCtoral fin, fix in 
the ventral, fifteen in the anal and tail, and twenty-four 
in the dorfal. The body down to the tail forms an oval 
figure ; and except on the peCtoral and ventral fins, it is 
covered with hard jagged fcales. The mouth is linall, 
with fetaceous teeth; the lips are ftrong; the noftrils dou¬ 
ble, not far from the eyes; the pupil of the eye is black, 
the iris reddifli. The gill-covert is a fingle plate, and 
goes off to a point near the peCtoral fin : the aperture is 
large, and the membrane lies concealed under the covert. 
The origin of the fins is yellow, the extremities green. 
There are twelve fharp fpines in the dorfal fin, and 
two in the anal; the rays of all the fins are branched; 
the tail and peftoral fins are round, the others are fickle- 
fhaped. It inhabits the waters of the Antilles; and is 
carnivorous, being furnilhed with teeth proper for feizing 
its prey. 
7. Chaetodon imperator, or imperial chetodon; the 
body ftriped longitudinally, and the fourteen fpines in 
the dorfal fin, form the fpecific character. The rays in 
the peCtoralfin are eighteen in number, in the ventralfix, 
in the anal twenty-three, in the tail fixteen, in the dorfal 
thirty-four. The head is large, and covered with fmall 
fcales ; the eyes have a black pupil, and orange-coloured 
iris; and round the iris is an arched blue ftripe. The 
jaw-bone is edged with blue, and armed with a ftrong 
fpine. The gill-covert is made up of two laminae, with a 
blue ftripe upon each. The ground-colour of the fifth 
is white ; tire longitudinal ftripes are blue. The dorfal 
and anal fins' are thick, itiff, and round; the latter 
at its origin has three fliort ftrong fpines; the ventral fin 
has one long one; all the fins have branched rays. It is 
a native of japan, and the belt of all the Eaft-India fifh: 
they are very fcarce and dear, and only found on the 
tables of the great: whence the name. 
8. Chsetodon fafciatus, or ftriped chetodon. The fpe¬ 
cific character is, the fafciated, fwathed, or lifted, body, 
and fever, fpines in the anal fin. The pefioral fin has 
fixteen rays, the ventral fix, the anal twenty-one, the 
tail fourteen, the dorfal twenty-three. The head, the 
fcales, and the aperture of the mouth, are finall ; the 
jaws are of equal length, and furnifhed with teeth. 
The lips are hard; the noftrils double, and near the eyes; 
the pupil is black, the iris blue and white. There are 
blue ftripes on the forehead, above, below, and behind, 
the eyes.' The maxillary bone is jagged, and terminates 
behind in a ftrong fpine. The gill-covert is one thin 
plate ; the aperture is wide, the membrane hid. The 
colour is white, with blue ftripes, edged with brown. 
The pectoral fin is fhort, tranlparent, and rounded ; 
there is one fpine in the ventral fin ; and fourteen in the 
dorfal; the reft of the rays of the fins are foft and rami¬ 
fied. The blue bands round the anal fin have not the 
brown edge remarked in thofe on the trunk. This fifli, 
which the Japanefe call the duke, probably an-accou'nt of
