 caudal lobes scaled for about half their length. 



Dorsal spines subequal from the fourth or fifth, the last equal to half the length 

 of the head; dorsal and anal filaments frequently extending beyond the caudal, 

 the ventral filaments sometimes beyond the base of the anal; caudal truncate or 

 very feebly lunate; pectorals a little shorter than the head. 



Five obscure cross-shades in the young; two dark, parallel streaks from the eye 

 to the upper lip; a small, round, black spot at the base of the upper caudal ray; 

 sides of head with blue spots, which increase in size with age; scales of the sides 

 of the young with a bright blue dot, becoming diffuse with age; soft dorsal, caudal, 

 and latter part of anal with hyaline spots; dorsal sometimes with a black
