Scales only moderately adherent, often lost in preserved specimens; apparently 

 not different from those of P. aestivalis-^ 14 longitudinal rows between base of pelvic 

 and base of dorsal. Ventral scutes strong, 18—21 in advance of pelvics, 12 — 16 

 behind them. 



Head less than depth, often fully by diameter of eye, 2.8-4.2. Snout 4.1-6.0. 

 Eye large, longer than snout at all ages, 2.5—4.0. Interorbital 4.0—7.3. Mouth 

 oblique, as in P. aestivalis; margin of lower jaw within mouth with a somewhat 

 broader angle (Fig. 760); other characters about the mouth, including Teeth, as in 



Figure 82. Pomolobus pseudoharengus, 300 mm TL, from a market in Washington, D. C, USNM 25197. 



P. aestivalis. Maxillary 1.8—2.8 in head. Gill rakers at angle of first arch about 0.66 

 of diameter of eye, increasing in number with age; 25—33 on lower limb in examples 

 30-49 mm SL, 32-36 in specimens 50—69 mm, 30—39 in specimens 70— 89 mm, 35—38 

 in specimens 90— 109 mm, 36—40 in specimens 1 10—129 mm, 36—40 in specimens 

 130—149 mm, and 38—44 in examples 210— 270 mm (adults). 



Dorsal fin with a straight to slightly concave margin, its origin definitely less than 

 an eye's diameter in advance of pelvic fin and usually nearer to margin of upper jaw 

 than to vertical from last ray of anal. Caudal deeply forked, the lower lobe a little longer 

 than upper lobe, often exceeding head length by nearly the diameter of eye. Anal low, 

 with an almost straight margin, its origin about equidistant between base of pelvic 

 and base of caudal. Pelvic fin inserted near ventral edge and usually equidistant be- 

 tween base of pectoral and origin of anal, 1.75—2.5 in head. Pectoral fin somewhat 

 higher on side, reaching about 0.66 of the distance to pelvic in adults and nearly to 

 pelvic in some small examples, 1. 1—2.0 in head. 



Color. Fresh specimens, grayish green above. Sides silvery. Rows of scales on 

 upper part of side sometimes with more or less definite dusky lines in adults. A small
