very variable iii its development, but usually consisting of few rather 

 large teeth, increasing in size forwards, the anterior tootli 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 villiforra 

 teeth on the base of the tongue, marked ofl' by a constriction from the 

 terminal patch. 



Gill-rakers 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 occujiied by the suboperculum. 



Pectoral of fourteen rays, the third or fourth longest, narrow, the 

 rays bifurcate. Tips of the pectorals distant from the ventrals more 

 tban the length of the ventrals. 



Ventrals not greatly shorter than the pectorals ; the rays bifurcate, 

 their tii)S not reaching to the anus; insertion of ventrals about one 

 scale in advance of that of dorsal. 



Dorsal of one spine and ten bifurcate rays, highest in fmnt, 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— i%, 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 scales upon the fins. 



Adipose fin falcate, rather large. 



Color of the fresh Jish. — 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. A very 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. Operculum 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.
