PISCES THORACICI. SCOMBER. 
The trunk. 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 branchiae 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, 
The fins. 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 pinnulse, but without the usual protuberances at the root: the mem¬ 
brane unusually thick. The 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 Chaetodon Rhomboides .-f
