464 Storer on the 
covers silvery ; the division between the opercle and 
preopercle, scarcely distinguishable at first sight ; the 
posterior angle of the operculum obtuse. Body grad- 
ually arched to the origin of the first dorsal. 
The first Dorsal fin arises opposite the middle of 
the pectorals, is one third longer than high, and of 
the same color as the back. 
The second Dorsal fin is one third longer than 
the first; it arises back of the first, at a distance 
equal to less than one third the length of the first 
dorsal. The distance between the second and third 
dorsals, is to the distance between the first and sec- 
ond, as 3 to 1; height of the third dorsal to its 
length, less than 1 to 3. 
The Pectorals arise on a line with the posterior 
angle of the operculum, some distance beneath it; 
their length to their height, as 2 to 12; the color, of 
the dorsal fins. 
The Ventrals are very small, in front of the pec- 
torals; the second and third rays longest; fins 
white. 
The Anal fin at its base, the color of the abdomen ; 
above, bluish ; arises upon the same plane, and ter- 
minates with the second dorsal. The second anal 
about half the height of the first anal; a narrow 
white margin at its base, and, like the first, whitish at 
the tip. 
The Caudal fin large, strong, forked; length of 
the outer rays equal to the distance between the ex- 
tremities of the fin when expanded. 
In smaller specimens, the color above is deeper ; 
the abdomen, reddish.
