Habitat.—Coast of Southern California, north to San Francisco. 
This little fish is generally common along the coast of Southern Cali- 
fornia, where it is a food-fish of some importance and is usually known 
as the “Little Roncador.” 
Genus XIX.—MICROPOGON. 
Micropogon Cuvier & Valenciennes, Hist. Nat. Poiss., v, 213, 1830 (lineatus= 
Surnieri.) . 
TyPeE: Micropogon lineatus Cuv. & Val.= Umbrina furnieri Desmarest. 
The species of this well-marked genus are very closely related and 
are all American. 
ANALYSIS OF SPECIES OF MICROPOGON. 
a. Dorsal rays X-I, 28 to 3 
b. Scales comparatively wre about 9 in a vertical series between faith of dorsal 
and lateral line, 12 in an oblique series ; outer teeth of upper jaw evidently 
enlarged ; dark spots on scales above lateral line not forming continuous 
stripes; 16 scales in an oblique series from vent upward and forward to lateral 
line. Body rather robust, the back elevated; profile regularly rounded, 
scarcely depressed above eyes; snout 3 in head; eye 5in head; preorbital 
broader than eye; preopercle strongly serrate along its whole posterior mar- 
sgin; maxillary reaching front of pupil, 3 in head; gill-rakers slender, very 
short, numerous, about 7 + 16; third dorsal spine 2 in head; pectoral 12 in
