The height of the body is two-sevenths of the total length ; snout obtuse, much 

 shorter than the diameter of the orbit, the width of which is more than that of the in- 

 terorbital space. There are only six small incisors anteriorly in the upper jaw, and 

 eight in the lower, the lateral teeth being very small. Prseorbital very narrow and not 

 serrated ; operculum with two spines. The scales on the upper side of the head do not 

 advance to the front margin of the orbit. Of the dorsal spines, the fourth, fifth, and 

 sixth are the longest, the posterior ones being a little shorter ; the soft portion of the 

 anal and the caudal lobes are produced into points. 



Colour pale bluish above, white below, the scales being marked with darker-blue 

 elongated spots arranged so as to form longitudinal lines. A deep-black spot supe- 

 riorly at the axil of the pectoral. 



Length 2 to 4 inches.
