Body oblong, pointed, the back little elevated; head moderately long and pointed; snout Ion®, 
conic, the jaws subequal; maxillary broad, triangular, its greatest width 2 in its length; supplemental 
maxillary long and narrow, slipping under the thin preorbital; teeth in broad villiform patches on 
jaws, vomer, and palatines, tongue naked; eye small, somewhat anterior; interorbital space broad, con¬ 
vex; preopercloand operele ent ire; gillrakers about all below the angle, cephalic ones gradually shorter, 
longest about 1.5 in eye; fins moderate; origin of spinous dorsal over tips of pectorals, the rays weak 
and short, folded somewhat in a groove, the longest 2 in snout, the fin not connected to soft dorsal; 
soft dorsal long and low, anterior rays elevated, longest 2.9 in head, last ray equal to eye; last ray of 
dorsal finlet produced, its length 3.6 in head; distance between dorsal finlet and base of last dorsal 
ray I in eye; distance from last ray of dorsal finlet to base of caudal lobe 3.6 in head; origin of anal

dirty white; fins dusky, yellowish, or olivaceous. In life 2 conspicuous blue bands on side of body, 
the upper beginning at orbit and passing to dorsal margin of caudal peduncle, its width about equal to 
that of eye, the other beginning at snout and passing along the lower margin of orbit across operele 
and above pectoral fin to the caudal; caudal yellowish with a darker margin; centrals and pectoral
