PISCES THORACICI. SCOMBER. 
31 
The head rather obtuse, the mouth and eyes as usual; teeth linear, numerous, equal. Tongue, short, ovate, 
long, free, rough; palate and throat rough. Opercula rounded. 
The trunk. The back gently arched, carinate; the sides compressed, but convex; the breast carinate, the 
abdomen flattish. The lateral line beginning at the upper edge of the opercula, rises for about an inch, then 
sloping to the middle of the trunk, forms a small angle above the pectoral fin, after which, it is middle and 
straight to the end. The anus nearer to the head than the caudal fin. 
The fins. The first dorsal, in a groove, consists of seven spines, which when raised point alternately to 
opposite sides; the second, of five ramous rays with sixteen pinnulae, the first six connected by the common 
membrane, the others by a very slender one; but it is remarkable of these pinnulae, that each at its root seems 
to spring from a pyramidal protuberance not found where the pinnulse are quite distinct. The same remark 
belongs to the second anal fin, which consists of six rays and fourteen united pinnulse; the pectoral and ventral 
fins very short; the caudal deeply divided, and slightly falcate. 
The colour. The upper part of the head dark blue, the rest glossy white, but the edge of the opercula 
yellow. The upper part of the back still darker, but brightens towards the lateral line, above which is a row 
of five or six darkish spots; under the line, the colour completely yellow. The dorsal and caudal fins are a little 
lighter than the back; the edge of the latter is of a pale yellow ; the pectoral yellow above, at the root black. 
The length, two feet four inches. 
No. CXLI. 
Scomber pinnulis dorsi tredecem unitis ; cauda Jalcata; corpore alepidoto, toto sub-asp era ; 
maculis sex rotundis ad lineam lateralem. 
The Scomber with thirteen united dorsal pinnulae ; the tail falcate ; the body without 
scales, but all over somewhat roughish ; six round spots on each side above the 
lateral line.

This species differs chiefly in the following circumstances from the one last described. The head sharper; the 
roughish skin extends over the whole trunk, below as well as above the lateral line; the lateral line carinate, 
and the tail more falcate. 
The colour. The upper part of the head greenish, opercula pearl; the ridge of the back dark blue, fading 
into a yellowish white below the lateral line : six round spots above the line, less dusky than in the last fish. 
The dorsal and caudal fins darker blue than the back; the pectoral yellow; the ventral and anal fins whitish. 
Length. The subject described measured sixteen inches, but they are sometimes brought double that size. 
REMARKS. 
Though the second dorsal and anal fins are marked with a spinous ray, it should be observed that the spine, 
lying close on the second ray, seldom pierces the skin, and in such case is often omitted by the painter. In the 
present instance I follow my original memoranda, which mark spines, though perhaps improperly.
