The trmt. The back, to the beginning of the second dorsal fin, arched and carinate, it then descends
obliquely, the second dorsal occupying the declivity; the sides are a little convex, but compressed ; the abdomen
slanting, flat. The sides of the branchiæ somewhat rough, the exterior tuberculate. The lateral line {slightly
carinate) forms a low arch over the pectoral fin, then runs straight along the middle of the tail. The anus
nearest to the head
T h e / « . The first dorsal consists of six short spines in a groove ; the second of one short spine, and six
long rays united with fourteen rays like pinnulæ, but witltout tile usual protuberances at the root; the membrane
unusually thick. T he pectoral fins very short, broad, acuminate above ; the ventral half the length of
the pectoral ; the first anal fin in a groove ; the second has one short spine, and in other respects resembles
the opposite dorsal, the long rays in both being falcate ; the caudal completely falcate. Before the first dorsal
fin there is a recumbent spine, as in several of the preceding species.
The colour of the head and trunk above the line, a dark leaden ; the rest, including all the fins, excepting the
dorsal and exterior part of the caudal lobes, yellow.
Length, eleven inches.
REMARKS.
In a subject of twenty inches, the colour of the head and back was of a bluish-gray, and the parts below the
line, were white, instead of yellow. It is a dry insipid fish.
In the form of the dorsal and anal fins, the present fish resembles the Scomber Glaucus ;* but in its general
form it approaches nearer to the Chætodon Rhomboides.f
