 2J in head ; color bluish above, silvery below ; a dusky blotch on center 

 of opercle ; back and sides with distinct streaks of deep olive following 

 the centers of the rows of scales, these lines regular and not interrupted; 

 they run obliquely upward and backward below as well as above the 

 lateral line, those below being more nearly horizontal ; fins chiefly bright

e. Second anal spine large, 2 in head ; profile straight, moderately steep ; 

 . snout rather acute ; eye 4£ in head ; mouth small, inferior, the maxillary 

 nearly reaching middle of orbit, its length 2£ in head ; teeth subequal; 

 gill-rakers scarcely developed, 4 + 9 ; third dorsal spine highest, If in 

 head ; anterior dorsal rays much longer than posterior ones ; anal fin 

 pointed, the second soft ray longest, the second spine very strong, 2 in 

 head ; ventrals slightly longer than pectorals, 1£ in head ; lateral line 

 moderately arched anteriorly ; color bluish, silvery below ; conspicuous 

 dark lines following the rows of scales, those below lateral line oblique 

 as well as those above ; spinous dorsal dusky. Head 3?- in length ; depth 

 3£. D. X-I, 26; A. II, 6; scales5-48-8 Xanti, 91. 



ee. Second anal spine short and thickish, 3 in head. Back elevated, the an- 

 terior profile steep and rather convex; snout blunt, much protruding; 

 mouth small, horizontal ; the maxillary reaching just past pupil, 3 in head ; 

 eye 5 in head ; preopercle finely and sharply serrate ; gill-rakers very 

 small ; pectoral short, 1^ in head ; longest dorsal spine 2 ; caudal fin 

 slightly lunate, the upper lobe the longer ; scales above lateral line iu 

 very oblique series, in oblique series below lateral line anteriorly ; color, 

 grayish, yellow below ; faint dark lines along the scales on the upper 

 half of the body, golden lines on scales below ; dorsals finely punctu- 

 late; fins pale ; gill cavity pale within. Head 3f to 3f; depth 3i to 3£.
