 about 95 in a longitudinal series; eye 6 in head; highest dorsal spine 2J; 

 pectoral 2^; ventrals 2. Body elongate, shaped much as in the weakfish; 

 maxillary extending lieyond pupil, 2i in head; canine large, usually but 

 a single one present; snout rather sharp, 4 in head; gill rakers shortish, 

 4 + 7; pharyngeals narrow, their teeth small, cardiform, the inner ones 

 somewhat enlarged; soft rays of dorsal and anal scaleless; caudal fin 

 somewhat lunate in the adult, the middle rays shortest, although more 

 or less produced in the young; pectoral fin short, not reaching tips of 

 ventrals. Color clear steel blue above, without stripes or spots; silvery

 California as far north as San Pedro. It is an excellent food-fish, not infe- 

 rior to its relative, the weakfish of tie Atlantic coast. As in the case of 

 the latter species, the rtesh of Cynoscion liarviplnnis is soft, and the fish 

 does not bear transportation well, {parvus, small; pinna, fin.)
