D. vi.-vii., 10-11; A. iii., 10-11; P. 14; \'. i.-5 ; C. 17; 

 sc. hit. J5-26; sc. tr. 3 + 7. Depth nearly ji, head 3J in the 

 length to the h}pural. Eye 2^-3, orbit 2^ in the head, and 

 twice as long as the snout. Interorbita! width i^ in the orbit. 

 Caudal peduncle 2 in the head. 



Body rather deep, compressed. L'pper anterior profile 

 interrupted over the eye, the back between the nape and the 

 dorsal more or less keeled. Supraorbital ridge smooth 

 anteriorly, armed with three to five spines on its posterior 

 portion which is bent downwards. Antero-inferior orbital 

 ring crenulate or spinulate. Preorbital strongly denticulate. 

 Lower limbs of preoperculum denticulated, all the other bones 

 smooth. Maxillary reaching to below the anterior margin of 

 the eye. Two rows of scales on the cheeks, one behind the 

 •eye ; operculum with large irregular scales, a single row on 

 the interoperculum. Minute teeth on the jaws, vomer, 

 palatines and tongue, (iill-rakers flattened, spinulate on their 

 inner edges, the longest about half as long as the eye. 



Scales of the body extending forwards to abo\e the middle 

 of the eye and onto the bases of the dorsal, anal and caudal 

 hns. Lateral line interrupted below the spine of the second 

 dorsal or farther forward, each scale with its free margin 

 notched. There are ten to thirteen scales on the first portion 

 which is arched, and twelve to fourteen on the straight 

 portion. 



Origin of the first dorsal a little nearer the end of the 

 second than the tip of the snout. The first spine short, the 

 second strong and subequal to the third and ij to i^ in the 

 head ; the last is joined to the second dorsal by membrane. 

 Spine of the second dorsal two-thirds as long as those of the 

 first, shorter than the anterior rays. Anal commencing and 

 terminating behind the second dorsal, its base either slightly 

 longer or shorter than that fin ; the first spine short, the second 

 and third long and stout, the last as long as the rays but 

 •shorter than the second dorsal spines. Pectorals almost 

 reaching the vertical of the first anal spines. \'entrals reach- 

 ing to or slightly beyond the vent which is placed well in 

 .advance of the anal fin. Caudal deeply forked.
