T h e body oblong, compressed, squamous; the scales somewhat square, rounded behind, imbricate, tenacious.
The bead ovate, small, compressed, declivous, mostly squamous; rostrum naked. The mouth low, small,
horizontal; lips thickish. Jaws short, extractile, the upper longest. Teeth numerous in both jaws. Tongue
somewhat round, smooth, not tied; palate tuberculate in the fore part. Eyes high, large, orbicular, iris of a
yellowish white. Nostrils large, oval, near the orbit.
The opercula squamous, the first lamina serrated. The branchial aperture large, arched, the membrane
The trunk. The back rises in an arch, carinate; the sides compressed; the breast convex, but the belly
nearly straight; the tail broad and long. The lateral line less arched than the back, becomes straight where
the dorsal fin ends. The anus much nearer the head than the tail.
The fins. The dorsal spines, the first two excepted, long, and form a high arch; the ramous rays declining
are much shorter; the pectoral long, slightly falcate; the end of the first ventral ray setaceous; the second
anal spine remarkably large ; the caudal not deeply bifid.
The colour. There are five or six longitudinal fillets, yellow, and dusky brown, on the sides ; the breast and
abdomen white; the pectoral and dorsal fins near the roots dotted with black.
The lengtb, ten inches.

T he head in this species is longer and sharper than in the last; the body less arched; the breast and belly
flatter; the lateral line rises in a higher arch; and the scales on the trunk, besides being larger, are striate on
the shoulder. In other characters they in general agree.
The Jns. The dorsal spines are shorter than in the last, and the ramous rays are assurgent, forming a
rounded point; the pectoral lanceolate and somewhat falcate; the spine of the ventral fin unusually large;
the ramous rays of the ventral form a rounded point like the dorsal; the caudal emarginate, or a littie shorter
at the middle.
The colour. The upper part of the head a dark red, brightening on the cheeks and opercula to pink; the
lips red. The back darker tlian the head, but gradually fades into a reddish white, which is the colour of the
breast and abdomen. T he dorsal fin a very light gray, with a purple margin, the white points of the spinous
rays appearing above the margin. The pectoral are pink; the ventral and anal like the dorsal, but with a
broader border of lighter purple; part of the tail pink, the lower lobe purple.
The length of the subject described, one foot four inches.

T he body ovate, compressed, covered with very small, firm, sub-orbicular scales. The head completely
squamous, declivous, the rostrum short, obtuse, projecting a little over the mouth. Mouth low, horizontal,
large; hardly any lips. Jaws extractile, the under .shortest, both full of teeth. Teeth above distinct, regular, a
little curve; below more crowded, in front tuberculous, and behind aceróse. Tongue short, roundish, smooth,
free. Palate without teeth. Eyes nearer the rostrum than the crown, large, orbicular. Nostrils double, in a
groove near tlie orbit; the posterior (as usual) largest.

The trunk. The back carinate, the abdomen rather flat. T he lateral line from the upper edge of the
