 short, snout short and blunt, equal to eye in length; lower jaw slightly 

 included; maxillary short, nearly straight, little expanded at tip, scarcely 

 reaching vertical at posterior edge of orbit; eye large, equal to length of 

 snout; teeth on jaws and niaxillaries in a single row, those on vomer and 

 tongue in adouble row and well developed; gillrakers 3 + 9 or 4 + 8,

 its least depth which is 2.3 in head. 



Fins all rather small; pectoral short and rounded, its length 1.5 in head; 

 origin of dorsal midway between tip of snout and base of caudal tin, base 

 of fin equal to length of longest ray which is 2 in head, distal edge nearly 

 straight; base of anal shorter than longest rays, which are a trifle shorter 

 than longest dorsal rays; caudal forked, the lobes bluntly pointed, their 

 length 1.4 in head; ventrals short, not reaching vent, 1.8 in head. 



Scales very small, reduced in size and much crowded anteriorly; lateral 

 line well developed ; small scales on base of caudal fin. 



Color in life (from field notes furnished by Mr. Nelson), back and top 

 of head olive, shading down into silvery on the opercle and on side below 

 lateral line; ventral surface dull white; throat white; back and upper 

 part of side with small black spot- and showing a slight golden bronze 

 luster strongest along lateral line and fading below into silvery; a rather 

 indistinct light reddish purple band across opercle and alongside to cau- 

 dal fin, this appearing to overlie the ground-color; dorsal and caudal fins 

 grayish olive, with black spots ; adipose fin olive, spotted with black ; pec- 

 toral fins plain, dingy grayish ; ventral fins dull olive with a terminal band 

 of white at tip; anal fin olive, mottled indistinctly with blackish and 

 edged on tips of anterior rays with an oblique band of white; eyes dull 

 olive-brown, with golden luster. ( Some small examples had the pectoral and 

 ventral tins distinctly yellowish). 



Color inspirits, caudal peduncle and entire side above lateral line closely 

 covered with small stellate or irregular black spots; top of head somewhat 

 less thickly covered with roundish black spots and a few similar spots on 

 upper part of opercle; body below lateral line with smaller, less distinct 

 spots; about 11 oblong vertical parr-marks on side (most distinct in 

 smaller examples) ; dorsal fins with about 5 rows of rather larger black 

 spots, a subterminal black area on anterior rays which are tipped with 

 light orange; caudal sjjotted with black, the spots smaller than those on
