front of the dorsal fin, each terminating in a small hook, directed 

 forwards. The fii'st interhnsmal is very strong, with two divergent 

 anterior lidges, leaving a deep groove between them ; it is attached 

 to the eleventh vertebra, and its length equals that of the first seven 

 vertebrae.

■ The height of the body is nearly equal to the length of the head, 

 and somewhat less than one-fomth of the total. The snout is of 

 moderate extent, longer than the diameter of the eye, which is one- 

 foiu'th of the length of the head. The upper jaw is rather longer 

 than the lower ; the maxillary extends nearly to the vertical from 

 the anterior margin of the orbit. The posterior limb of the prae- 

 operculum very slightly emarginate, serrated ; the angle not promi- 

 nent, rounded, and with rather stronger denticulations. The dorsal 

 fin deeply notched ; the spines slender, but scarcely fiexible ; the 

 fifth dorsal spine longest, one-half the length of the head. Caudalia 

 emarginate ; the second anal spine not strong, and shorter than the 

 thii'd. On each side two to six brownish-black longitudinal bands ; 

 if two, one from the eye to the root of the caudal, the other above 

 the lateral line.
