SPAROID FISHES OF AMERICA AND EUROPE. 481 
ANALYSIS OF SPECIES OF ANISOTREMUS., 
a. Scales above lateral line in series parallel with the lateral line. 
b. Dorsal spines rather low, the longest not more than half length of head; second 
t anal spine about half head. 
¢e. Pectorals much shorter than head, not reaching tips of ventrals; dorsal rays 
x1, 13, the spines comparatively slender, the longest half head; 
eye more than twice as wide as the narrow preorbital. Body com- 
pressed, considerably elevated, the greatest height below the fifth 
dorsal spine; profile rounded from base of first dorsal spine to the 
nape, concave over the eyes, descending abruptly down the snout; 
interorbital area twice orbit; snout thick and obtuse; teeth vil- 
liform in both jaws, with an outer series of conical teeth; pre- 
opercle serrate, strongly on angle; a posterior notch in opercle 
between two obtuse and feeble points; soft dorsal about as high as 
spinous; second anal spine long and strong; caudal emarginate. 
Color dusky-grayish, with four irregular crossbands, which grow 
faint with age; scales silvery with purple reflections; membrane . 
- between the scales brown; fins blackish. Head, 3!; depth, 22 to 
23; D. x1, 138; A. 1, 10. Scales, 7-47-13; second anal spine, 2 in 
head; fifth dorsal spine, 2; pectoral, 44.............Pacrrict, 51. 
cc. Pectorals a little longer than head, about reaching anal fin; dorsal rays xu, 
16, the spines short and stout, the longest 24 in head; eye 34, 
about one-fourth wider than the broad preorbital. Body ovate, 
compressed, the back rather strongly arched; anterior profile, 
rather steep and straightish, slightly depressed above eyes and at 
the nape; snout very short, blunt and thick; mouth very small, 
the maxillary not quite reaching to front of eye; lower jaw in- 
cluded; teeth cardiform, in broad bands, the outer series enlarged, 
but smaller than in A. pacifici ; preopercle rather weakly serrate; 
gill-rakers short and weak, about 10 below angle; dorsal fin low, 
rather deeply emarginate, the soft rays more than two-thirds 
height of longest spines; anal rather low, its margin perfectly 
straight; second anal spine very robust; caudal moderately forked. 
Color grayish silvery; a faint dark bar from front of dorsal to level 
of base of pectorals; lower parts of sides with indistinct darker 
streaks; vertical fins and pectorals dusky yellowish; distal half 
of ventrals and base of anal blackish. Head, 3}; depth, 24; D. x11, 
16; A. 11, 9; scales, 6-52-13; eye, 34; snout, 3; preorbital, 23; 
maxillary, 3}; second anal spine, 2; fourth dorsal spine, 24; pec-

bb. Dorsal spines very high, the longest 12 in head; second anal spine very long, 
about 13 in head; pectorals much shorter than head; interorbital 
area much less than width of orbit; snout obtuse, not much longer 
than eye; cleft of mouth small, the maxillary extending to front 
of eye; dorsal and anal spines exceedingly strong, the third dorsal 
spine the longest; snout naked, the remainder of the head being 
scaly ; each ray of the soft fins accompanied by a series of minute 
scales, covering the caudal; caudal fin slightly emarginate. Color 
gtayish-silvery, with five jet-black crossbands in the adult; fins 
blackish. Head, 3; depth, 2; D. x11, 16; A.111, 9; scales, 8-48-15; 
second anal spine, 1; third dorsal spine, 12 ........--. Dovu, 53. 
aa, Scales above lateral line arranged in oblique series which are not parallel with 
the lateral line,
