rounded, those behind have rounded crowns. Fins dorsal spines 

 increasing in length to the third, which is scarcely so long as the 

 longest ray; second anal spine not so long as third, which equals 

 length of second dorsal, and is nearly as high as the rays ; caudal 

 emarginate. Colour olivaceous brown, becoming lighter on abdo- 

 men ; the centre of each scale with a cobalt-blue spot, so as to form 

 longitudinal lines, in some specimens there are intermediate yellow- 

 bands ; inside of mouth orange ; pectoral flesh-coloured, base of its 

 second ray bright blue ; dorsal, caudal, and anal slate-coloured, 

 margined with orange, and having a line of spots along the centre 

 of the rays; ventral externally slate-coloured. In most adult 

 specimens there is a faint quadrangular spot between lateral line 

 and pectoral and also indistinct vertical bauds. In some the edges 

 of the opercle, subopercle, and branchiostegal rays are blood-red.
