Eye 3 in the snout, 4.6 in the head and 1.5 in the narrow inter- 

 orbital. Three indistinct spots along the back, at the base of 

 the dorsal spine and first dorsal rays and base of the last dorsal 

 rays and at the base of the adipose spine. Spots often con- 

 fluent; many small scattered chromatophores over the head and 

 sides. Dorsal with three or four cross-bars. D. I, 8; A. I, 6;

gg. Sides variously striped or spotted; most species with a series or a few 



scattered spots below the lateral line. Dorsal always and anal 



usually marked. Usually some grouping of the chromatophores on 



the face. 



/. A large intense black spot at the base of the dorsal spine, or on the first 



few dorsal rays, or on both. 



m. Dark spot at the base of the dorsal spine, sides of the body with 



numerous small black dots. 



n. Anal plain; a black spot at the tip of each dorsal ray. The 



small dark dots on the sides lacking along the lateral line; 



Face with blue reflections. Form stout, profile steep in 



front. Head 3 in the length; 1.4 in the depth; eye 3 in 



the head, 1.6 in the interorbital. Dorsal spine long, 



reaching the adipose when depressed. Four flat azygous

 mm. Dark spot in the anterior part of the dorsal fin. Sides with 

 several longitudinal rows of small spots. 

 o. An indefinite light stripe along the lateral line, anal with dark 

 spots or small dark dots. 

 p. A series of small spots in the light stripe along the 

 lateral line, upper parts of the head, upper two- 

 thirds of the body, caudal, dorsal, adipose, and anal 

 with gray (iridescent in life) point-like dots, snout 

 short; fontanel short; eye very small, 4 in the head. 

 Interorbital equal to the snout, 2 in the head.
