of the third ray ou each side; rays usually only ouce bifurcate. Veii- 

 trals small ; their posterior axil about half the width of the pectoral base 

 iji advance of the anterior axil of that tin, their tips extending beyond 

 the anus ; four lower rays bifurcate. Pectoral of colored side lanceolate, 

 about half the length of the head ; third ray longest, second slightly 

 shorter ; all the rays but the three uppermost once bifurcate. Pectoral 

 of blind side shorter, the central rays longest 5 most of the rays once 

 bifurcate. Scales of body and cheeks ctenoid, the spines well developed, 

 those on the cheeks similar ; no stellate or rugose scales on any part. 

 Small ctenoid scales on interorbital area ; snout and lower jaw scaleless. 

 A row of ctenoid scales along each ray of dorsal and anal tins on the 

 colored side, except upon a few of the anterior rays and those posterior 

 ones which incline forwfirds. The scales extend to the tips of the rays. 

 Similar scales upon the colored side of the caudal for the greater portion 

 of the length, and some on the outside of the pectoral. Scales of blind 

 side smooth; preopercular bone scaleless; the other opercular bones 

 partially so. A row of smooth scales along the front edge of each ray 

 of the central portion of dorsal and anal on the blind side, not extead- 

 ing above ^ of the length. Lateral line with about 82-86 scales ; a more 

 or less conspicuous arch above the pectornl, in most cases rising about 

 two scales high. Accessory lateral line ending below the 23d-27th dor- 

 sal ray on the colored side, and below the 16th-24th ray on the blind 

 side. A branch from the main lateral line joins the accessory line a 

 little posterior to its origin, the accessory line forming an obtuse angle, 

 or sometimes branching, at the junction. Color nearly uniform grayish 

 brown on the colored side; blind side white. Each scale of colored side 

 mth a dark band behind the spines, then a light area. Fins on colored 

 side nearly the same color as the body.
