Habitat.—Coast of Southern California, north to Santa Barbara. 
This species is rather common on the coast of Southern California, 
where it is a food-fish of some importance. It reaches a weight of 5 or 
6 pounds, . 
The black ocellus on the base of the pectoral fin in this species is as 
characteristic as that at the base of the caudal in Sciena ocellata. 
Genus XIV.—LEIOSTOMUS.

“TypE: Leiostomus xanthurus Lacépede. 
This genus, as now understood, contains but a single species. It is 
distinguished from Scicena chiefly by the obsolescence of the teeth in 
the lower jaw, aud by the more paved teeth of the pharyngeals. The 
soft rays of the dorsal fin and especially of the anal are more numerous 
than in related groups.
