premaxillaries, 4.5 to 4.9 in head; eye small, somewhat oblong, its 

 longest diameter oblique to axis of body, extending downward and 

 backward, longitudinal diameter 4.8 to 5.4; interorbital 3.2 to 4.0; 

 mouth moderately oblique, terminal, the gape anteriorly on or a 

 little above level of lower margin of eye; maxillary extending nearly 

 or quite under posterior margin of pupil, 2.2 to 2.5 in head; teeth 

 in each jaw in a band, the outer series in upper jaw enlarged; preopercle 

 with about 6 or 7 rather strong spines, all directed more or less 

 backward; gill rakers at angle nearly as long as eye, 20 or 21 (rarely 

 19 or 22) on lower and 11 or 12 (rarely 10) on upper limb of first arch, 

 total number 30 to 34; lateral line rather strongly arched, becoming

caudal and anal rather densely, the rows above lateral line more or 

 less parallel with it, 4 or 5 rows between it and first dorsal spine; 

 dorsal fins somewhat connected, the second spine much stronger, 

 though shorter than the immediately succeeding ones, the third one 

 usually longest, 1.6 to 2.0 in head; second dorsal scarcely higher 

 anteriorly than posteriorly, the longest rays about equal in length 

 to second spine of first dorsal; caudal somewhat pointed, especially 

 in young; second anal spine rather strong, about as long as adjacent 

 soft ray, 1.5 to 1.9 in head; ventral inserted under base of pectoral, 

 1.2 to 1.6 in head; pectoral reaching little beyond tip of ventral, 

 scarcely shorter than head, 3.6 to 3.9 in head. 



Color grayish brown above, with bluish reflections; this color 

 shading into the pale silvery of the lower parts; a small elongate dark 

 area above free margin of opercle; fins more or less olivaceous, all with 

 dusky points, largest on anal, ventral, and pectoral, these fins quite
