 barred. Mouth very small, maxillary reaching slightly beyond vertical

Silvery, brownish above, centre of scales with a darker spot; a black 

 spot on spinous dorsal ; young with transverse dark bars. Body oblong, 

 compressed, highest at front of spinous dorsal ; profile steep, not arched ; 

 mouth horizontal, maxillary reaching to below eye ; eye large. Head 3f 

 in length ; depth 2.\ ; eye 3 in head. D. IX, 10 ; A. Ill, 8. L. lat. about

"The height of the body is contained 3 to 3^ times in the total length 

 without caudal, the length of the head 3 to 3 times; the diameter of 

 the eye excels the length of the snout and is contained 3 times in the 

 length of the head and equals the width of the interorbital space ; the 

 groove for the processes of the interinaxillaries is naked and extends to 

 the vertical through the anterior third of the eye; the free portion of 

 the tail is longer than high ; the least height of tail equals the length of 

 the <;th dorsal spine ; the 3rd dorsal spine is the longest, its length being 

 contained twice in the height of the body and equals the length of the 

 head without the postorbital portion; the last dorsal spine equals in 

 length the I'd anal, and about equals the length of the snout, and is about 

 ;-; as long as the :>d ; the first dorsal ray is fully 14 times as long as the 

 1st dorsal spine: the I'd anal spine is stronger and shorter than the 3rd, 

 its length being contained 3r in the length of the head; the 3d anal 

 spine is contained .'!.\ times in the length of the head; the caudal is 

 lurked, its length slightly less than the length of the head, and very 

 little greater than the length of the pectoral; the pectoral reaches to 

 the perpendicular through the origin of the soft dorsal. The ventral is 

 half as long as the head; the vent is under the I'd ray of the soft dor-
