Form oblong, oval, rounded in front, gibbous on the back ; 

 height of body three times and one-eighth in the total length, 

 length of head nearly four times in the same, diameter of eye five 

 times in the length of the head ; two rows of large scales on the 

 operculum, the first of six or seven, the second four or five scales. 

 Operculum striated ; the two first dorsal spines ending in long 

 filaments ; caudal fin truncate ; pectorals large, rounded, of four- 

 teen rays ; ventrals united at the base, smaller than the pectorals, 

 with one long slender spine and four rays. Colour (in spirits) 

 reddish pink, becoming light brown on the back, with faint 

 traces of three or four irregular transverse brown bands, which 

 are interrupted a little under the lateral line, and reappear as 

 blotches on the belly. The head is brown above and pink below 

 and on the sides ; a narrow well defined blue stripe, bordered 

 with black, extends from the eye to the scaly part of the operculum ; 

 a second runs below the eye from the front of the mouth ; a third 

 extends from the angle of the mouth to the serrated part of the 

 pra3operculum. The spines of the dorsal fin are white, but the 

 membranes and filaments black ; the rest of the fin is yellow, with 

 a broad dark blue stripe nearer the margin than the base ; the 

 anal and ventral fins similar ; the caudal and pectorals are of a 

 fine yellow.
