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

 forwards. The fiist interhaemal is very strong, with two divergent 

 anterior ridges, 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-fourth of the total. The snout is of 

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

 fourth 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 flexible ; the 

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

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

 third. 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.
