upper profile of head rounded. Diameter of eye 4^ in the length 

 of the head and as long as the snout. Interorbital region flat, 

 its width 74 in the head; supraciliar^'- ridges rather feeble. Max- 

 illary extending to the vertical from the middle of the eye, its 

 length from the tip of the snout ^ of the head, its width at the 

 distal extremity |- of the diameter of the eye. Anterior canines 

 strong and hooked, those of the upper jaw the longest; lower jaw 

 with a pair on each side; vomerine teeth in an obtusangular 

 band, the outer slightly enlarged; pectoral band biserial. Pre- 

 opercle finely and evenly serrated on its vertical limb, the lower 

 with two or three strong antrorse spines; middle opercular spine 

 the strongest, nearer to the lower than to the upper; lower spine 

 not further back than the upper; subopercle with three or four 

 small denticulations inferiorly. Gill-rakers 6 -f 7, those on the 

 upper branch rudimentary; the longest ^ of the diameter of the 

 eye. Dorsal fin originating above the outer border of the opercle 

 and terminating well behind the anal; spines moderate, the tenth 

 as long as the third, the fifth the lonijest, 24 in the head and 4 

 of the longest soft I'aj'^s : second anal spine stronger and longer 

 than the longest dorsal spine, 2| in the head and | of the second 

 and longest soft ray : ventral spine strong and curved, not quite 

 so long as the second anal, its length | of the outer ray, which is 

 1§ of the head and nearly reaches to the vent: pectoral with 15 

 rays, 14 in the head : caudal emarginate, the outer rays ^, the 

 middle ^ of the total length; caudal peduncle deeper than long, 

 its least depth 2f in the depth of the body. Scales of opercle 

 nearly as large as those of the body; on the rest of the head much 

 smaller. Lateral line well marked, the anterior tubes bifurcate, 

 the posterior simple and straight Dark reddish-brown, the sides
