There are eight rays in the membrane of the gills, fix- 
teen in the peCtoral fin, fix in the ventral, twenty-four in 
the anal, and thirty-one in the dorfal. The body is 
thin; the ground-colour filver relieved by fix bands,of 
deep blue, the upper one but weak. The pupil of the 
eye is black, iris yellow. The branchial membrane is hid 
under the covert. The lateral line runs near the back, 
and forms a fimilar arch. The pectoral and ventral fins 
are black; the others dark blue. This is alfo found in 
the waters of South America, and is good food. 
40. Chastodon Mauritii, or Prince Maurice’s chastodon; 
three fpines in the anal fin, and eleven in the dorfal, form 
the fpeciiic character. There are fourteen rays in the 
peCtoral fin, fix in the ventral, thirteen in the ana], 
eighteen in the tail, twenty-three in the dorfal. The 
body is covered with fmall fcales ; the mouth is large, 
the iris of the eye filvery white, inclining to yellow : 
the noftrils are below, and very narrow. The aperture 
of the gills is wide, and the membrane is hid under the 
covert. The back is arched, and of a deep blue colour; 
the belly is white; and over the fides, which are light 
blue, pafs fix black bands. The ventral fins are yellow ; 
the pectorals dark blue'; the others dark blue at the ends, 
and reddifh at the bottom. Prince Maurice found this 
fpecies at Brafil. It grows two feet long.: the flefli is 
white, and well-tafted. 
41. Chastodon Bengalenfis, or Bengal chetodon. Spe¬ 
cific character; banded body, two fpines in the anal fin, 
and thirteen in the dorfal. There are four rays in the 
membrane of the gills, fixteen in the pedtoral fin, fix in 
the ventral, fourteen in the anal, eighteen in the tail, 
twenty-five in the dorfal. The body is broad ; the 
ground colour blue, with' five chefnut-coloured bands. 
The fins are brown at their origin, and blue at their ex¬ 
tremities. The Icales on the head and fins are fmall, 
thofe on the body large. The opening at the gills is 
wide, and the membrane is concealed under the oper¬ 
culum. The eyes have a black pupil, furrounded by a 
white iris inclining to yellow. This fpecies is peculiar 
to Bengal, whence its name, 
42. Chastodon ciliaris, the hairy angel-fifh. The fpine 
in the cheek, and the briftly edges of the Icales, form the 
fpecific charadter. There are fix rays in the membrane- 
of the gills, twenty in the pedtoral fin, fix in the ventral, 
twenty-two in the anal, fixteen in the tail, and thirty- 
five in the dorfal. The bead and fins are furnifhed with 
fmall fcales ; the body with large ones; the capillary ri- 
fings, which begin at the middle of the fcales and pafs be¬ 
yond their extremities, are very remarkable, and give the 
fpecific name. The aperture of the mouth i9 fmall 5 the 
jaws of equal length, the lips ftrong; between which and 
the eyes are four round apertures. The eyes have- a 
black pupil; the iris is white inclining to red. On the 
back, which is dark grey, and juft before the fin, is a 
black ring. The fides are grey 5 the fins the fame, edged 
with brown; and the belly is white. The cheeks are 
jagged, and near the long fpine are two fhorter ones; the 
aperture of the gills is wide, and the membrane is in part 
concealed. This fpecies is front the Eaft Indies; they 
are caught about the ifland of St. Croix, and are much 
efteemed by the.inhabitants. The flomach is large and 
wfide, of a bent form ; the food is little crabs, which are 
often found half-digefled therein. The inteltinal canal 
is very long, with a great many flexures, and is faftened 
to the mefentery, as in quadrupeds. The air-bladder is 
ltrong, and faftened to each fide, as in the perch. Nei¬ 
ther ovary nor feed-veffels have been difcovered : indeed 
the fill) is very imperfectly known in Europe. 
43. Chastodon oCto fafciatus, or eight-banded che- 
todon. Specific character, eight tranfverle bands on the 
body, eleven fpines in the dorfal fin. There are fixteen 
rays in the peCtoral fin, fix in the ventral, fixteen in the 
anal, twelve in the tail, twenty-eight in the dorfal. The 
head is fmall; the jaws protrude, but are of equal length. 
'J he iris of the eye is white inclining to yellow j in front 
a 
O D O N. 
of which are two round apertures. The ground-colour 
is white inclining to violet; the bands are brown, lying 
two and two together. The anal and dorfal fins are edg¬ 
ed with brown, the others with grey. This is an Eatt- 
Indian fifh, and Linnaeus regards it.as a perch-, but it is 
evidently a chetodon, for which reafon we have followed 
Bloch’s claffification. 
44. Chastodon annularis, the ring-chetodon. Specific 
character ; the body flriped longitudinally, with a circle 
or ring on the lateral line near the head. There are fix¬ 
teen rays in the peCtoral fin, fix in the ventral, twenty- 
eight in the anal, fixteen in the tail, forty-one in the 
dorfal. The ftripes are fix in number, not ftrait, and of 
a light-blue colour. The ground-colour of the fifh is 
brown, the fcales are fmall. The iris of the eye is filvery, 
and near the eyes there are four fmall apertures. The 
gill-covert is double ; the upper lamina jagged and armed 
■ with a fpine. The peCtoral, ventral, and tail, fins, are 
white; the anal and dorfal black : the former is rounded, 
and has a blue band; the latter ends in a point. This is 
from the Eaft Indies ; and is good food. 
45. Chastodon coilare, the collared chetodon: five 
bands round the head (two white, the others black), and 
twelve fpines in the dorfal fin, form the fpecific character. 
There are four rays in the membrane of the gills, fourteen 
in the peCtoral fin, fix in the ventral, twenty-four in the 
anal, twenty in the tail, and forty in the dorfal. The 
jaws are protruded; the eyes are large, with a black pupil, 
blue iris, and a membrane ; juft below there are two little 
holes. The forehead goes .down with a lteep declivity. 
The fcales are fmall on the head and fins ; but very large 
on the body. The fides and back are blue ; the belly yei- 
lowifh. The peCtoral fin is yeliow, the ventral grey, the 
reft yellowifh edged with brown. There is a yellow band 
on the dorfal fin, and a brown one acrofs tire tail. This 
fpecies is very fmall, and is a native of Japan. 
46. Chastodon meloleucus, or mulatto chetodon: a 
black band over the eye, the gill-covert armed with a 
fpine, and twelve fpines in the dorfal fin, form the fpeci¬ 
fic character. There are fixteen rays in the peCtoral fin, 
fix in the ventral, twenty one in the anal, fixteen in the 
tail, twenty-nine in the dorfal. The body forms an ob¬ 
long rounded figure, aud is covered with fmall fcales. 
The for e-part is white inclining to blue : the back part 
black; the dorfal and anal fins are dark, the reft light. 
The eyes are large,, and juft in front of them are two ob¬ 
long apertures; the gill-covert confifts of two fmall la¬ 
minae ; and beneath the large fpine feveral fmall ones ap¬ 
pear; the aperture is large, and the membrane partly 
loofe. This is alfo a fmall f pecies, and was received from 
Japan by Bloch, in' whole work only a delcription of it 
is found. 
47. Chastodon velifer, the fail-finned chetodon. The 
teeth ferrated and cutting, and one fpine in the tail, form 
its fpecific character. The body is compreffed, party- 
coloured, and has leven fins. It inhabits the feas of 
both the Indies. The head is fmall, blunt, and ends in 
a blunt fnout; the mouth is fmall, the lips large; the 
jaws are armed with only one row of hollowed jagged 
teeth. The noftrils are fingle, and near the eyes. The 
pupil is black, with two irides ; one blue, the other yel¬ 
low. The gill-coverts are united ; the aperture is wide, 
the membrane concealed. The ground colour of the bo¬ 
dy is white, covered with brown bands, like molt of the 
other chastodons. The belly goes off {harp ; the back is 
rounded. The dorfal and anal fins form each a half-cir¬ 
cle, fomewhat like full-bent fails ; whence its name : and 
are ornamented with round blue fpots. The fpine of the 
tail is enclofed in a flieath; it is moveable, and the point 
is direded upwards towards the head of the fifh. The 
rays of the peCtoral fins are foft and ramified; the anal 
fin has two prickly rdys, the dorfal three, the tail four 
on each fide; the reft of the rays of thefe fins are foft. 
Bloch makes a leparate genus of this, under the name of 
acanthuriis,
