terminate in a setaceous thread. The first and last anal spines short, the soft rays somewhat arched. The 
caudal fin intire, but the blunt projection in the middle rather more conspicuous. 
The fins remain expanded after death, as in the former fish. 
The colour of the upper parts a light gray, on a silvery ground, reflecting various tints in different lights, 
which growing lighter and lighter towards the belly, terminate in a rich mother of pearl. The knob between 
the eyes, the face, the opercula, and the breast look as if silverized; but what adds greatly to the beauty of the 
fish are small round spots of dark green and gold, disposed in regular transverse rows on the sides.

The body of this species in its form comes near the Latte. It is equally compressed and thin. 
The head in its form, as well as the face, agree with the Latte; the position of the eyes, the nostrils, and the 
mouth, the lips, the tongue, and the palate are alike in both ; but there is a variation in the teeth: the regular 
row is here wanting, the jaws only feel like a file, and in the upper are a few small curve teeth. There are a 
few scales on the lower part of the face, but the opercula are naked. The branchial membrane very visible. 
The trunk. The back assurgent as in the Latte; the hump less, and the declivity from the dorsal spines 
less curve. The belly part of the fish as in the Latte; the hinder part to the tail more in a straight line; the 
lateral line and the anus in form and situation the same in both. 
The Jins in situation and shape agree very nearly also with those of the Latte. The three last dorsal spines 
are longer, and the posterior part of the fin more completely arched; the three anal spines are distinct, 
seemingly not connected with the anal soft rays. 
The colour of the back gray, the face and belly silvery. The anterior part of the back, the membranes of 
the dorsal and anal fins, red; all the other fins are of a dull yellow; the opercula of a pale red.
