eye, second and third increasing in height, as usual; soft portion little 

 higher than that of dorsal. Veutrals short, 2| in head ; pectorals fan- 

 shaped, 2| in head. 



Most of the tubes of lateral line simi^le. 



Color in spirits, chocolate above, lighter below ; a narrow light band 

 crosses the back immediately behind soft-dorsal fin, fading out just before 

 it reaches the space close behind anal, thus outlining the base of caudal 

 peduncle; this light mark extending up on the dorsal fiu, almost meeting 

 the central light line of the dorsal, the pedunculate baud seeming to 

 be a contiuuation of the middle dorsal line. A light streak outlines the 

 cheek superiorly, becoming fainter where it extends across opercles to 

 the upper base of pectoral. A series of similar light lines extends ob- 

 liqueiy downward from eye across cheeks and opercles; these lines 

 somewhat waving, and coalescing more or less; two or three light 

 streaks on preorbital, running from eye toward snout; nasal region ver- 

 miculate, with similar light markings. Dorsal fin chocolate, with two 

 light lines running lengthwise of the fiu; soft part brownish only at 

 base, transparent superiorly, yet somewhat dusky. Caudal copper- 

 green, its outer rays of a brown, like the back ; anal light, tinged with 

 green; a very dark brown spot on base of veutrals, covering half the 

 fin ; pectorals transparent, uniform yellowish ; teeth greenish.
