The genus Seriphus, sufficiently characterized in the foregoing 

 key, contains but i species. This is 5. politus, the queenfish or white 

 croaker, which occurs on the Pacific coast from Point Conception to 

 Cerros Island. It is common on sandy shores, especially about San 

 Diego. It reaches a foot in length and is an excellent pan-fish.

 conic, rather pointed ; mouth very large, terminal, not very oblique, 

 the lower jaw projecting; maxillary very broad; teeth sharp, not close- 

 set, in rather narrow bands; tip of lower jaw without canines; upper 

 jaw with 2 long canines, one of these sometimes obsolete; canines 

 tapering from base to tip; lateral teeth of lower jaw larger than anterior; 

 preopercle with its membranous edge serrulate, its bony edge entire; 

 lower pharyngeals separate, their teeth all pointed; gill-rakers strong,

An important genus of large fishes, chiefly American, closely re- 

 lated to the Old-World genus Otolithus. All rank high as food-fishes, 

 the flesh being rich, but in some species tender and easily torn, hence 

 the popular name weakfishes. 



a. Scales not very small, the lateral line with 55 to 75 pores, the num- 

 ber of scales 55 to 85.
