The height of the body is from three and a-fifth to three and 

 a-third times in the total length, the length of the head about 

 four and a-half times. The diameter of the eye is two and three 

 quarters in the length of the head, longer than the snout, and 

 equal to the distance between the eyes. Praeorbital half as wide 

 as the orbit, with a very long and strong spine and some 

 denticulations beneath — the second of these terminating posteriorly 

 in a small point, above the tip of the large spine. Prseoperculum 

 with strong short spinous teeth, each with a small hook at the 

 base ; the angle projecting backwards, strongly armed. The 

 spines of the fins moderate, the second anal stronger but not 

 longer than the third. The upper lobe of the tail longest. 

 Greenish-olive, each scale with a pearl-coloured base. The 

 marginal half of the dorsal fin violet.

 The height of the body is about the length of the head and 

 one-fourth of the total length. The diameter of the eye is rather 

 shorter than the snout, and is three and three-fourths in the head. 

 The prseorbital is three-quarters as wide as the eye, with a small 

 spine and some denticulations beneath ; preeoperculum with the 

 posterior limb very finely serrated, and the angle rounded. Spines 

 of fins moderate, the second anal shorter than the third. Caudal
