very variable in its development, but usually consisting of few rather 
large teeth, increasing in size forwards, the anterior tooth sometimes 
quite a large canine. Teeth in front part of tongue in a single series 
on each side, with a single terminal tooth; all the teeth large and curved, 
the terminal tooth largest. <A large patch of several rows of villiform 
teeth on the base of the tongue, marked off by a constriction from the 
terminal patch. 
GilLrakers long and slender, those of first pair of branchial arches 
half as long as the eye, the others diminishing gradually. Branchios- 
tegals seven. 
Angle of preoperculum a little more than a right angle, both the pos- 
terior and the inferior margins nearly straight. Posterior margin of 
gill-cover forming a bold and almost regular curve, its most posteriorly 
produced portion occupied by the suboperculum. 
Pectoral of fourteen rays, the third or fourth longest, narrow, the 
rays bifureate. Tips of the pectorals distant from the ventrals more 
than the length of the ventrais. 
Ventrals not greatly shorter than the pectorals; the rays bifurcate, 
their tips not reaching to the anus; insertion of ventrals about one 
scale in.advance of that of dorsal. 
Dorsal of one spine and ten bifureate rays, highest in front, the height 
about twice the length of the base; the second ray slightly longer than 
the first, the last longer than the spine. Anal commencing at about 
the posterior third of the total length, and consisting of seventeen 
branched rays, the first very short, the second nearly equal to the third 
and longest, the fourth nearly equal to the third, thence descending 
gradually. 
Caudal deeply emarginate, almost forked; rays 11-10-9—5,, principal 
rays several lines branched. 
Lateral line not very distinct, running along the center of the silvery 
band of each side. Scales rather large, their exposed portion forming 
a diamond-shaped pattern, each diamond about twice as deep as long. 
Head scaleless. 
No seales upon the fins. 
Adipose fin faleate, rather large. 
Color of the fresh fish—Light greenish gray on the back, the pattern 
of the scales marked by a series of black dots around the edge of each ; 
these die out upon the silvery lateral line. Avery bright silvery line 
along the side, reaching one scale above lateral line; the upper boundary 
of this band distinct, the lower fading into the silvery-white of the 
belly. Opereulum and suboperculum bright like the lateral band, ex- 
cept above, where they become greenish gray like the back; snout and 
cheeks darker greenish gray than the back. Lower jaw with black 
points below and on the sides, closer together toward the tip. Fins 
spotted with dark points. Forehead between eyes almost black; eyes 
silvery ; pupil black. 
Locality, San Francisco.
