greater than the height and about two thirds of the length. The

 space. The maxilla extends to the vertical from the posterior 

 margin of the eye. The length of the pectoral is greater than the 

 length of the head ; the length of the caudal is contained four 

 times and one third in the total length of the body. The third 

 dorsal spine is produced into a short filament rather higher than the

 and a half times the length of the head ; the width of the head ia 

 rather greater than the height, and two thirds of the length. The 

 height of the body is less than one fifth of the length. Scales on 

 the nape, shoulder, and belly cycloid, rest ctenoid ; those on the 

 side rather larger than those on the tail, and much larger than those 

 on the anterior parts. The diameter of the eye is a quarter or one 

 fifth of the length of the head, and about half the interorbital 

 space. The maxilla extends to the vertical from the middle of the 

 eye. The length of the pectoral is greater than that of the head ; 

 the length of the caudal is about one fifth of the total length of the 

 body. The third dorsal spine is rather higher than the body. 

 Colour, body blackish-violet, becoming lighter below ; caudal yellow, 

 with a broad violet band round the margin ; the other fins brownish- 

 violet.
