Branchial opercula without scales, the anterior lamina covered with a fleshy muscle, the posterior shaped like 
a quadrant. The branchial membrane half discovered, the two inferior rays much curved; the aperture 
rather small. 
The trunk. The back straight, round, the side convex; the throat flat, the belly prominent; the tail round, 
compressed. No lateral line to be distinguished. The anus middle, between the head and the tail. 
The Jins. Two dorsal, the first scapular, of six rays with the soft points rising above the membrane; the 
second lumbar, of eleven declining ramentaceous rays; the pectoral broad and pointed. The ventral united 
in the manner peculiar to this genus. The anal has ten assurgent rays, shorter than those of the second dorsal. 
The caudal fin is ovate, with a small point. 
The colour a dull yellow, variegated on the sides, with large dark spots ; the belly white. The rays of the 
dorsal and pectoral fins dotted with black; the other fins of a darker yellow than the body, but without 
dots. 
In a smaller subject some dots were found on the pectoral and caudal fins. 
Length from the nose to the caudal fin, one foot. 
Length of the longest ray of the caudal fin, two inches and a half.

This species, including the tail, generally measured five inches. Its colour pale brown, with a few azure dots 
scattered on the sides ; the belly whitish. Five black marks were observed on the lateral line, as in the last 
species, but of a lozenge-shape; the form of the caudal fin was very different, and the fins were not spotted.
