Genus I—SERIPHUS. 
Seriphus Ayres, Proc. Cal. Acad. Nat. Sci., ii, 80, 1861 (politus). 
TYPE: Seriphus politus Ayres. 
This genus consists of a single species, abundant on the California 
coast. 
It is one of the most aberrant genera in the family—as compared with 
the typical scizenoid forms, standing at the farthest possible extreme 
from Hques, Pogonias, and Menticirrhus. 
ANALYSIS OF SPECIES OF SERIPHUS. 
a. Body moderately elongate, compressed ; profile slightly depressed over the eyes; 
* eyeslarge, 44in head; snout projecting, 34in head; mouth large and narrow, the lower 
jaw more or less projecting in the adult; premaxillary anteriorly about on the level 
of the lower margin of the pupil; maxillary 2 in head, reaching to below posterior 
margin of eye; lower jaw with a knob at its symphysis which fits in a notch in the 
upper jaw ; teeth allsmall, subequal; those of the lower jaw ina single series, except 
at the symphysis, where there are two or three series ; those of the upper jaw in two 
series, the inner ones much recurved ; gill-rakers long and slender, } length of eye, 
7-++-16; lower pharyngeals narrow, linear, fragile; scales moderate, weakly ctenoid, 
those about the head cycloid; lateral line straight ; dorsal spines weak, the highest 3 
in head ; soft dorsal faleate, the anterior rays much the longer ; anal similar, its base
