PISCES THORAGICI. CHLTTODON. 
possesses that part of the back which descends abruptly to the tail, and consists of sixteen soft, declining rays. 
The dorsal as well as all the other fins, except the pectoral, are covered with scales from the roots for some 
way upwards. The pectoral low, short, broad, declining; the ventral behind the pectoral, the second and 
third rays fibrous; the anal spines four, very strong, the other part of the fin resembles the soft rays 
of the dorsal; the caudal fin almost equal, the three middle rays only a little longer than the rest. 
The colour of the fish a darkish grey which brightens towards the belly; the breast yello wish-white; the 
sides variegated by numerous round, black spots, as are also part of the dorsal, anal, and caudal fins. The 
rays of the fins in general darkish ; and it may be remarked that the soft rays of the dorsal and anal fins, as 
well as the tail, remain expanded after death. 
The length from the rostrum to the caudal fin nine inches; the broadest part of the trunk, six inches, 
three lines. 
REMARKS. 
This fish seldom, or never, appears at the European tables at Vizagapatam. Bloch mentions it as a 
remarkable circumstance that petrifactions of this species are found in the mountains of Bilka in Italy.

The body somewhat orbicular, much compressed, nearly as broad as long. The scales oval, imbricate, and 
cover part of all the fins, except the pectoral. 
The head large, much compressed; from the knob between the eyes to the rostrum very steep, without 
scales, except the front. The mouth low, very small, terminal, horizontal; lips thickish. Jaws extractile, the 
upper a little longer than the under; the teeth setaceous, numerous, close, equal; the tongue oblong, smooth, 
retracted, tied. The palate smooth. 
The eyes supreme, distant from the point of the rostrum, large, orbicular, not prominent. The opercula 
smooth, without scales, the posterior leaf ciliate, acuminate. The branchial membrane exposed; the aperture 
large, lateral. 
The trunk. The back assurgent and carinate to the dorsal spines, where it rises into a sort of hump and 
then descends gradually, but convex, to the tail; in the opposite direction, the line from the lower jaw to the 
anal fin, inclines gently, and then ascends circularly. The sides much compressed; the tail thin. The 
lateral line springing from the upper edge of the operculum, forms rather a lower arch, than in the former 
fish, but in like manner becomes straight near the end of the tail. The anus equidistant, oval. 
The Jins. The three first dorsal spines very short and small, and none of them nearly so robust as in the 
last fish, the soft rays form an arch. The pectoral fin very long, falcate. The first and second ventral rays.
